#4038: Add Node.js native ESM support (@giltayar)
Mocha supports writing your test files as ES modules:
- Node.js only v12.11.0 and above
- Node.js below v13.2.0, you must set
--experimental-modules option
- current limitations: please check our documentation
- for programmatic usage: see API: loadFilesAsync()
Note: Node.JS native ECMAScript Modules implementation has status: Stability: 1 - Experimental

: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)

tap reporter emits error messages (@chrmod)

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.jsonmocha.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)

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').
