generator-mocha-testem

Yeoman generator for Mocha+Testem

Mocha+Testem generator

Install:

npm install -g generator-mocha-testem
yo mocha-testem
testem

This assumes you're starting a new project.

  • mkdir myproject && cd myproject
  • yo webapp
  • Delete the test directory: rm -rf test
  • yo mocha-testem
  • Run testem. It should launch new Chrome and Firefox processes, which you can minimise. You can now use Testem for TDD in the usual way (see docs).
  • You can run grunt-server in another terminal at the same time.
  • In your spec runner (test/index.html), add script tags for your implementation code, which should look something like this: <script src="../app/scripts/foo.js"></script>. Script tags for spec files should look like this: <script src="specs/foo-test.js"></script>.

This lets you use Testem in CI mode during your build process. It launches browsers, runs your tests in them, and closes them afterwards.

  • Remove grunt-mocha: npm uninstall -D grunt-mocha
  • Add grunt-testem: npm install -D grunt-testem
  • In your Gruntfile...
    • remove the entire config entry for mocha, and remove the test target of connect
    • find grunt.registerTask('test'..., remove the connect:test subtask, and change 'mocha' to 'testem'
    • add this config entry:
        testem: {
            main: {
                src: [ 'testem.json' ],
                dest: 'tests.tap'
            }
        }

Edit the launch_in_ci list of browsers in your testem.json if necessary. Now try running grunt test.

More steps are probably needed to get this working with Coffeescript... Instructions will appear here when I've worked it out myself. PRs welcome.
