Release Notes

avajs/ava ### [`v3.15.0`](https://togithub.com/avajs/ava/releases/v3.15.0) [Compare Source](https://togithub.com/avajs/ava/compare/v3.14.0...v3.15.0) #### Automatic snapshot file removal When you stop using snapshots in a test file, the next time you run `ava --update-snapshots` we'll remove the left-over snapshot files. Thanks [@​ninevra](https://togithub.com/ninevra)! [`4f093ab`](https://togithub.com/avajs/ava/commit/4f093ab) #### TAP improvements [@​tymfear](https://togithub.com/tymfear) has been on a roll improving our TAP reporter. `t.log()` output is now compliant with the spec [`99ab93a`](https://togithub.com/avajs/ava/commit/99ab93a). Tests that did not run due to timeouts are now reported [`98595da`](https://togithub.com/avajs/ava/commit/98595dae58209a9062d0238c7a3dd7078a9962d1). #### Next-generation configuration AVA 4 will add full support for ESM configuration files as well as allowing you to have asynchronous factory functions [`a2f2614`](https://togithub.com/avajs/ava/commit/a2f2614cc1e34fb9a7aa204b37b3b25559f203d9). If you're using Node.js 12 or later you can opt-in to these features in AVA 3 by enabling the `nextGenConfig` experiment. Say in an `ava.config.mjs` file: ```js export default { nonSemVerExperiments: { nextGenConfig: true }, files: ['unit-tests/**/*] }; ``` This also allows you to pass an `.mjs` file using the `--config` argument. With this experiment enabled, AVA will no longer have special treatment for `ava.config.js` files. Instead AVA follows Node.js' behavior, so if you've set [`"type": "module"`](https://nodejs.org/docs/latest/api/packages.html#packages_type) you must use ESM, and otherwise you must use CommonJS. You mustn't have an `ava.config.mjs` file next to an `ava.config.js` or `ava.config.cjs` file. *** See https://github.com/avajs/ava/compare/v3.14.0...v3.15.0 for all changes. ### [`v3.14.0`](https://togithub.com/avajs/ava/releases/v3.14.0) [Compare Source](https://togithub.com/avajs/ava/compare/v3.13.0...v3.14.0) #### Snapshot ordering With this release, snapshot files are now ordered based on test declaration, not completion. This makes it easier to compare the human-readable reports to your test file, and also stops the `.snap` from changing when the reports themselves don't. You'll want to rebuild snapshots after upgrading to this release to isolate any changes. Thanks [@​ninevra](https://togithub.com/ninevra)! [`e66b54c`](https://togithub.com/avajs/ava/commit/e66b54ce61d8bb16bbcd15b7fb90893d02e5a65c) #### Shared workers We’ve been working on making AVA more extensible. One major step on this path is our new shared worker support: run code in the main process, communicate with test workers and influence execution. Find out more in our [shared workers recipe](https://togithub.com/avajs/ava/blob/master/docs/recipes/shared-workers.md). *** See https://github.com/avajs/ava/compare/v3.13.0...v3.14.0 for all changes. ### [`v3.13.0`](https://togithub.com/avajs/ava/releases/v3.13.0) [Compare Source](https://togithub.com/avajs/ava/compare/v3.12.1...v3.13.0) - `t.passed` can now be used in tests and teardown functions. Thanks [@​tymfear](https://togithub.com/tymfear)! [`900dc6d`](https://togithub.com/avajs/ava/commit/900dc6d46a1f8728dddfab1e42caef1fa8a51c85) - In AVA 4, you'll no longer be able to pass `null` as the expectation for `t.throws()` & `t.throwsAsync()`. You can opt in to this early by enabling the `disableNullExpectations` experiment. Thanks [@​JSimoni42](https://togithub.com/JSimoni42)! [`f328a69`](https://togithub.com/avajs/ava/commit/f328a6933af7aca221b08f694bb14b03701eca68) - The Enzyme recipe has been updated. Thanks [@​jonathansamines](https://togithub.com/jonathansamines)! [`db5d2c3`](https://togithub.com/avajs/ava/commit/db5d2c369178b78dfbd899d002a141a05655ccdc) - The TypeScript recipe has been updated. Thanks [@​SephReed](https://togithub.com/SephReed)! [`a3379fa`](https://togithub.com/avajs/ava/commit/a3379fad3893468309a43b4b56d290f94933f082) See https://github.com/avajs/ava/compare/v3.12.1...v3.13.0 for all changes. ### [`v3.12.1`](https://togithub.com/avajs/ava/releases/v3.12.1) [Compare Source](https://togithub.com/avajs/ava/compare/v3.12.0...v3.12.1) #### Configure how AVA loads test files Normally, AVA loads all files as CommonJS, except for `mjs` files and if you've configured `"type": "module"` in your `package.json`. As an experiment, you can now configure how AVA loads other file extensions. This is useful if you want to use Node.js' [experimental loaders](https://nodejs.org/docs/latest/api/esm.html#esm_experimental_loaders) feature. Read more [in our documentation](https://togithub.com/avajs/ava/blob/master/docs/06-configuration.md#configuring-module-formats). Thank you [@​macarie](https://togithub.com/macarie) for working on this! [`5c9dbb9`](https://togithub.com/avajs/ava/commit/5c9dbb96ad0beb7521e5051390478493250ba6b0) #### Comparison bugfix There was a bug in our [comparison library](https://togithub.com/concordancejs/concordance) which meant that negative-index properties on lists were not compared. This was fixed in a patch release, which will definitely be installed when you install AVA 3.12. Your tests may have been passing, even though they should have been failing. They'll fail now. Snapshots may also be different, causing tests to fail. #### All changes See https://github.com/avajs/ava/compare/v3.11.1...v3.12.1 