Mocha needs YOU!

Did you know Mocha is a dependency of over 100,000 projects published to npm alone?

Despite this, we're currently unable to merge most pull requests due to lack of maintenance resources.

Are you interested in triaging issues or reviewing open PRs? Have some time to hack on its codebase? If you would like to help maintain Mocha, please contact @boneskull on Gitter.

Thank you 😘 to all of you interested in helping. These are Mocha's immediate needs:

  1. Increase test coverage on Node.js and browser
  • Increase integration coverage for all reporters
    • html reporter must be tested in browser
    • Basic console reporters (not nyan, landing, etc.) must be tested in both browser and Node.js contexts; PhantomJS can consume all console reporters
    • Filesystem-based reporters must be tested in Node.js context
  • Increase coverage against all interfaces (exports in particular). Ideally this becomes a "matrix" where we repeat sets of integration tests across all interfaces.
  • Refactor non-Node.js-specific tests to allow them to run in a browser context. Node.js-specific tests include those which require the CLI or filesystem. Most everything else is fair game.
  1. Review current open pull requests
  • We need individuals familiar with Mocha's codebase. Got questions? Ask them in our chat room.
  • Pull requests must have supporting tests. The only exceptions are pure cosmetic or non-functional changes.
  • Pull request contributors must sign the CLA.
  1. Close old, inactive issues and pull requests
  • A bot should do this. We need a bot. Got a bot?
  1. Triage issues
  • If we run into "critical" bugs, they need fixing.
  • "Critical" means Mocha is broken w/o workarounds for a large percentage of users
  • Otherwise: respond to issues, close new dupe issues, confirm bugs, ask for more info, etc.

Once we gain ground on the above items, we can work together formalize our contribution guidelines and governance. For further info & ideas, please see our projects.

You needn't be a maintainer to submit a pull request for test coverage!
