node package manager





A thin wrapper around mocha that finds tests anywhere in your project and provides a utility that gets tests up and running quickly

Supported on Node.js versions 4 and 6

  • npm install --save-dev mycha
  • add ./node_modules/.bin to your PATH environment variable
  • mycha install

    • prompts you for where you would like to install your default test helper, testHelperPath

      • If testHelperPath has an extension found here then it writes the test helper in that language and updates the configuration file accordingly
    • runs

      npm install --save-dev chai sinon sinon-chai
    • writes to testHelperPath

      process.env.NODE_ENV = 'test';
      var chai = require('chai');
      var sinon = require('sinon');
      global.chai = chai;
      global.expect = chai.expect;
      global.sinon = sinon;
    • writes to mycha.yml

      # Environment variables to add to process.env when running mocha
      mochaEnv: {}
      # Default options to pass to mocha (can be overridden by command line options)
        colors: true
        reporter: dot
      # Path patten used for finding tests (see
      testFilePattern: '**/*{spec,test}.js'
      # Files to include before all tests
        - #{testHelperPath}
  • mycha [mochaOptions] [<folder>...] [<file>...]

    • if no folders or files are specified runs all tests
    • if folders or files are specified, pass them through to mocha

To add a new compiler, add an entry here and add a language specific version of the test helper here.
