How can I automate both E2E and unit tests with Yeoman & AngularJS?

Question

I\'m using Yeoman and generator-angular to manage AngularJS apps, but I\'m having trouble with automated testing.

Running grunt test will run unit tests onc

Answer 1

Within the karma.conf.js file (approx line:38) find autoWatch = false; and change it to true.

Now if you run grunt karma:unit you will find that it leaves the test server running and any changes to project files immediately run the tests again.

Answer 2

You can try this to run only e2e tests

grunt karma:e2e

Answer 3

As I mentioned in a comment to your question - PhantomJS saves a lot of hassle. That aside, I believe you can handle everything from within your Gruntfile and just continue to run grunt test to start the whole thing.

grunt-karma allows full customization of your karma options with some handy add-ons.

From the docs:

....

You can override any of the config file's settings directly:

karma: {   
  unit: {
    configFile: 'karma.conf.js',
    runnerPort: 9999,
    singleRun: true,
    browsers: ['PhantomJS']   
  }
}

Sharing Configs

If you have multiple targets, it may be helpful to share common configuration settings between them. Grunt-karma supports this by using the options property:

karma: {
  options: {
    configFile: 'karma.conf.js',
    runnerPort: 9999,
    browsers: ['Chrome', 'Firefox']
  },
  continuous: {
    singleRun: true
    browsers: ['PhantomJS']
  },
  dev: {
    reporters: 'dots'
  }
}

Additionally you may want to snoop around in Yeoman's generator-angular Gruntfile code to see what else may be available or at least mockable.
