A Karma plugin - adapter for Dart unittest testing framework.


Adapter for the Dart unittest testing framework.

For more information on Karma-runner see the homepage.

You'll need node.js: http://nodejs.org/download/

Install karma and karma-dart adapter npms:

$ npm install karma-dart

Refer to npm install documentation for more details and install options.

and you'll need the following dependencies in your pubspec.yaml

unittest: any
browser: any

The following is an example of karma config.

module.exports = function(config) {
    basePath: '.',
    frameworks: ['dart-unittest'],
    // list of files / patterns to load in the browser 
    // all tests must be 'included', but all other libraries must be 'served' and 
    // optionally 'watched' only. 
    files: [
      {pattern: '**/*.dart', watched: true, included: false, served: true},
    autoWatch: true,
    // If browser does not capture in given timeout [ms], kill it 
    captureTimeout: 5000,
    plugins: [

You can run karma from the local folder:

$ node node_modules/karma/bin/karma start karma-dart.conf

or if you installed it with -g flag just

$ karma start karma-dart.conf

Then just open http://localhost:9876/ in Dartium.

  • Missing Dartium launcher.
  • Each test file must be a library -- due to the nature of the test runner, this is required.