for all changes. Thank you [@​AnthumChris](https://togithub.com/AnthumChris) for making sure our ESM example used ESM syntax ([`20bc781`](https://togithub.com/avajs/ava/commit/20bc7810536b3b968db5461ff4093bb5ae912050)). ### [`v3.12.0`](https://togithub.com/avajs/ava/compare/v3.11.1...v3.12.0) [Compare Source](https://togithub.com/avajs/ava/compare/v3.11.1...v3.12.0) ### [`v3.11.1`](https://togithub.com/avajs/ava/releases/v3.11.1) [Compare Source](https://togithub.com/avajs/ava/compare/v3.11.0...v3.11.1) This release fixes corrupted output of the default reporter when test or program code writes to standard out. [`5ddc9fd`](https://togithub.com/avajs/ava/commit/5ddc9fda100205a5ca315a86e27a01be443b88b1) Also, thanks to [@​jonathansamines](https://togithub.com/jonathansamines) we've taken another step to using AVA to test AVA. [`1150991`](https://togithub.com/avajs/ava/commit/1150991ba1921cbf888438d46350894484356078) See https://github.com/avajs/ava/compare/v3.11.0...v3.11.1 for all changes. ### [`v3.11.0`](https://togithub.com/avajs/ava/releases/v3.11.0) [Compare Source](https://togithub.com/avajs/ava/compare/v3.10.1...v3.11.0) #### New `t.like()` assertion Thanks to [@​futpib](https://togithub.com/futpib) we now have a `t.like()` assertion [`19c4f35`](https://togithub.com/avajs/ava/commit/19c4f35fbae740268dedeeb4d450f813f2d5e85e): In the following example, the `map` property of `value` must be deeply equal to that of `selector`. However `nested.qux` is ignored, because it's not in `selector`. ```js t.like({ map: new Map([['foo', 'bar']]), nested: { baz: 'thud', qux: 'quux' } }, { map: new Map([['foo', 'bar']]), nested: { baz: 'thud', } }) ``` Read more in the [`t.like()` assertion documentation](https://togithub.com/avajs/ava/blob/master/docs/03-assertions.md#likevalue-selector-message). This assertion was [previously introduced](https://togithub.com/avajs/ava/releases/tag/v3.9.0) as an experiment. #### VSCode 1.47 debugging improvements You can now debug tests using the new JavaScript Debug Terminal in VSCode 1.47. We've updated our [debugging recipe](https://togithub.com/avajs/ava/blob/master/docs/recipes/debugging-with-vscode.md) accordingly. Thank you [@​connor4312](https://togithub.com/connor4312) for the documentation updates and your work on VSCode! [`bc39bcc`](https://togithub.com/avajs/ava/commit/bc39bcc3ff92cb2979564ec2e69dc72be6509f78) #### All changes See https://github.com/avajs/ava/compare/v3.10.1...v3.11.0 for all changes. ### [`v3.10.1`](https://togithub.com/avajs/ava/releases/v3.10.1) [Compare Source](https://togithub.com/avajs/ava/compare/v3.10.0...v3.10.1) ### It's time for another AVA release 🎉 #### Restricting when you can update snapshots When executing a subset of tests, through `--match` or or `.only()` or `.skip()`, you can no longer *also* update snapshots. This prevents you from accidentally deleting snapshots. Thank you [@​bunysae](https://togithub.com/bunysae) for putting this together. [`f72fab4`](https://togithub.com/avajs/ava/commit/f72fab40160a413f4d7ab0208979fe3e721198ea) If you are skipping a test that you can't immediately fix, but you still need to update snapshots, use `.failing()` instead. #### Support for message strings in `t.timeout()` calls Thanks to [@​jonathansamines](https://togithub.com/jonathansamines) you can now provide a message string when using `t.timeout()`. This can be useful if your test depends on some other setup that may not have been completed: [`ca8ea45`](https://togithub.com/avajs/ava/commit/ca8ea45587ebefa5584d6a7aa50adf90840701cf) ```js test('foo', t => { t.timeout(100, 'make sure database has started'); // Write your assertions here }); ``` #### `t.try()` does not work in hooks `t.try()` has never worked in hooks, but thanks to [@​okyantoro](https://togithub.com/okyantoro) it now fails properly instead of crashing. [`d01db61`](https://togithub.com/avajs/ava/commit/d01db61ee5e9785d9f80ad5683cac21db4b96509) #### `t.snapshot()` does not really work in hooks either `t.snapshot()` sort of works in hooks, but we'll be removing this in AVA 4. You can opt in to this behavior by enabling the `disableSnapshotsInHooks` experiment. Again thank you [@​okyantoro](https://togithub.com/okyantoro) [`d01db61`](https://togithub.com/avajs/ava/commit/d01db61ee5e9785d9f80ad5683cac21db4b96509). #### Fixed TypeScript definition for `t.like()` The [experimental `t.like()` assertion](https://togithub.com/avajs/ava/issues/2518) should now work better with TypeScript. #### All changes See https://github.com/avajs/ava/compare/v3.9.0...v3.10.1 for all changes. ### [`v3.10.0`](https://togithub.com/avajs/ava/compare/v3.9.0...v3.10.0) [Compare Source](https://togithub.com/avajs/ava/compare/v3.9.0...v3.10.0) ### [`v3.9.0`](https://togithub.com/avajs/ava/releases/v3.9.0) [Compare Source](https://togithub.com/avajs/ava/compare/v3.8.2...v3.9.0) ##### New experiments! Thanks to [@​futpib](https://togithub.com/futpib) we now have an experimental `t.like()` assertion [`19c4f35`](https://togithub.com/avajs/ava/commit/19c4f35fbae740268dedeeb4d450f813f2d5e85e): In the following example, the `map` property of `value` must be deeply equal to that of `selector`. However `nested.qux` is ignored, because it's not in `selector`. ```js t.like({ map: new Map([['foo', 'bar']]), nested: { baz: 'thud', qux: 'quux' } }, { map: new Map([['foo', 'bar']]), nested: { baz: 'thud', } }) ``` Read more in the [`t.like()` assertion documentation](https://togithub.com/avajs/ava/blob/master/docs/03-assertions.md#likevalue-selector-message) and [let us know what you think](https://togithub.com/avajs/ava/issues/2518). [@​yjpa7145](https://togithub.com/yjpa7145) has contributed an experiment to reverse the order in which `t.teardown()` functions are run, so that the last registered function is called first [`952a017`](https://togithub.com/avajs/ava/commit/952a0177758c5601a72c2b050fc0308e7fa774c7). This will be the behavior in AVA 4. To enable both these experiments update your AVA configuration: **`package.json`**: ```json { "ava": { "nonSemVerExperiments": { "likeAssertion": true, "reverseTeardowns": true } } } ``` **`ava.config.js`**: ```js export default { nonSemVerExperiments: { likeAssertion: true, reverseTeardowns: true } } ``` ##### Reporter changes [@​Michael55555](https://togithub.com/Michael55555) has helped us combine our reporter code into a single file [`b3866b6`](https://togithub.com/avajs/ava/commit/b3866b6b06c98862a19f6cb27ec28b643e2f00c7). We've also made some other tweaks and improvements [`baaf99a`](https://togithub.com/avajs/ava/commit/baaf99a792eed586678a0cf88864f3f0aa16bd7a). Let us know if anything seems amiss. ##### Improved diffs [@​bunysae](https://togithub.com/bunysae) made it so that missing or extraneous objects in diffs are printed with extra depth [https://github.com/concordancejs/concordance/pull/62](https://togithub.com/concordancejs/concordance/pull/62). ##### Farewell Node.js 13 Node.js 13 has reached end-of-life. Per our [support statement](https://togithub.com/avajs/ava/blob/master/docs/support-statement.md) we have removed it from our test matrix and supported version list. ##### All changes See https://github.com/avajs/ava/compare/v3.8.2...v3.9.0 for all changes. Thank you [@​paulrobertlloyd](https://togithub.com/paulrobertlloyd) and [@​Autre31415](https://togithub.com/Autre31415) for contributing documentation improvements. ### [`v3.8.2`](https://togithub.com/avajs/ava/releases/v3.8.2) [Compare Source](https://togithub.com/avajs/ava/compare/v3.8.1...v3.8.2) - Fix bad dependency [`fd92b4a`](https://togithub.com/avajs/ava/commit/fd92b4a3) - Use configured depth limit for diffs in assertion failures, thanks [@​bunysae](https://togithub.com/bunysae)! [`a5385a4`](https://togithub.com/avajs/ava/commit/a5385a41) ### [`v3.8.1`](https://togithub.com/avajs/ava/releases/v3.8.1) [Compare Source](https://togithub.com/avajs/ava/compare/v3.8.0...v3.8.1) #### Node.js 14 support Great news, this is a feature heavy release! First off, though, AVA now officially supports Node.js 14. Thank you [@​zackschuster](https://togithub.com/zackschuster)! [`2e7c76b`](https://togithub.com/avajs/ava/commit/2e7c76b85cb65a04605fed843ee2f571afc66c37) #### Run tests at specific line numbers AVA can now run tests at specific line numbers! 🎉 Given the following test file: `test.js` ```js 1: test('unicorn', t => { 2: t.pass(); 3: }); 4: 5: test('rainbow', t => { 6: t.fail(); 7: }); ``` Running `npx ava test.js:2` for would run the `unicorn` test. In fact you could use any line number between `1` and `3`. This feature is only available from the command line. It won't work if you use tools like `ts-node/register` or `@babel/register`, and it does not currently work with `@ava/babel` and `@ava/typescript`. See [https://github.com/avajs/ava/issues/2473](https://togithub.com/avajs/ava/issues/2473). Thank you [@​ulken](https://togithub.com/ulken) for your hard work and patience to get this shipped. [`1222ce9`](https://togithub.com/avajs/ava/commit/1222ce9538e4890c20af695e558e3ee490f5a41b) #### Test-specific teardown functions Sometimes tests have side-effects you want to clean up. [@​ulken](https://togithub.com/ulken) has implemented `t.teardown()` which lets you register teardown functions *within* your test. They'll run once your test has finished, even if it failed: [`75cbc3b`](https://togithub.com/avajs/ava/commit/75cbc3b2a53d3b8530266b10bed71b838bc11fec) test('read file', t => { fs.writeFileSync('file.txt', '👋'); t.teardown(() => fs.unlinkSync('file.txt'); // Run assertions }); #### Node.js internal in stack traces Thanks to [@​bunysae](https://togithub.com/bunysae), stack traces now include Node.js internals. Previously we removed them because we wanted you to focus on your own code, but quite often they do provide context. Now they're displayed, but somewhat dimmed. [`9a9351d`](https://togithub.com/avajs/ava/commit/9a9351ddbee9c6c76601210c5dd8f5b0d81cc3b0) #### Watch mode with the default reporter Watch mode with the default reporter once again accepts key input. Thanks [@​pcdevil](https://togithub.com/pcdevil)! [`59c227d`](https://togithub.com/avajs/ava/commit/59c227d9c5261117d99e8e84693b9c89c3438a92) #### ICYMI - `afterEach()` and `afterEach.always()` hooks can now determine whether the test passed. Thank you [@​bunysae](https://togithub.com/bunysae) for contributing this! [`8f312c0`](https://togithub.com/avajs/ava/commit/8f312c0) ```js test('passes', t => t.pass()); test.afterEach(t => { if (t.passed) { // Do something because the test passed } else { // Do something because the test failed } }); ``` - If you've ever wanted to save some files along with AVA's snapshots, you can now determine the directory path by accessing `test.meta.snapshotDirectory`.

