Fixed stuff.
#### :bug: Fixes
- [#4489](https://togithub.com/mochajs/mocha/issues/4489): Fix problematic handling of otherwise-unhandled `Promise` rejections and erroneous "`done()` called twice" errors ([**@boneskull**](https://togithub.com/boneskull))

### [`v8.2.0`](https://togithub.com/mochajs/mocha/blob/master/CHANGELOG.md#820--2020-10-16)
[Compare Source](https://togithub.com/mochajs/mocha/compare/v8.1.3...v8.2.0)
The major feature added in v8.2.0 is addition of support for [_global fixtures_](https://mochajs.org/#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](https://mochajs.org/#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:
```js
// 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](https://mochajs.org/#global-fixtures) and this handy-dandy [flowchart](https://mochajs.org/#test-fixture-decision-tree-wizard-thing) to help understand the differences between hooks, root hook plugins, and global fixtures (and when you should use each).
#### :tada: Enhancements
- [#4308](https://togithub.com/mochajs/mocha/issues/4308): Support run-once [global setup & teardown fixtures](https://mochajs.org/#global-fixtures) ([**@boneskull**](https://togithub.com/boneskull))
- [#4442](https://togithub.com/mochajs/mocha/issues/4442): Multi-part extensions (e.g., `test.js`) now usable with `--extension` option ([**@jordanstephens**](https://togithub.com/jordanstephens))
- [#4472](https://togithub.com/mochajs/mocha/issues/4472): Leading dots (e.g., `.js`, `.test.js`) now usable with `--extension` option ([**@boneskull**](https://togithub.com/boneskull))
- [#4434](https://togithub.com/mochajs/mocha/issues/4434): Output of `json` reporter now contains `speed` ("fast"/"medium"/"slow") property ([**@wwhurin**](https://togithub.com/wwhurin))
- [#4464](https://togithub.com/mochajs/mocha/issues/4464): Errors thrown by serializer in parallel mode now have error codes ([**@evaline-ju**](https://togithub.com/evaline-ju))
_For implementors of custom reporters:_
- [#4409](https://togithub.com/mochajs/mocha/issues/4409): Parallel mode and custom reporter improvements ([**@boneskull**](https://togithub.com/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()`)
#### :bug: Fixes
- [#4476](https://togithub.com/mochajs/mocha/issues/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**](https://togithub.com/boneskull))
- [#4465](https://togithub.com/mochajs/mocha/issues/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**](https://togithub.com/boneskull))
- [#4419](https://togithub.com/mochajs/mocha/issues/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**](https://togithub.com/boneskull))
