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). ```js customLaunchers: { Chrome_with_debugging: { base: 'Chrome', chromeDataDir: path.resolve(__dirname, '.chrome') } } ``` You can pass list of browsers as a CLI argument too: ```bash $ karma start --browsers Chrome,Chrome_without_security ``` ### Available browsers - Chrome - ChromeCanary - Chromium - ChromeHeadless (only on Chrome >= 59) - ChromeCanaryHeadless (only on Chrome >= 59) - Dartium ---- For more information on Karma see the [homepage].