Thanks to [@​DYefimov](https://togithub.com/DYefimov) for contributing this! [`13d6651`](https://togithub.com/avajs/ava/commit/13d66519) See https://github.com/avajs/ava/compare/v3.4.0...v3.5.0 for all changes. Spoiler alert: it's just this one 😉 ### [`v3.4.0`](https://togithub.com/avajs/ava/releases/v3.4.0) [Compare Source](https://togithub.com/avajs/ava/compare/v3.3.0...v3.4.0) #### Introducing the `t.try()` assertion The new `t.try()` allows you to *try* assertions without causing the test to fail: ```js test('do the thing', async t => { const attempt = () => t.try(async tt => { const result = await getResult() // getResult() can be flaky and sometimes throws :( tt.is(result, 'expected') }) const firstAttempt = await attempt() if (firstAttempt.passed) return firstAttempt.commit() t.log('Retrying (just once)') firstAttempt.discard() const secondAttempt = await attempt() secondAttempt.commit() }) ``` You can use any test implementation with `t.try()`, including (arrays of) [macros](https://togithub.com/avajs/ava/blob/master/docs/01-writing-tests.md#reusing-test-logic-through-macros). You can decide what to do with attempts. You can even run attempts concurrently, so long as they don't use snapshot assertions. This is great building block for handling all kinds of advanced test scenarios. We can't wait to see what you'll do with it! Find out more in the [assertion documentation](https://togithub.com/avajs/ava/blob/master/docs/03-assertions.md#trytitle-implementation--macro--macro-args). This feature was previously behind an experimental flag. That flag has now been removed. If you have enabled the flag you'll have to update your AVA config. Also note that as of this release, attempt titles are always prefixed with the title of the parent test [`7ee3a0e`](https://togithub.com/avajs/ava/commit/7ee3a0e5940a105dec447851c777ea44555e8220). Once again, thank you [@​qlonik](https://togithub.com/qlonik) for contributing this new assertion. #### In case you missed it: ESM support As of the [3.3.0](https://togithub.com/avajs/ava/releases/tag/v3.3.0) release, AVA can load ESM test files! Check our updated [ES Modules recipe](https://togithub.com/avajs/ava/blob/master/docs/recipes/es-modules.md) for details. Our ESM support is still incomplete. Progress is tracked in the [ESM support project](https://togithub.com/orgs/avajs/projects/2). Join us, won't you? #### Other changes - The `t.throws()` and `t.throwsAsync()` assertions can now be called with `undefined` as the second argument. Previously, if you wanted to set an assertion message but did not want to provide any expectations for the thrown error you had to pass `null`. That's still allowed, of course.

