Example of how you can test your AngularJS providers.

What is this?

An example of how you can test your AngularJS providers.

Relevant files

  • sampleProvider.js - A very simple configurable provider.
  • sampleProvider_spec.js - Some tests for the provider that should give you an idea of how you might test your real provider

How to run

npm install
bower install
karma start karma.conf.js
