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! 4f093ab

TAP improvements

@tymfear has been on a roll improving our TAP reporter. t.log() output is now compliant with the spec 99ab93a. Tests that did not run due to timeouts are now reported 98595da.

Next-generation configuration

AVA 4 will add full support for ESM configuration files as well as allowing you to have asynchronous factory functions a2f2614. 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:

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" 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 avajs/ava@v3.14.0...v3.15.0 for all changes.

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! e66b54c

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.

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 feature. Read more in our documentation. Thank you @macarie for working on this! 5c9dbb9

Comparison bugfix

There was a bug in our comparison library 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.

New `t.like()` assertion

Thanks to @futpib we now have a t.like() assertion 19c4f35:

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.

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.

This assertion was previously introduced as an experiment.

VSCode 1.47 debugging improvements

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 for putting this together. f72fab4

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 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

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 it now fails properly instead of crashing. d01db61

`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 d01db61.

Fixed TypeScript definition for `t.like()`

The experimental t.like() assertion should now work better with TypeScript.

New experiments!

Thanks to @futpib we now have an experimental t.like() assertion 19c4f35:

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.

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 and let us know what you think.

@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. This will be the behavior in AVA 4.

To enable both these experiments update your AVA configuration:

package.json:

{
	"ava": {
		"nonSemVerExperiments": {
			"likeAssertion": true,
			"reverseTeardowns": true
		}
	}
}

ava.config.js:

export default {
	nonSemVerExperiments: {
		likeAssertion: true,
		reverseTeardowns: true
	}
}

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! 2e7c76b

Run tests at specific line numbers

AVA can now run tests at specific line numbers! 🎉

Given the following test file:

test.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.

Thank you @ulken for your hard work and patience to get this shipped. 1222ce9

Test-specific teardown functions

Sometimes tests have side-effects you want to clean up. @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

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, 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

Watch mode with the default reporter

Watch mode with the default reporter once again accepts key input. Thanks @pcdevil! 59c227d

ICYMI

afterEach() and afterEach.always() hooks can now determine whether the test passed. Thank you @bunysae for contributing this! 8f312c0

		// Do something because the test passed
	} else {

Introducing the `t.try()` assertion

The new t.try() allows you to try assertions without causing the test to fail:

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. 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.

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.

Once again, thank you @qlonik for contributing this new assertion.

In case you missed it: ESM support

As of the 3.3.0 release, AVA can load ESM test files! Check our updated ES Modules recipe for details.

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. d0e2161 @stavalfi

This release improves the integration with the new [@ava/typescript][@ava/typescript] package, which allows AVA to load pre-compiled TypeScript files.

First, install the new [@ava/typescript][@ava/typescript] package:

npm install --save-dev @&#8203;ava/typescript@^1.1

Now let's assume your TypeScript files are in a src directory, output to a build directory. Configure AVA like so:

ava.config.js file:

export default {
  typescript: {
    rewritePaths: {
      'src/': 'build/'
    }
  }
}

Compile your TypeScript files and run your tests! Or, to run a specific test file, run npx ava src/test.ts.

For more examples see the [@ava/typescript][@ava/typescript] package.

As exciting as this is, it's still early days. We need your help improving our TypeScript support. Check out the open issues.

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 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.

Without Babel you'll have to resort to using require() functions in your JavaScript files. But, you say, Node.js 13 supports ECMAScript Modules!

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:

npx ava debug test.js

Connect to the debugger with Chrome DevTools. Or set up a debugger in VSCode.

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 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 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.

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 .

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:

 export default {
-  sources: ['!examples/**/*']
+  ignoredByWatcher: ['examples/**/*']
 }

CLI changes

Internally we've replaced meow by 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:

npx ava reset-cache

File selection (again!)

AVA again accepts glob patterns via the CLI:

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:

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 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.
We've added a Selenium WebDriver JS recipe.

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: https://github.com/avajs/ava/issues/2250

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 https://github.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

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

Bug fixes

We've fixed a rather embarrasing bug with t.throws() and t.throwsAsync(). 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 for both spotting and fixing this. 82daa5e
1.2.0 contained a regression which meant that if you faked clearTimeout(), you'd break AVA. That's now been fixed. 40f331c
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

New features

You can now use require() in ava.config.js files to load non-ES modules. 334e15b

New features

You can now set a timeout for test themselves. The test will fail if this timeout is exceeded. The timeout is reset each time an assertion is made:

test('foo', t => {
	t.timeout(100); // 100 milliseconds
	// Write your assertions here
});

AVA also has a global timeout feature. 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
