v0.25.0

Compare Source

Another small release while we're gearing up for a 1.0 built with Babel 7. This is likely to be the last 0. release, but we may go through a few beta releases for 1.0 whilst we wait for Babel 7 to get out of beta itself.

• We now detect @std/esm in AVA's "require" configuration and will use it to require subsequent modules 72c53be
• t.log() now supports multiple arguments 4f896c2
• AVA no longer globally modifies Error.stackTraceLimit in the worker processes f00f3c4
• We've improved TypeScript typings for t.snapshot(value, options) 29e5dfd
• Source maps for the test files can now be resolved if they reside on a different drive aaddc37
• Code excerpts shown for test failures now handle Windows-style linebreaks 947f207

v0.24.0

Compare Source

Highlights 💡

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

Miscellaneous 🕯

• Before and after hooks are no longer run when all tests are skipped 1cd3a04
• Improved output of assertion statements when tests fail 37e8b49
• Improved feedback when t.is() values are deeply equal but not the same c41b2af

Highlights 🕴

NODE_ENV=test ✨

AVA will now set process.env.NODE_ENV to 'test', as long as the NODE_ENV environment variable has not already been set. 42e7c74

Improved snapshot storage location 🗃

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 snapshotDir option in the package.json file. 7fadc34

Matching anonymous tests 🕵️

--match='*' now matches all tests, including those without a title. 1df502d

Miscellaneous 🎒

• The verbose logger now only displays the timestamp when in watch mode 1ea758f
• Anonymous functions are now included in stack traces c72f4f2
• Concurrency is now capped at 2 in CI environments 3f81fc4
• AVA no longer calls Bluebird.longStackTraces(). If you're using Bluebird you may want to call this yourself using a require script. ebf78b3 61101d9
• There's a new recipe for endpoint testing using Mongoose c9fe8db
• The browser testing recipe has been updated with an example of exposing global variables, such as jQuery f43d5ae
• t.log() is now supported in the Flow and TypeScript type definitions 64b7755
• t.title is now supported in the TypeScript type definitions 3c8b1be
• t.snapshot() now has a better Flow type definition ded7ab8

v0.22.0

Compare Source

There's but a few commits in this release, but we've made a big change to how AVA manages its test workers 👩🏼‍🔬👨🏼‍🏭👨🏿‍🚀👨🏻‍⚕️👩🏽‍💼.

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's package.json configuration, or by passing the --concurrency flag. We've also beefed up input validation on that flag. b6eef5a

Unfortunately this does change how test.only() behaves. AVA can no longer guarantee that normal tests won't run. For now, if you want to use test.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 the test.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 to stdout like console.log. 14f7095

Miscellaneous

• The WebStorm recipe has been updated with instructions on how to enable the Node.js inspector. d8c21a6
• The app setup in the endpoint testing recipe has been fixed e28be05
• The t.notThrows() example has been clarified 57f5007

v0.21.0

Compare Source

This is primarily a bug fix release, but some features did sneak in:

• Additional arguments can be passed when profiling 05bfafe
• Though not officially supported, AVA now works better with Wallaby.js’ diff view 3f6e134
• Expanded the Webstorm recipe to include setup instructions using npm 2b4e35d

This release includes the following patches:

• Fixes for t.deepEqual() and magic assert diffs 9e4ee3f
• Ensure AVA doesn’t use Buffer APIs that are unavailable in Node.js releases older than 4.5 d0fc8c9
• Changed Flow typing of the t.throws() promise return value to be any 4a769f8
• Update Flow typing of test() so macros are compatible with the latest flow-bin e794e73

v0.20.0

Compare Source

Today’s release is very exciting. After adding magic assert and snapshot testing we found that these features sometimes disagreed with each other. t.deepEqual() would return false, yet AVA wouldn’t show a diff. Snapshot tests cared about Set order but t.deepEqual() didn’t. @​novemberborn came to the realization that comparing and diffing object trees, and doing so over time with snapshots, are variations on the same problem. Thus he started ConcordanceJS, a new project that lets you compare, format, diff and serialize any JavaScript value. This AVA release reaps the fruits of his labor.

Highlights

More magical asserts

Magic assert will now always show the difference between actual and expected values. If an unexpected error occurs it’ll print all (enumerable) properties of the error which can make it easier to debug your program.

