    Experimental t.try() assertions

    ✅ Thanks to the amazing work and patience of @qlonik we're shipping a new assertion! t.try() lets you perform assertions and decide whether to commit or discard their outcome. 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 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:

    { "ava": { "nonSemVerExperiments": { "tryAssertion": true } } }
    

    ava.config.js:

    export default { nonSemVerExperiments: { tryAssertion: true } };
    

    We'd love to hear your feedback. Please join us in this issue: #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!

    🔄 Changes

    • 🛠 We've fixed some bugs to improve watch mode. ffa62ce 9e8d28f
    • ✅ AVA now prints an error when it receives non-existent test files on the command line. f01d05f
    • ✅ When using the TAP reporter, remaining tests are now included in failed test count. Failed hooks are no longer treated as test failures, and logs are printed. 8628976
    • 🖨 Internal errors that may occur for some edge cases are now printed. b27cb8d
    • 👷 TTY in the worker processes should follow the new APIs in Node.js 12.7.0 (when used with those Node.js versions). 7dcb473
    • 👍 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
    • 👍 AVA now supports dynamic import through our stage-4 preset.

  • v2.2.0

    July 08, 2019

    ✨ Enhancements

    ✅ You can now specify an alternative config file, using the --config CLI argument. This is useful if you want to run unit tests separately from integration tests, since you can have a config file specific to your integration tests which specifies different glob patterns. 2dae2bf

    🐛 Bug fixes

    ✅ We're now faking the new hasColors() method for better compatibility with Node.js 12. d399797

    Node.js 11

    ⬆️ We've removed Node.js 11 from our test matrix. You should upgrade to Node.js 12. 90acbb9

  • v2.0.0

    June 01, 2019

    💥 Breaking changes

    AVA now requires at least Node.js 8.9.4

    🚀 Per the Node.js release schedule, the 6.x releases reach end of live on April 30th. Consequently we've removed support in AVA. We are now testing with Node.js 12 though. 3a4afc6

    ✅ 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.

    ✅ 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:

    { "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 b1e54b1

    The CLI now only takes file paths, not glob patterns.

    ⚡️ We'd like some help updating our ESLint plugin 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

    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

    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

    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 avajs/flow-typed#1.

    Observable typing

    ⚡️ Test implementations may return observables. We've updated our TypeScript definition to require these to have a Symbol.observable function. c2d8218

    🆕 New features

    🔧 Configurable printing depth

    AVA now uses the util.inspect.defaultOptions.depth option when printing objects, so you can configure the depth. 98034fb

    Specify environment variables in your AVA config

    You can now specify environment variables in your config, using the environmentVariables object. a53ea15

    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! ebf4807
    • 👷 The dependency tracking in watch mode now respects custom require hooks you install in the worker processes. Thanks @lo1tuma! cb4c809
    • ✅ The TypeScript definition once again allows test.skip(macro) ba5cd80
    • 👕 AVA now exposes some methods to our ESLint plugin, allowing our plugin to support the new test & helper file selection. 51433be

    Focusing power-assert

    AVA comes with 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:

    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 has been updated to support this new assertion. Many thanks to @eemed for implementing this! 9406470

    Watch mode

    🖨 Watch mode now prints the available commands. Thanks @KompKK! cd256ac

    🐛 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! 23e302a
    • 👷 We're now shimming all TTY methods in the worker processes, thanks to @okyantoro. c1f6fdf

    📚 Documentation updates

    • ✅ We've added a note to say that, by default, AVA does not have a default test timeout. Thanks @amokmen! 99a10a1
