v6.0.0

6.0.0 / 2019-02-18

💥 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)

📠 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

• #3726: Add ability to unload files from require cache (@plroebuck)

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)