[`@ava/typescript`]: https://togithub.com/avajs/typescript #### Other changes Thanks to [@​jhechtf](https://togithub.com/jhechtf) for fixing our TypeScript recipe after the changes in AVA 3.0 [`91a0086`](https://togithub.com/avajs/ava/commit/91a00864f7f113dd63a2c4ecc383fc8c45f79665) See https://github.com/avajs/ava/compare/v3.0.0...v3.1.0 for all changes. ### [`v3.0.0`](https://togithub.com/avajs/ava/releases/v3.0.0) [Compare Source](https://togithub.com/avajs/ava/compare/v2.4.0...v3.0.0) ### We're proud to introduce AVA 3! 🚀 When we began AVA, JavaScript was very different. Most syntax you find familiar today was not supported by Node.js. Instead we relied on [Babel](https://babeljs.io/) to support that syntax before it made its way to Node.js itself. These days most new [stage-4](https://togithub.com/tc39/proposals/blob/master/finished-proposals.md) syntax is adopted quickly. It's often not necessary to transpile anything. Therefore we're removing our built-in Babel support from AVA itself. Without Babel you'll have to resort to using `require()` functions in your JavaScript files. But, you say, [Node.js 13 supports ECMAScript Modules](https://nodejs.org/api/esm.html)! Well, we're getting there. For a start, AVA now also looks for `.cjs` files. And `.mjs` files are recognized too, but can't be loaded just yet. This also impacts `ava.config.js` files. If you'd like to help out delivering full `.mjs` support check out the issues in the [ESM support project](https://togithub.com/orgs/avajs/projects/2). Removing Babel allowed us to simplify how test files are selected. Likely non-test files, inside "fixture" or "helper" directories are ignored. The same for files that are inside an underscore-prefixed directory. We've made some other breaking changes in this area so please do read the full release notes. You can again pass glob patterns on the CLI. However these now filter the test files that AVA already selected based on the configuration. In other words you can't run files that wouldn't be run by invoking `npx ava`. AVA now interrupts your tests if there's no progress for 10 seconds. Use the `timeout` configuration or `--timeout` CLI option to change this. #### New features ##### Built-in debug mode You can now debug individual test files using the V8 Inspector: ```console npx ava debug test.js ``` Connect to the debugger with [Chrome DevTools](https://togithub.com/avajs/ava/blob/master/docs/recipes/debugging-with-chrome-devtools.md). Or [set up a debugger in VSCode](https://togithub.com/avajs/ava/blob/master/docs/recipes/debugging-with-vscode.md). ##### Configurable Node.js arguments You can now configure the arguments passed to Node.js itself when AVA starts its worker processes. Use the `nodeArguments` configuration or combine with the `--node-arguments` CLI option. #### All breaking changes ##### Supported Node.js versions We now support Node.js 10, 12 and 13. The minimal versions are 10.18.0, 12.14.0 and 13.5.0 respectively. ##### Removing Babel Utilize Babel with AVA by installing our [`@ava/babel`](https://togithub.com/avajs/babel) package and then enabling Babel by setting `babel: true` in the AVA configuration. Having this as a separate package means it can evolve independently. The `compileEnhancements` setting has been moved into the `babel` configuration. Consequently, the `t.assert()` assertion will only print its detailed information when you use Babel. And we won't be able to catch typical mistakes with `t.throws()` as well as we could before. The `ava/stage-4` preset is now available from `@ava/babel/stage-4`. Our old `@ava/babel-preset-transform-test-files` and `@ava/babel-preset-stage-4` packages are no longer maintained and not installed with AVA itself. ##### ECMAScript Module Support AVA now also looks for `.cjs` and `.mjs` test files. That said, `.mjs` files cannot be loaded just yet. Also, when you add `"type": "module"` , AVA would really like to treat `.js` files as ECMAScript Modules, but can't just yet. Similarly,`ava.config.cjs` configuration files are now supported. `ava.config.mjs` files not just yet. With AVA 2, we loaded `ava.config.js` files using the [`esm`](https://www.npmjs.com/package/esm) package. To avoid confusion between the different module formats we now *only* support `export default` statements. No `import`, no `__filename`. Configuration files that have dependencies should be written as a `.cjs` file for now. Configuration files can only have `.cjs`, `.js` and `.mjs` extensions. The remaining work is tracked in the [ESM support project](https://togithub.com/orgs/avajs/projects/2). ##### File selection When you use the default configuration AVA will no longer select files matching the following glob patterns: - `**/__tests__/**/__helper__/**/*` - `**/__tests__/**/__helpers__/**/*` - `**/__tests__/**/__fixture__/**/*` - `**/__tests__/**/__fixtures__/**/*` - `**/test/**/helper/**/*` - `**/test/**/helpers/**/*` - `**/test/**/fixture/**/*` - `**/test/**/fixtures/**/*` - `**/tests/**/helper/**/*` - `**/tests/**/helpers/**/*` - `**/tests/**/fixture/**/*` - `**/tests/**/fixtures/**/*` Additionally, when a file has a parent directory that starts with a *single* underscore, it can never be a test file. `test.js` files are only selected if they're next to the `package.json` file, or inside top-level `src` and ` source `directories. We've removed the configuration of helpers. Previously, files selected by the `helpers` glob patterns were never considered test files. Now that this configuration is no longer supported you'll need to ensure the `files` patterns exclude your helper files. If you're using Babel, you can configure [the compilation of additional files](https://togithub.com/avajs/babel#compile-additional-files) . The `sources` configuration has also been removed. Instead, use the `ignoredByWatcher` configuration. Changes to files matched by these glob patterns will not cause the watcher to rerun tests. Negated `sources` patterns must be used without the negation in `ignoredByWatcher`: ```diff export default { - sources: ['!examples/**/*'] + ignoredByWatcher: ['examples/**/*'] } ``` ##### CLI changes Internally we've replaced [`meow`](https://www.npmjs.com/package/meow) by [`yargs`](https://www.npmjs.com/package/yargs). We're not expecting things to break because of this, but you never know. ##### Resetting the cache The `--reset-cache` argument has been replaced by a proper `reset-cache` command: ```console npx ava reset-cache ``` ##### File selection (again!) AVA again accepts glob patterns via the CLI: ```console npx ava '**/api/**/*' ``` The way this work is that AVA first finds all test files, according to the configuration, and then filters to select just the files that also match the glob patterns passed via the CLI. You can still pass paths to specific files: ```console npx ava src/api/test/my-api-test.js ``` However unlike with AVA 2, you can no longer specify test files that aren't already selected by AVA's configuration. ##### `t.throws()` and `t.throwsAsync()` assertions The second argument passed to these assertions must now be an `expectation` object. You can no longer pass the expected constructor, error message or regular expression. ##### Other breaking changes - Support for old [`esm`](https://www.npmjs.com/package/esm) versions has been removed. - We've set a default test timeout of 10 seconds. This means that if no test results are received for 10 seconds, AVA forces its worker processes to quit. - The `NODE_PATH` environment variable is no longer rewritten to ensure values are absolute paths. - AVA longer fakes the TTY in worker processes. #### Other changes - We've simplified how we identify observables. Any object returned by a test implementation that has a `subscribe` function is assumed to be an observable. AVA's type definition has been updated accordingly. - The TAP reporter now reports hook failures as test failures. - We've added an example of [module path mapping to our TypeScript recipe](https://togithub.com/avajs/ava/blob/master/docs/recipes/typescript.md#using-module-path-mapping). - We've added a [Selenium WebDriver JS recipe](https://togithub.com/avajs/ava/blob/master/docs/recipes/testing-with-selenium-webdriverjs.md). #### All changes #### Thanks Thank you [@​tymfear](https://togithub.com/tymfear), [@​HeathNaylor](https://togithub.com/HeathNaylor), [@​grnch](https://togithub.com/grnch), [@​alexdrans](https://togithub.com/alexdrans), [@​MoppetX](https://togithub.com/MoppetX), [@​jimmywarting](https://togithub.com/jimmywarting), [@​micaelmbagira](https://togithub.com/micaelmbagira), [@​aptester](https://togithub.com/aptester), [@​theashraf](https://togithub.com/theashraf), [@​sramam](https://togithub.com/sramam) and [@​maximelkin](https://togithub.com/maximelkin).