More details of an object are printed, like the constructor name and the string tag. Buffers are hex-encoded with line breaks so they’re easy to read:

t.deepEqual() improvements

t.deepEqual() and t.notDeepEqual() now use concordance, rather than lodash.isequal. This changes what values AVA considers to be equal, making the t.deepEqual() assertion more predictable. You can now trust that all aspects of your objects are compared.

Object wrappers are no longer equal. The following assertion will now fail:

t.deepEqual(Object(1), 1); // fails

For Map and Set objects to be equal, their elements must now be in the same order:

const actual = new Set(['hello', 'world']);
t.deepEqual(actual, new Set(['hello', 'world'])); // passes
t.deepEqual(actual, new Set(['world', 'hello']) // fails

With this release AVA will compare all enumerable properties of an object. For an array this means that the comparison considers not just the array elements. The following are no longer considered equal:

const actual = [1, 2, 3];
const expected = [1, 2, 3];
expected.also = 'a property';
t.deepEqual(actual, expected); // fails

The same goes for Map and Set objects, errors, and so forth:

const actual = new TypeError('Bad value');
const expected = new TypeError('Bad value');
expected.value = 41;
t.deepEqual(actual, expected); // fails

You used to be able to compare Arguments object to an object literal:

const args = (function() { return arguments; })('hello', 'world');
t.deepEqual(args, {0: 'hello', 1: 'world'}); // now fails

Instead you must now use:

const args = (function() { return arguments; })('hello', 'world');
t.deepEqual(args, ['hello', 'world']); // passes

(Of course you can still compare Arguments objects to each other.)

New in this release is the ability to compare React elements:

t.deepEqual(<HelloWorld/>, <HelloWorld/>);

const renderer = require('react-test-renderer');
t.deepEqual(renderer.create(<HelloWorld/>).toJSON(), <h1>Hello World</h1>);

Snapshot improvements

Snapshots too now use concordance. This means values are compared with the snapshot according to the same rules as t.deepEqual(), albeit with some minor differences:

• Argument objects can only be compared to Argument objects
• Functions are compared by name and other enumerable properties
• Promises are compared by their constructor and additional enumerable properties
• Symbols are compared by their string serialization. Registered and well-known symbols will never equal symbols with similar descriptions

Note that Node.js versions before 6.5 cannot infer names of all functions . AVA will pass a snapshot assertion if it determines the name information is unreliable.

AVA now saves two files when snapshotting. One, ending in the .snap extension, contains a compressed serialization of the expected value. The other is a readable Markdown file that contains the snapshot report. You should commit both to source control. The report file can be used to see what is in your snapshots and to compare snapshot changes over time.

Try it out with our snapshot example! Or check out an example snapshot report.

The snapshot file location now follows your test layout. If you use a test folder, they’ll be placed in test/snapshots. With __tests__ they’ll be placed in __tests__/__snapshots__. And if you just have a test.js in your project root the snapshot files will be written to test.js.snap and test.js.md. You may have to manually remove old snapshot files after installing this new AVA version. ebd572a

Improved snapshot support in watch mode

In watch mode, AVA now watches for changes to snapshot files. This is handy when you revert changes while the watcher is running. Snapshot files are correctly tracked as test dependencies, so the right tests are rerun. Typing u, followed by Enter updates the snapshots in the tests that just ran. (And the watcher won’t rerun tests when snapshots are updated.) 87eef84 dbc78dc f507e36 50b60a1

Node.js 8 support

AVA 0.19 already worked great with Node.js 8, and we’ve made it even better by removing unnecessary Babel transpilations in our stage-4 preset. We’re now also forwarding the --inspect-brk flag for debugging purposes. e456951 a868b02

New and improved recipes

We’ve added new recipes and improved others:

• Learn how to debug tests with Visual Studio Code 1d04153 140c0e0
• Test MongoDB integrations with per-test isolation 970872c
• Using AVA with Vue.js ff3bba9
• There’s several ways of using webpack to precompile tests and sources. We’ve broken down the pros and cons f228401
• We’ve added a note to the browser testing recipe, discouraging the use of browser-env c01ac05

Miscellaneous

• Specifying --concurrency without a value now causes AVA to exit with an error 8c35a1a
• Using t.throws() with a resolved promise now prints a helpful error message dfca2d9
• The t.title accessor has been documented. 549e99b
