environment variable has not already been set. 42e7c74
Snapshots are stored alongside your test files. This is great when your test file is executed directly but say if you're using TypeScript to precompile your test file AVA would store the snapshots in your build directory. In this release, if source maps are available, AVA determines the original test file location and uses that to store the snapshots.
You can also specify where snapshots are stored through the snapshotLocation
option in the package.json
file. 7fadc34

Update to this version instead π
This is a pretty small release, but a great one if you're solely developing for Node.js 8.3 or above.
You can now use object rest/spread properties in test files without any further Babel configuration. Note that if you're running tests on older versions of Node.js you'll still need to add the relevant Babel plugins, since this new language feature has not yet reached stage 4. 37c9122

ava was updated from 0.20.0
to 1.0.1
.Update to this version instead π
Back in January we started work on the 1.0 release, taking the opportunity to upgrade to Babel 7 and follow its beta releases. It's been a year where we made massive improvements to AVA. It's also been a year with many exciting events in our personal lives. Be it honeymoons & weddings, work & friends, naturalizations and international relocations.
So, we're done. Or, rather, we're just beginning. Testing can be a drag. AVA helps you get it done. Its concise API, detailed error output, embrace of new language features and process isolation let you write tests more effectively. So you can ship more awesome code or do non-programming things.
Starting now we'll push out patches and new features more regularly. And, when the time comes, ship a 2.0 and a 3.0 and so forth. If you like what we're doing, why not try and contribute? We're a friendly bunch and we could use your help to make AVA even better.
We couldn't have gotten here without the nearly one hundred people who've contributed more, and the many more who suggested improvements, reported bugs and provided feedback. And, of course, everyone who's used AVA. Thank you for your enthusiasm and support.
t.throws()
behavior & t.throwsAsync()
We've rewritten t.throws()
so it behaves better, has better error output and lets you write better tests:
You have a few ways of asserting that the exception is as designed. You can pass a second argument:
message
should be equal to it.message
should match it.The most exciting new feature though is that you can pass an expectation object. A combination of the following expectations is supported:
t.throws(fn, {code: 'ENOTFOUND'}) // err.code === 'ENOTFOUND'
t.throws(fn, {code: 9}) // err.code === 9
t.throws(fn, {instanceOf: SyntaxError}) // err instanceof SyntaxError
t.throws(fn, {is: expectedErrorInstance}) // err === expectedErrorInstance
t.throws(fn, {message: 'expected error message'}) // err.message === 'expected error message'
t.throws(fn, {message: /expected error message/}) // /expected error message/.test(err.message)
t.throws(fn, {name: 'SyntaxError'}) // err.name === 'SyntaxError'
This makes tests like these much easier to write:
// Old assertion
const err = t.throws(fn, TypeError)
t.is(err.message, 'Expected a string')
// New assertion
t.throws(fn, {
instanceOf: TypeError,
message: 'Expected a string'
})
We've removed promise support from t.throws()
and t.notThrows()
. Use the new t.throwsAsync()
and t.notThrowsAsync()
assertions instead. Support for observables has been removed completey.
The original behavior was both hard to explain and hard to express in Flow and TypeScript. Now, if you have a function that throws a synchronous error, use t.throws()
(or t.notThrows()
). If you have a promise that should reject, or an asynchronous function that should fail, use await t.throwsAsync()
(or await t.notThrowsAsync()
).
Generally speaking, you should be able to replace every occurence of await t.throws
with await t.throwsAsync
, and await t.notThrows
with await t.notThrowsAsync
. A transform file for jscodeshift is available in this Gist. Run it like:
$ npx jscodeshift -t https://gist.githubusercontent.com/novemberborn/c2cdc94020083a1cafe3f41e8276f983/raw/eaa64c55dfcda8006fc760054055372bb3109d1c/transform.js test.js
Change test.js
to a glob pattern that matches your test files. See the jscodeshift CLI usage documentation for further details.
Assertion methods are now bound to the test, meaning you can provide them as direct arguments to other functions. A contrived example:
const assertEach = (arr, assert) => {
arr.forEach(value => assert(value));
};
test('all are true', t => {
assertEach(getArray(), t.true);
});
Whilst not strictly assertions, t.plan()
and t.log()
are now also bound to the test.
As part of our Node.js 10 support you can now use BigInt
values in t.deepEqual()
and t.snapshot()
. Note that this is still a stage-3 proposal.
AVA now uses Babel 7, with support for babel.config.js
files. We'll automatically use your project's Babel configuration. Babel options must now be specified in a testOptions
object. This will allow us to add source related options in the future.
Our @ava/stage-4
preset is now accessible via ava/stage-4
. We've added transforms for the latest ES2018 features where available (and even an ES2019 one!). You can also disable ava/stage-4
entirely:
package.json
:
{
"ava": {
"babel": {
"testOptions": {
"presets": [
["ava/stage-4", false]
]
}
}
}
}
Or, you can disable just ES module compilation:
package.json
:
{
"ava": {
"babel": {
"testOptions": {
"presets": [
["ava/stage-4", {"modules": false}]
]
}
}
}
}
The powerAssert
option and command line flags have been removed. You can now disable AVA's test enhancements by setting compileEnhancements
to false
. You can also disable AVA's Babel pipeline entirely:
package.json
:
{
"ava": {
"babel": false,
"compileEnhancements": false
}
}
Hooks declared using test.serial
will now execute serially. Only one of those hooks will run at a time. Other hooks run concurrently. Hooks still run in their declaration order.
Note that concurrent tests run concurrently. This means that .beforeEach()
and .afterEach()
hooks for those tests may also run concurrently, even if you use test.serial
to declare them.
t.context
can now be used in .before
and .after
hooks.
AVA now forwards arguments, provided after an --
argument terminator, to the worker processes. Arguments are available from process.argv[2]
onwards.
npx ava test.js -- hello world
There's a new recipe on how to use this.
Previously AVA populated process.argv[2]
and process.argv[3]
with some undocumented internal values. These are no longer available.
The --no-cache
CLI flag has been replaced by a --reset-cache
command. The latter resets AVA's regular cache location. You can still disable the cache through the cache
configuration option.
npx ava --reset-cache
ava.config.js
You can now configure AVA through an ava.config.js
file. It must be placed next to the package.json
, and you mustn't have any "ava"
options in the package.json
file. Export the configuration as a default:
export default {
babel: {
extensions: ['js', 'jsx']
}
};
Or export a factory function:
export default ({projectDir}) => ({
babel: {
extensions: ['js', 'jsx']
}
});