All kinds of interesting things can be built on top of this, from fuzzy testers to new test interfaces and more. We're excited to get this out there, but it's not quite done yet. For now you have to [*opt in*](https://togithub.com/avajs/ava/blob/master/docs/06-configuration.md#experiments) to this new feature. Being opt-in, we may make changes (breaking ones even!) until we feel this is stable. To opt in, configure AVA with the following: `package.json`: ```json { "ava": { "nonSemVerExperiments": { "tryAssertion": true } } } ``` `ava.config.js`: ```js export default { nonSemVerExperiments: { tryAssertion: true } }; ``` We'd love to hear your feedback. Please join us in this issue: [https://github.com/avajs/ava/issues/2250](https://togithub.com/avajs/ava/issues/2250) Also, if you're looking to help out with the remaining issues so that we can ship this *without* the opt-in, have a look at this project: https://github.com/orgs/avajs/projects/1 Thanks again [@​qlonik](https://togithub.com/qlonik)! #### Other changes - We've added the [common pitfall](https://togithub.com/avajs/ava/blob/master/docs/08-common-pitfalls.md) of sharing variables across asynchronous tests [`49b202f`](https://togithub.com/avajs/ava/commit/49b202fb5c376e71c1400f6c35043280cf417140) - We've updated the [endpoint testing recipe](https://togithub.com/avajs/ava/blob/master/docs/recipes/endpoint-testing.md) to focus on the concept, not specific libraries [`67e4dea`](https://togithub.com/avajs/ava/commit/67e4deac2857503e5fac7d38da2d23014eb29724) #### All changes [`v2.3.0...v2.4.0`](https://togithub.com/avajs/ava/compare/v2.3.0...v2.4.0) #### Thanks Thank you [@​jeremenichelli](https://togithub.com/jeremenichelli), [@​jamesgeorge007](https://togithub.com/jamesgeorge007), [@​dongjae93](https://togithub.com/dongjae93), [@​qlonik](https://togithub.com/qlonik) and [@​tryzniak](https://togithub.com/tryzniak).

