Raw Blame History

8.2.0 / 2020-10-15

The major feature added in v8.2.0 is addition of support for global fixtures.

While Mocha has always had the ability to run setup and teardown via a hook (e.g., a before() at the top level of a test file) when running tests in serial, Mocha v8.0.0 added support for parallel runs. Parallel runs are incompatible with this strategy; e.g., a top-level before() would only run for the file in which it was defined.

With global fixtures, Mocha can now perform user-defined setup and teardown regardless of mode, and these fixtures are guaranteed to run once and only once. This holds for parallel mode, serial mode, and even "watch" mode (the teardown will run once you hit Ctrl-C, just before Mocha finally exits). Tasks such as starting and stopping servers are well-suited to global fixtures, but not sharing resources--global fixtures do not share context with your test files (but they do share context with each other).

Here's a short example of usage:

// fixtures.js

// can be async or not
exports.mochaGlobalSetup = async function() {
  this.server = await startSomeServer({port: process.env.TEST_PORT});
  console.log(`server running on port ${this.server.port}`);
};

exports.mochaGlobalTeardown = async function() {
  // the context (`this`) is shared, but not with the test files
  await this.server.stop();
  console.log(`server on port ${this.server.port} stopped`);
};

// this file can contain root hook plugins as well!
// exports.mochaHooks = { ... }

Fixtures are loaded with --require, e.g., mocha --require fixtures.js.

For detailed information, please see the documentation and this handy-dandy flowchart to help understand the differences between hooks, root hook plugins, and global fixtures (and when you should use each).

🎉 Enhancements

For implementors of custom reporters:

  • #4409: Parallel mode and custom reporter improvements (@boneskull):
    • Support custom worker-process-only reporters (Runner.prototype.workerReporter()); reporters should subclass ParallelBufferedReporter in mocha/lib/nodejs/reporters/parallel-buffered
    • Allow opt-in of object reference matching for "sufficiently advanced" custom reporters (Runner.prototype.linkPartialObjects()); use if strict object equality is needed when consuming Runner event data
    • Enable detection of parallel mode (Runner.prototype.isParallelMode())

🐛 Fixes

  • #4476: Workaround for profoundly bizarre issue affecting npm v6.x causing some of Mocha's deps to be installed when mocha is present in a package's devDependencies and npm install --production is run the package's working copy (@boneskull)
  • #4465: Worker processes guaranteed (as opposed to "very likely") to exit before Mocha does; fixes a problem when using nyc with Mocha in parallel mode (@boneskull)
  • #4419: Restore lookupFiles() in mocha/lib/utils, which was broken/missing in Mocha v8.1.0; it now prints a deprecation warning (use const {lookupFiles} = require('mocha/lib/cli') instead) (@boneskull)

Thanks to @AviVahl, @donghoon-song, @ValeriaVG, @znarf, @sujin-park, and @majecty for other helpful contributions!

8.1.3 / 2020-08-28

🐛 Fixes

  • #4425: Restore Mocha.utils.lookupFiles() and Webpack compatibility (both broken since v8.1.0); Mocha.utils.lookupFiles() is now deprecated and will be removed in the next major revision of Mocha; use require('mocha/lib/cli').lookupFiles instead (@boneskull)

8.1.1 / 2020-08-04

  • #4394: Fix regression wherein certain reporters did not correctly detect terminal width (@boneskull)

8.1.0 / 2020-07-30

In this release, Mocha now builds its browser bundle with Rollup and Babel, which will provide the project's codebase more flexibility and consistency.

While we've been diligent about backwards compatibility, it's possible consumers of the browser bundle will encounter differences (other than an increase in the bundle size). If you do encounter an issue with the build, please report it here.

This release does not drop support for IE11.

💥 Breaking Changes

  • #3149: Drop Node.js v4.x support (@outsideris)
  • #3556: Changes to command-line options (@boneskull):
    • --grep and --fgrep are now mutually exclusive; attempting to use both will cause Mocha to fail instead of simply ignoring --grep

  • #3125: For consumers of Mocha's programmatic API, all exceptions thrown from Mocha now have a code property (and some will have additional metadata). Some Error messages have changed. Please use the code property to check Error types instead of the message property; these descriptions will be localized in the future. (@craigtaub)

📠 Deprecations

These are soft-deprecated, and will emit a warning upon use. Support will be removed in (likely) the next major version of Mocha:

  • -gc users should use --gc-global instead
  • Consumers of the function exported by bin/options should now use the loadMochaOpts or loadOptions (preferred) functions exported by the lib/cli/options module

Regarding the Mocha class constructor (from lib/mocha):

  • Use property color: false instead of useColors: false
  • Use property timeout: false instead of enableTimeouts: false

All of the above deprecations were introduced by #3556.

mocha.opts is now considered "legacy"; please prefer RC file or package.json over mocha.opts.

🎉 Enhancements

Enhancements introduced in #3556:

  • Mocha now supports "RC" files in JS, JSON, YAML, or package.json-based (using mocha property) format

    • .mocharc.js, .mocharc.json, .mocharc.yaml or .mocharc.yml are valid "rc" file names and will be automatically loaded
    • Use --config /path/to/rc/file to specify an explicit path
    • Use --package /path/to/package.json to specify an explicit package.json to read the mocha prop from
    • Use --no-config or --no-package to completely disable loading of configuration via RC file and package.json, respectively
    • Configurations are merged as applicable using the priority list:
      1. Command-line arguments
      2. RC file
      3. package.json
      4. mocha.opts
      5. Mocha's own defaults
    • Check out these example config files

  • Node/V8 flag support in mocha executable:

    • Support all allowed node flags as supported by the running version of node (also thanks to @demurgos)
    • Support any V8 flag by prepending --v8- to the flag name
    • All flags are also supported via config files, package.json properties, or mocha.opts
    • Debug-related flags (e.g., --inspect) now imply --no-timeouts
    • Use of e.g., --debug will automatically invoke --inspect if supported by running version of node

  • Support negation of any Mocha-specific command-line flag by prepending --no- to the flag name

  • Interfaces now have descriptions when listed using --interfaces flag

  • Mocha constructor supports all options

  • --extension is now an alias for --watch-extensions and affects non-watch-mode test runs as well. For example, to run only test/*.coffee (not test/*.js), you can do mocha --require coffee-script/register --extensions coffee.

  • #3552: tap reporter is now TAP13-capable (@plroebuck & @mollstam)

  • #3535: Mocha's version can now be queried programmatically via public property Mocha.prototype.version (@plroebuck)

  • #3428: xunit reporter shows diffs (@mlucool)

  • #2529: Runner now emits a retry event when tests are retried (reporters can listen for this) (@catdad)

5.0.2 / 2018-03-05

This release fixes a class of tests which report as false positives. Certain tests will now break, though they would have previously been reported as passing. Details below. Sorry for the inconvenience!

🐛 Fixes

  • #3226: Do not swallow errors that are thrown asynchronously from passing tests (@boneskull). Example:

    ```js it('should actually fail, sorry!', function (done) { // passing assertion assert(true === true);

    // test complete & is marked as passing done();

    // ...but something evil lurks within setTimeout(() => { throw new Error('chaos!'); }, 100); }); ```

    Previously to this version, Mocha would have silently swallowed the chaos! exception, and you wouldn't know. Well, now you know. Mocha cannot recover from this gracefully, so it will exit with a nonzero code.

    Maintainers of external reporters: If a test of this class is encountered, the Runner instance will emit the end event twice; you may need to change your reporter to use runner.once('end') intead of runner.on('end').