Following our convention to use ES modules in test files, we're expecting ES modules to be used in the configuration file. If this is causing difficulties please let us know in #1820.
You can now tell AVA to run test files with extensions other than js
! For files that should be compiled using Babel you can specify babel.extensions
:
package.json
:
{
"ava": {
"babel": {
"extensions": ["js", "jsx"]
}
}
}
Or define generic extensions, e.g. for use with TypeScript:
package.json
:
{
"ava": {
"compileEnhancements": false,
"extensions": ["ts"],
"require": [
"ts-node/register"
]
}
}
Note that AVA still assumes test & helper files to be valid JavaScript. They're still precompiled to enable some AVA-specific enhancements. You can disable this behavior by specifying "compileEnhancements": false
.
Adding new snapshots no longer causes the Markdown files to become malformed. Snapshots are now consistent across operating systems. If you've previously generated snapshots on Windows, you should update them using this release.
We now support BigInt
and <React.Fragment>
in t.snapshot()
. We've also improved support for the Symbol.asyncIterator
well-known symbol. Unfortunately these changes are not backwards compatible. You'll need to update your snapshots when upgrading to this release.
We've improved how AVA builds snapshot files to better support precompiled projects. Say, if you compile your TypeScript test files using tsc
before running AVA on the build output. AVA will now use the source map to figure out the original filename and use that as the basis for the snapshot files. You'll have to manually remove snapshots generated by previous AVA versions.
The TypeScript and Flow definitions have been rewritten and much improved. The TypeScript recipe has been updated to reflect the changes, and there's a new Flow recipe too.
AVA recognizes TypeScript build errors when using ts-node/register
.
TypeScript now type-checks additional arguments used by macros. You must type the arguments used:
import test, {Macro} from 'ava'
const failsToParse: Macro<[Buffer]> = (t, input) => {
t.throws(parse(input))
}
failsToParse.title = (providedTitle = 'unexpected input') => `throws when parsing ${providedTitle}`
test('malformed', failsToParse, fs.readFileSync('fixtures/malformed.txt'))
test(failsToParse, '}') // β¬
οΈ fails to compile
require
configuration.--fail-fast
behavior has been improved. AVA now makes sure not to start new tests. Tests that are already running though will finish. Hooks will also be called. AVA now prints the number of skipped test files if an error occurs and --fail-fast
is enabled.ci-parallel-vars
package for a list of supported CI environments.assert
module in Node.js 10 no longer crashes.process.stderr
is now emulated in the worker processes.--verbose
.<React.Fragment>
can be used in t.deepEqual
.title
functions of macros now receive undefined
rather than an empty string if no title was given in the test declaration. This means you can use default parameters.We've published a statement with regards to which Node.js versions we intend to support. As of this release we're only supporting Node.js 6.12.3 or newer, 8.9.4 or newer, 10.0.0 or newer and 11.0.0 or newer. This does not include Node.js 7 and 9.
You can no longer do:
test(t => t.pass());
Instead all tests must have titles, and they must be unique within the test file:
test('passes', t => t.pass());
This makes it easier to pinpoint test failures and makes snapshots better too.
Note that AVA no longer infers a test title from a function name:
test(function myTest (t) {
t.pass();
});
AVA's various test modifiers (.serial
, .skip
) must now be used in the correct order:
.serial
must be used at the beginning, e.g. test.serial()
..only
and .skip
must be used at the end, e.g. test.skip()
. You cannot combine them..failing
must be used at the end, but can be followed by .only
and .skip
, e.g. test.cb.failing()
and test.cb.failing.only()
..always
can only be used after .after
and .afterEach
, e.g. test.after.always()
..todo()
is only available on test
and test.serial
. No further modifiers can be applied.You must declare all tests and hooks at once. This was always the intent but previously AVA didn't enforce it very well. Now, once you declare a test or hook, all other tests and hooks must be declared synchronously. However you can perform some asynchronous actions before declaring your tests and hooks.
test
exportWe're no longer exporting the test()
method as a named export. Where before you could use import {test} from 'ava'
, you should now write import test from 'ava'
.
Macros can generate a test title. Previously, AVA would call the title
function with an empty string if no title was given in the test declaration. Now, it'll pass undefined
instead. This means you can use default parameters. Here's an example:
import test from 'ava'
const failsToParse = (t, input) => {
t.throws(parse(input))
}
failsToParse.title = (providedTitle = 'unexpected input') => `throws when parsing ${providedTitle}`
test('malformed', failsToParse, fs.readFileSync('fixtures/malformed.txt'))
test(failsToParse, Buffer.from('}', 'utf8'))
This is a breaking change if you were concatenating the provided title, under the assumption that it was an empty string.
t.throws()
& t.notThrows()
Thrown exceptions (or rejection reasons) must now be error objects.
t.throws()
and t.notThrows()
no longer support observables or promises. For the latter, use await t.throwsAsync()
and await t.notThrowsAsync()
instead.
Generally speaking, you should be able to replace every occurence of await t.throws
with await t.throwsAsync
, and await t.notThrows
with await t.notThrowsAsync
. A transform file for jscodeshift is available in this Gist. Run it like:
$ npx jscodeshift -t https://gist.githubusercontent.com/novemberborn/c2cdc94020083a1cafe3f41e8276f983/raw/eaa64c55dfcda8006fc760054055372bb3109d1c/transform.js test.js
Change test.js
to a glob pattern that matches your test files. See the jscodeshift CLI usage documentation for further details.
Assertions can be skipped by using .skip
at the end of the assertion, e.g. t.deepEqual.skip()
. You can now safely skip snapshot tests, though not whilst updating snapshots.
t.ifError()
We've removed the t.ifError()
assertion. It worked the same as t.falsy()
, so if you were using it please switch to t.falsy()
instead.
The source
option has been renamed to sources
. This is now consistent with files
. AVA will exit with an error if it encounters the source
option.
We've also removed unintentional support for init
, watch
and updateSnapshot
options.
The "default"
and "inherit"
configuration values have been removed. Babel options must now be specified in a testOptions
object. This will allow us to add source related options in the future.
The powerAssert
option and command line flags have been removed. You can now disable AVA's test enhancements by setting compileEnhancements
to false
.
The Babel recipe has been updated with the latest details.
The TypeScript and Flow definitions have been rewritten. The definitions export different interfaces so you may need to update your test code as well.
TypeScript now type-checks additional arguments used by macros. You must type the arguments used.
Some other internals have changed. You shouldn't have been relying on these, though if you did we're interested in hearing about it so we can better support your use case.
t._test

