  3. Install other optional browser launchers:

    2. npm install karma-safari-launcher
    3. npm install karma-ie-launcher
    4. Update the browsers: ['Chrome'] property in karma.conf.js to add additional browsers to test against.
  4. The source repository contains a karma.conf.js file: this is configures the Karma test runner
  5. (Optional) Install the IntelliJ Karma test runner:
  6. Preferences -> Plugins -> Search for Karma -> Install (at the time of writing there was only 1 matching plugin)
  7. Create a run configuration:
    1. Run -> Edit Configurations -> New -> Karma
    2. Give it a name
    3. Select the karma.conf.js file from the root of the project directory as the Configuration File
    4. The other default values are fine.

Writing Tests

The karma.conf.js file contains a list of all Javascript resources required for testing in the files list. If you create a new file, you must update the karma.conf.js file or your tests won't work.

// list of files / patterns to load in the browser
files: [

The order is important!

Jasmine tests live in the tests/js/specs/ directory. Update existing files or add new ones as necessary.

Code Coverage

You can see a code coverage report for the javascript files by following these steps:

  1. Command Line
    1. Run karma start
    2. Open coverage/<browser>/index.html
  2. IntelliJ
    1. Run the karma configuration using the Run 'karma' with Coverage option (the 3rd toolbar button after the run dropdown).
    2. Open coverage/<browser>/index.html
    3. IntelliJ will also annotate the filenames in the project explorer with a percentage of lines covered.
