See the Karma documentation for more info.
Karma runs the tests in the browser, but reports them in the CLI. This greatly improves your workflow by giving you constant, accurate feedback on the status of your tests.
PhantomJS is a great option too, but it has the one drawback that it won't expose browser inconsistencies.
I needed Karma configuration that plays nicely with RequireJS, that I could spin up automatically after running another RequireJS-based generator. This is designed to address that problem.
Install it globally
npm install -g generator-karma-require.
yo karma will generate a config file for your project:
karma.conf.js. It will then install the npm dependencies.
By default, running
yo karma will generate a pretty boring (and almost useless) config file. The real power is using the options to specify almost every part of the config file.
Note that you'll need to update your
Gruntfile.js if you don't specify the
There are a lot of options going on here. None of them are required and most are probably only useful when used with other generators calling this one.