[`b27cb8d`](https://togithub.com/avajs/ava/commit/b27cb8d538c58743ba3f5d46e0523e7a0ca5982c) - TTY in the worker processes should follow the new APIs in Node.js 12.7.0 (when used with those Node.js versions). [`7dcb473`](https://togithub.com/avajs/ava/commit/7dcb473d90d9415c691da90df75a0452d846cc29) - AVA now handles stage-4 syntax like dynamic import, and stage-3 syntax like BigInt, numeric separators and class properties that are supported by V8. [`9baca8c`](https://togithub.com/avajs/ava/commit/9baca8ca4dcbf9512c1f7a33adaeedd37fc8eda2) - AVA now supports dynamic import through our [stage-4](https://togithub.com/avajs/babel-preset-stage-4) preset. - AVA now uses [`import-local@^3.0.2`](https://togithub.com/sindresorhus/import-local/releases/tag/v3.0.2) which fixes issues with Lerna projects. - **For our TypeScript users**, we've changed the default type of `t.context` to `unknown`, [in line with TypeScript's changes in their 3.5 release](https://devblogs.microsoft.com/typescript/announcing-typescript-3-5/).

Consequently we've removed support in AVA. We are now testing with Node.js 12 though. [`3a4afc6`](https://togithub.com/avajs/ava/commit/3a4afc6cf35aeffb6b019c6b75fa9b8e071bb53d) ##### Test file and helper selection We've been working on simplifying how test files and helpers are selected. First off, the `files` option now only accepts glob patterns. If you configured it with directories before, please add `/**/*` to get the previous behavior. The `files` and `sources` options must now be arrays containing at least one pattern. It's no longer possible to override a default exclusion pattern, but [we're looking at making these configurable separately](https://togithub.com/avajs/ava/issues/2106). AVA used to treat all files inside a `helpers` directory as test helpers. Finding these files could be really slow, however, and it also meant you couldn't have tests inside a `helpers` directory. Instead you can now specify glob paterns to find these helpers: ```json { "ava": { "helpers": [ "**/helpers/**/*" ] } } ``` Test files starting with an underscore are still recognized as helpers. Files inside `fixtures` directories are no longer ignored, and will now be treated as test files. The watcher now also watches `ava.config.js` files. AVA now also selects files ending with `.spec.js` when looking for tests, as well as looking in `tests` directories. [`08e99e5`](https://togithub.com/avajs/ava/commit/08e99e516e13af75d3ebe70f12194a89b610217c) [`b1e54b1`](https://togithub.com/avajs/ava/commit/b1e54b1a02ba7220571a06e4d324d460ea7ece54) The CLI now only takes file paths, not glob patterns. We'd [like some help updating our ESLint plugin](https://togithub.com/avajs/eslint-plugin-ava/issues/238) as well. ##### Snapshots in CI When you run tests locally and add a new snapshot, AVA automatically updates the `.snap` file. However if you forget to commit this file and then run your CI tests, they won't fail because AVA quietly updates the `.snap` file, just like it does locally. With this release, AVA will fail the `t.snapshot()` assertion if it is run in CI and no snapshot could be found. [`0804107`](https://togithub.com/avajs/ava/commit/0804107b49ef3bb43656cd48d27b0d54ea080d71) ##### Assertion messages must be strings AVA now enforces assertion messages to be strings. The message is only used when the assertion fails, and non-string values may cause AVA to crash. You may see test failures if you were accidentally passing a non-string message. [`49120aa`](https://togithub.com/avajs/ava/commit/49120aafd40c96bbe8196d3da8898d05006588d8) ##### Flow type definitions We've decided to remove the Flow type definitions from AVA itself. We don't have anybody to maintain them and consequently they've become a blocker when adding features to AVA. [`c633cf0`](https://togithub.com/avajs/ava/commit/c633cf08891abaf7649d490642eef38b8150bfe0) We've set up a new repository from which we'll publish the definitions, but we need your help setting it up. If you use AVA and Flow, please join us in [https://github.com/avajs/flow-typed/issues/1](https://togithub.com/avajs/flow-typed/issues/1). ##### Observable typing Test implementations may return observables. We've updated our TypeScript definition to require these to have a `Symbol.observable` function. [`c2d8218`](https://togithub.com/avajs/ava/commit/c2d8218ba78b26fe1368df183924757cd27555e4) #### New features ##### Configurable printing depth AVA now uses the [`util.inspect.defaultOptions.depth`](https://nodejs.org/api/util.html#util_util_inspect_defaultoptions) option when printing objects, so you can configure the depth. [`98034fb`](https://togithub.com/avajs/ava/commit/98034fbb661bcc6cb882e1ae007a7877a803b3a4) ##### Specify environment variables in your AVA config You can now specify environment variables in your config, using the `environmentVariables` object. [`a53ea15`](https://togithub.com/avajs/ava/commit/a53ea157367c9cec91184cfbb226487c81229513) #### Other changes - We've added `UntitledMacro` and `UntitledCbMacro` types, for macro functions that will never have a `.title` function. Though really this just helped simplify the type definition. Thanks [@​qlonik](https://togithub.com/qlonik)! [`ebf4807`](https://togithub.com/avajs/ava/commit/ebf480779b826dcccc86376caf8ca5af4273e912) - The dependency tracking in watch mode now respects custom require hooks you install in the worker processes. Thanks [@​lo1tuma](https://togithub.com/lo1tuma)! [`cb4c809`](https://togithub.com/avajs/ava/commit/cb4c8095952a970fb9bf5d1620810d5e172080ae) - The TypeScript definition once again allows `test.skip(macro)` [`ba5cd80`](https://togithub.com/avajs/ava/commit/ba5cd804845517b1a5c4b04d1c08253ef27133d3) - AVA now exposes some methods to our [ESLint plugin](https://togithub.com/avajs/eslint-plugin-ava), allowing our plugin to support the new test & helper file selection. [`51433be`](https://togithub.com/avajs/ava/commit/51433bed947d31e5f3df26bdf6eee10ad4344efa) #### All changes [`v1.4.1...v2.0.0`](https://togithub.com/avajs/ava/compare/v1.4.1...v2.0.0) #### Thanks Thank you [@​StoneCypher](https://togithub.com/StoneCypher), [@​LukasHechenberger](https://togithub.com/LukasHechenberger), [@​lo1tuma](https://togithub.com/lo1tuma), [@​htor](https://togithub.com/htor), [@​alexisfontaine](https://togithub.com/alexisfontaine) and [@​grnch](https://togithub.com/grnch). We couldn't have done this without you! #### Get involved We welcome new contributors. AVA is a friendly place to get started in open source. We have a [great article](https://medium.com/@​vadimdemedes/making-your-first-contribution-de6576ddb190#.umxr7id07) on getting started contributing and a comprehensive [contributing guide](https://togithub.com/avajs/ava/blob/master/contributing.md). ### [`v1.4.1`](https://togithub.com/avajs/ava/releases/v1.4.1) [Compare Source](https://togithub.com/avajs/ava/compare/v1.4.0...v1.4.1) #### Focusing [`power-assert`](https://togithub.com/power-assert-js/power-assert) AVA comes with [`power-assert`](https://togithub.com/power-assert-js/power-assert) built-in, giving you more descriptive assertion messages. However it's been confusing to understand *which* assertions come with `power-assert`. To address this we've added the new `t.assert()` assertion. It's now the only assertion that is `power-assert` enabled. The assertion passes if called with a truthy value. Consider this example: ```js test('enhanced assertions', t => { const a = /foo/; const b = 'bar'; const c = 'baz'; t.assert(a.test(b) || b === c); }); ```
AVA will output: 
6:   const c = 'baz';
7:   t.assert(a.test(b) || b === c);
8: });

