8.2.0 / 2020-10-16
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).

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.

📠 Deprecations
These are soft-deprecated, and will emit a warning upon use. Support will be removed in (likely) the next major version of Mocha:
-gcusers should use--gc-globalinstead- Consumers of the function exported by
bin/optionsshould now use theloadMochaOptsorloadOptions(preferred) functions exported by thelib/cli/optionsmodule
Regarding the Mocha class constructor (from lib/mocha):
- Use property
color: falseinstead ofuseColors: false - Use property
timeout: falseinstead ofenableTimeouts: 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 (usingmochaproperty) format.mocharc.js,.mocharc.json,.mocharc.yamlor.mocharc.ymlare valid "rc" file names and will be automatically loaded- Use
--config /path/to/rc/fileto specify an explicit path - Use
--package /path/to/package.jsonto specify an explicitpackage.jsonto read themochaprop from - Use
--no-configor--no-packageto completely disable loading of configuration via RC file andpackage.json, respectively - Configurations are merged as applicable using the priority list:
- Command-line arguments
- RC file
package.jsonmocha.opts- Mocha's own defaults
- Check out these example config files
-
Node/V8 flag support in
mochaexecutable:- Support all allowed
nodeflags as supported by the running version ofnode(also thanks to @demurgos) - Support any V8 flag by prepending
--v8-to the flag name - All flags are also supported via config files,
package.jsonproperties, ormocha.opts - Debug-related flags (e.g.,
--inspect) now imply--no-timeouts - Use of e.g.,
--debugwill automatically invoke--inspectif supported by running version ofnode
- Support all allowed
-
Support negation of any Mocha-specific command-line flag by prepending
--no-to the flag name -
Interfaces now have descriptions when listed using
--interfacesflag -
Mochaconstructor supports all options -
--extensionis now an alias for--watch-extensionsand affects non-watch-mode test runs as well. For example, to run onlytest/*.coffee(nottest/*.js), you can domocha --require coffee-script/register --extensions coffee. -

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
Runnerinstance will emit theendevent twice; you may need to change your reporter to userunner.once('end')intead ofrunner.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!
💥 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.
