karma-chrome-launcher
Launcher for Google Chrome, Google Chrome Canary and Google Chromium.
Installation
The easiest way is to keep karma-chrome-launcher
as a devDependency in your package.json
,
by running
$ npm i -D karma-chrome-launcher
Configuration
// karma.conf.jsmodule { config}
The --user-data-dir
is set to a temporary directory but can be overridden on a custom launcher as shown below.
One reason to do this is to have a permanent Chrome user data directory inside the project directory to be able to
install plugins there (e.g. JetBrains IDE Support plugin).
customLaunchers: Chrome_with_debugging: base: 'Chrome' chromeDataDir: path
You can pass list of browsers as a CLI argument too:
$ karma start --browsers Chrome,Chrome_without_security
