Heads Up! You're viewing the docs for v0.8, an old version of Karma. v6.4 is the newest.

Files

The files array determines which files are loaded, watched and served by Karma.

Adapters #

The first thing you usually need is an adapter. The following adapters are bundled with Karma:

  • Jasmine (JASMINE, JASMINE_ADAPTER)
  • Mocha (MOCHA, MOCHA_ADAPTER)
  • QUnit (QUNIT, QUNIT_ADAPTER)
  • RequireJS (REQUIRE, REQUIRE_ADAPTER)
  • Angular Scenario Runner (ANGULAR_SCENARIO, ANGULAR_SCENARIO_ADAPTER)

If you want to use any of these, add <FRAMEWORK> and <FRAMEWORK>_ADAPTER to your files list. So for example if you want to use Mocha you have the following in your config file:

files = [
  MOCHA,
  MOCHA_ADAPTER
];

Pattern matching and basePath #

  • All the relative patterns will get resolved to basePath first.
  • If the basePath is a relative path, it gets resolved to the directory where the configuration file is.
  • Eventually, all the patterns will get resolved into files using glob, so you can use expressions like test/unit/**/*.spec.js.

Ordering #

  • The order of patterns determines the order of files in which they are included in the browser.
  • Multiple files matching a single pattern are sorted alphabetically.
  • Each file is included exactly once. If multiple patterns match the same file, it's included as if it only matched the first pattern.

Included, served, watched #

Since version 0.5.2 there is the ability to configure the patterns more closely.

If you define them like before a simple pattern like 'test/unit/*.js' this gets expanded internally to the following:

  {pattern: 'test/unit/*.js', watched: true, included: true, served: true}

pattern #

  • Description. The pattern to use for matching.

watched #

  • Type. Boolean
  • Default. true
  • Description. If autoWatch is true all files that have set watched to true will be watched for changes.

included #

  • Type. Boolean
  • Default. true
  • Description. Should the files be included in the browser using <script> tag? Use false if you wanna load them manually, eg. using Require.js.

served #

  • Type. Boolean
  • Default. true
  • Description. Should the files be served by Karma's webserver?

Complete example #

Here is a complete example showing the different options that are possible.

files = [

  // Adapter
  MOCHA,
  MOCHA_ADAPTER,

  // simple patterns to load the needed testfiles
  'test/fixtures/**/*.html',
  'test/unit/*.spec.js',

  // this file gets served but will be ignored by the watcher
  {pattern: 'compiled/index.html', watched: false},

  // this file only gets watched but otherwise ignored
  {pattern: 'app/index.html', included: false, served: false}
];