, in favor of the plain esm
package.ava/stage-4

. The stdout

. AVA will insert linebreaks in process.stdout
after writing a chunk to process.stderr

command. The latter resets AVA's regular cache location. You can still disable the cache through the cache

Version 0.22.0 of ava just got published.
The version 0.22.0 is not covered by your current version range.
Without accepting this pull request your project will work just like it did before. There might be a bunch of new features, fixes and perf improvements that the maintainers worked on for you though.
I recommend you look into these changes and try to get onto the latest version of ava. Given that you have a decent test suite, a passing build is a strong indicator that you can take advantage of these changes by merging the proposed change into your project. Otherwise this branch is a great starting point for you to work on the update.
Release Notes
0.22.0There's but a few commits in this release, but we've made a big change to how AVA manages its test workers π©πΌβπ¬π¨πΌβππ¨πΏβππ¨π»ββοΈπ©π½βπΌ.
Highlights
Default concurrency
We now cap the number of concurrent workers to the number of CPU cores on your machine. Previously AVA started workers for each test file, so if you had many test files this could actually bring things to a halt. 465fcec
You can still customize the concurrency by setting the
concurrency
option in AVA'spackage.json
configuration, or by passing the--concurrency
flag. We've also beefed up input validation on that flag. b6eef5aUnfortunately this does change how
test.only()
behaves. AVA can no longer guarantee that normal tests won't run. For now, if you want to usetest.only()
, you should run tests from just that file. We have an open issue to add an--only
flag, which will ensure that AVA runs just thetest.only()
tests. If you'd like to help us with that please head on over to #1472.t.log()
We've also added
t.log()
, which lets you print a log message contextually alongside the test result, instead of immediately printing it tostdout
