:bug: Fixes

  • Fix missing mocharc.json in published package (@boneskull)

6.0.0-0 / 2019-01-01

Documentation for this release can be found at next.mochajs.org!

Welcome @plroebuck, @craigtaub, & @markowsiak to the team!

:boom: 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
    • --compilers is no longer supported; attempting to use will cause Mocha to fail with a link to more information
    • -d is no longer an alias for --debug; -d is currently ignored
    • #3275: --watch-extensions no longer implies js; it must be explicitly added (@TheDancingCode)
  • #2908: tap reporter emits error messages (@chrmod)
  • #2819: When conditionally skipping in a before hook, subsequent before hooks and tests in nested suites are now skipped (@bannmoore)
  • #627: Emit filepath in "timeout exceeded" exceptions where applicable (@boneskull)
  • #3556: lib/template.html has moved to lib/browser/template.html (@boneskull)
  • #2576: An exception is now thrown if Mocha fails to parse or find a mocha.opts at a user-specified path (@plroebuck)
  • #3458: Instantiating a Base-extending reporter without a Runner parameter will throw an exception (@craigtaub)
  • #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)

:fax: 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.

:tada: 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:
    • Command-line arguments
    • RC file
    • package.json
    • mocha.opts
    • 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)

  • #2962, #3111: In-browser notification support; warn about missing prereqs when --growl supplied (@plroebuck)

:bug: Fixes

  • #3265: Fixes regression in "watch" functionality introduced in v5.0.2 (@outsideris)

5.0.3 / 2018-03-06

This patch features a fix to address a potential "low severity" ReDoS vulnerability in the diff package (a dependency of Mocha).

:lock: Security Fixes

:nut_and_bolt: Other

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!

:bug: 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').

5.0.0 / 2018-01-17

Mocha starts off 2018 right by again dropping support for unmaintained rubbish.

Welcome @vkarpov15 to the team!

:boom: Breaking Changes

  • #3148: Drop support for IE9 and IE10 (@Bamieh) Practically speaking, only code which consumes (through bundling or otherwise) the userland buffer module should be affected. However, Mocha will no longer test against these browsers, nor apply fixes for them.

:bug: Bug Fix

3.0.1 / 2016-08-03

:bug: Bug Fix

3.0.0 / 2016-07-31

:boom: Breaking Changes

  • :warning: Due to the increasing difficulty of applying security patches made within its dependency tree, as well as looming incompatibilities with Node.js v7.0, Mocha no longer supports Node.js v0.8.
  • :warning: Mocha may no longer be installed by versions of npm less than 1.4.0. Previously, this requirement only affected Mocha's development dependencies. In short, this allows Mocha to depend on packages which have dependencies fixed to major versions (^).
  • .only() is no longer "fuzzy", can be used multiple times, and generally just works like you think it should. :joy:
  • To avoid common bugs, when a test injects a callback function (suggesting asynchronous execution), calls it, and returns a Promise, Mocha will now throw an exception:

```js const assert = require('assert');

it('should complete this test', function (done) {

return new Promise(function (resolve) {
  assert.ok(true);
  resolve();
})
  .then(done);

}); ```

The above test will fail with Error: Resolution method is overspecified. Specify a callback *or* return a Promise; not both..

  • When a test timeout value greater than 2147483648 is specified in any context (--timeout, mocha.setup(), per-suite, per-test, etc.), the timeout will be disabled and the test(s) will be allowed to run indefinitely. This is equivalent to specifying a timeout value of 0. See MDN for reasoning.
  • The dot reporter now uses more visually distinctive characters when indicating "pending" and "failed" tests.
  • Mocha no longer supports component.
  • The long-forsaken HTMLCov and JSONCov reporters--and any relationship to the "node-jscoverage" project--have been removed.
  • spec reporter now omits leading carriage returns (\r) in non-TTY environment.

:tada: Enhancements

  • #808: Allow regular-expression-like strings in --grep and browser's grep querystring; enables flags such as i for case-insensitive matches and u for unicode. (@a8m)
  • #2000: Use distinctive characters in dot reporter; , will denote a "pending" test and ! will denote a "failing" test. (@elliottcable)
  • #1632: Throw a useful exception when a suite or test lacks a title. (@a8m)
  • #1481: Better .only() behavior. (@a8m)
  • #2334: Allow this.skip() in async tests and hooks. (@boneskull)
  • #1320: Throw a useful exception when test resolution method is overspecified. (@jugglinmike)
  • #2364: Support --preserve-symlinks. (@rosswarren)

:bug: Bug Fixes

  • #2259: Restore ES3 compatibility. Specifically, support an environment lacking Date.prototype.toISOString(), JSON, or has a non-standard implementation of JSON. (@ndhoule, @boneskull)
  • #2286: Fix after() failing to execute if test skipped using this.skip() in beforeEach(); no longer marks the entire suite as "pending". (@dasilvacontin, @boneskull)
  • #2208: Fix function name display in markdown and html (browser) reporters. (@ScottFreeCode)
  • #2299: Fix progress bar in html (browser) reporter. (@AviVahl)

  • #2310: Ensure custom reporter with an absolute path works in Windows. (@silentcloud)
  • #2311: Fix problem wherein calling this.slow() without a value would blast any previously set value. (@boneskull)
  • #1813: Ensure Mocha's own test suite will run in Windows. (@tswaters, @TimothyGu, @boneskull)
  • #2317: Ensure all interfaces are displayed in --help on CLI. (@ScottFreeCode)
  • #1644: Don't exhibit undefined behavior when calling this.timeout() with very large values (@callumacrae, @boneskull)
  • #2361: Don't truncate name of thrown anonymous exception. (@boneskull)

2.5.3 / 2016-05-25

2.5.2 / 2016-05-24

2.5.1 / 2016-05-23

Thanks @entertainyou, @SimenB, @just-paja for the heads-up.

2.5.0 / 2016-05-23

This has been awhile coming! We needed to feel confident that the next release wouldn't break browser compatibility (e.g. the last few patch releases).

Browser Tests in CI

We now run unit tests against PhantomJS v1.x and an assortment of browsers on SauceLabs, including:

  • Internet Explorer v8.0
  • Chrome (latest)
  • Firefox (latest)
  • Safari (latest)
  • Microsoft Edge (latest)

To accomplish this, we now run Mocha's unit tests (and a handful of integration tests) via Karma and a modified karma-mocha. Along the way, we had to solve issue #880 (apologies to @mderijcke and @sukima who had PRs addressing this), as well as replace most usages of should with expect.js for IE8.

Going forward, when sending PRs, your code will only run against PhantomJS v1.x (and not hit SauceLabs) because security.

Node.js 6.x

Node.js 6.x "just worked" before, but now it's in the CI matrix, so it's "officially" supported. Mocha still retains support for Node.js 0.8.x.

"Minor" Release

You'll see mostly bug fixes below, but also a couple features--as such, it's a "minor" release.

TYVM
