Heads Up! You're viewing the docs for v0.8, an old version of Karma. v0.12 is the newest.

Configuration

In order to serve you well, Karma needs to know about your project. That's done through a configuration file.

For an example file, see test/client/karma.conf.js which contains most of the options.

Generating the config file

You can write the config file by hand or copy paste it from another project.

A third way is to use karma init to generate it.

# This will ask you a few questions and generate a new config file
# called my.conf.js
$ karma init my.conf.js

Starting Karma

When starting Karma, you can pass a path to the configuration file as an argument.

By default, Karma will look for karma.conf.js in the current directory.

# Start Karma using your configuration
$ karma start my.conf.js

For more info about configuration file, see the configuration file docs.

Command line arguments

Some of the configurations can be specified as a command line argument, which overrides the configuration from the config file.

Try karma start --help if you want to see all available options.
