Files

The files array determines which files are included in the browser and which files are watched and served by Karma.

Pattern matching and basePath #

• All of 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 minimatch 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 #

Each pattern is either a simple string or an object with four properties:

pattern #

• Description. The pattern to use for matching. This property is mandatory.

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?

Preprocessor tranformations #

Depending on preprocessor configuration, be aware that files loaded may be transformed and no longer available in their native format. For instance, if html2js preprocessor is enabled, the actual .html files are no longer served - but rather available as window.__html__['my.html']. Read more about preprocessors.

Complete example #

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

files: [

  // simple patterns to load the needed testfiles
  // equals to {pattern: 'test/unit/*.spec.js', watched: true, served: true, included: true}
  'test/unit/*.spec.js',

  // this file gets served but will be ignored by the watcher
  // note if html2js preprocessor is active, reference as `window.__html__['compiled/index.html']`
  {pattern: 'compiled/index.html', watched: false},

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