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 to support that syntax before it made its way to Node.js itself.
These days most new stage-4 syntax is adopted quickly. It's often not necessary to transpile anything. Therefore we're removing our built-in Babel support from AVA itself.
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.
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:
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 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 Our old @ava/babel-preset-transform-test-files and @ava/babel-preset-stage-4 packages are no longer maintained and not installed with AVA itself.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.