Value is not truthy:

false

a.test(b) || b === c
\=> false

b === c
\=> false

c
\=> 'baz'

b
\=> 'bar'

a.test(b)
\=> false

b
\=> 'bar'

a
\=> /foo/
Our [ESLint plugin](https://togithub.com/avajs/eslint-plugin-ava) has been updated to support this new assertion. Many thanks to [@​eemed](https://togithub.com/eemed) for implementing this! [`9406470`](https://togithub.com/avajs/ava/commit/94064702837583f1cd3920142c5d0ce50e71e255) #### Watch mode Watch mode now prints the available commands. Thanks [@​KompKK](https://togithub.com/KompKK)! [`cd256ac`](https://togithub.com/avajs/ava/commit/cd256ac53c975d51ddabd3d80a9f909424f5d7e3) #### Bug fixes - Filtered tests (when using `--match`, `.skip()` or `.only()`) are no longer included in the list of pending tests when timeouts occur or when you interrupt a test run. Thanks [@​vancouverwill](https://togithub.com/vancouverwill)! [`23e302a`](https://togithub.com/avajs/ava/commit/23e302a8dc35d03ba82916bd6591822a28d499d1) - We're now shimming all TTY methods in the worker processes, thanks to [@​okyantoro](https://togithub.com/okyantoro). [`c1f6fdf`](https://togithub.com/avajs/ava/commit/c1f6fdfed61c99c1144cff56b58d113810c630c8) #### Documentation updates - We've added a note to say that, by default, AVA does not have a default test timeout. Thanks [@​amokmen](https://togithub.com/amokmen)! [`99a10a1`](https://togithub.com/avajs/ava/commit/99a10a16a3e3037326c91fb23c2a052acd3abef9) #### All changes [`v1.3.1...v1.4.1`](https://togithub.com/avajs/ava/compare/v1.3.1...v1.4.1) #### Thanks Thank you [@​eemed](https://togithub.com/eemed), [@​KompKK](https://togithub.com/KompKK), [@​vancouverwill](https://togithub.com/vancouverwill), [@​okyantoro](https://togithub.com/okyantoro) and [@​amokmen](https://togithub.com/amokmen).

If you'd set a `code` expectation to a number we never actually *checked* that the thrown error had such a code! Thanks to [@​qlonik](https://togithub.com/qlonik) for both spotting and fixing this. [`82daa5e`](https://togithub.com/avajs/ava/commit/82daa5e373ef0587693927acc63ce5590e8d8eb2) - 1.2.0 contained a regression which meant that if you [faked](https://www.npmjs.com/package/lolex) `clearTimeout()`, you'd break AVA. That's now been fixed. [`40f331c`](https://togithub.com/avajs/ava/commit/40f331c27e70690e724f9ddc893fed0556058987) - Snapshot files are now recognized as source files, so if you're using watch mode and you delete one, AVA won't rerun *all* your test files. [`d066f6f`](https://togithub.com/avajs/ava/commit/d066f6fbc06ab2fa2d391ff373f5f09b2585b900) #### New features You can now use `require()` in `ava.config.js` files to load non-ES modules. [`334e15b`](https://togithub.com/avajs/ava/commit/334e15b4af06492c9aed2800a0764f245d6a908b) #### All changes [`v1.2.1...v1.3.1`](https://togithub.com/avajs/ava/compare/v1.2.1...v1.3.1) #### Thanks Thank you [@​itaisteinherz](https://togithub.com/itaisteinherz), [@​jdalton](https://togithub.com/jdalton), [@​kagawagao](https://togithub.com/kagawagao), [@​KompKK](https://togithub.com/KompKK), [@​SleeplessByte](https://togithub.com/SleeplessByte), [@​Chrisyee22](https://togithub.com/Chrisyee22) and [@​qlonik](https://togithub.com/qlonik) for helping us with this release.

In very large projects, the options send to worker processes would exceed limits on process argument size. We're now sending the options via the inter-process communication channel. [`3078892`](https://togithub.com/avajs/ava/commit/3078892236c4f78409cc8475ed88f07d1141c0f0) #### All changes 📚 [`v1.2.0...v1.2.1`](https://togithub.com/avajs/ava/compare/v1.2.0...v1.2.1) #### Get involved ✌️ We welcome new contributors. AVA is a friendly place to get started in open source.

The test will fail if this timeout is exceeded. The timeout is reset each time an assertion is made: ```js test('foo', t => { t.timeout(100); // 100 milliseconds // Write your assertions here }); ``` [`b65c6d7`](https://togithub.com/avajs/ava/commit/b65c6d7da8ba3c7274f36dbcbcff26485f27d36f) AVA also has a global [timeout feature](https://togithub.com/avajs/ava/blob/master/docs/07-test-timeouts.md). The mini reporter now logs tests that were pending when those timeouts occur. Additionally, if you interrupt a test using ctrl+c we'll now also show the pending tests. [`2b60556`](https://togithub.com/avajs/ava/commit/2b60556360bb3b434ee5b4bb3486acb8a32b7aa7) Thank you [@​dflupu](https://togithub.com/dflupu) for your hard work on this! #### Bug fixes and other improvements - We're no longer truncating multi-line error messages [`72e0762`](https://togithub.com/avajs/ava/commit/72e0762d9accb937b7b32f9151fe4088d194c710) - Unexpected errors in the throws assertions are now reported with the correct stack trace [`ad087f2`](https://togithub.com/avajs/ava/commit/ad087f250fe22878ab40f7855a079cf005818464) - The [Debugging with VSCode](https://togithub.com/avajs/ava/blob/master/docs/recipes/debugging-with-vscode.md) recipe has been update
