> 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

```bash
$ npm install karma-chrome-launcher --save-dev
```

## Configuration

```js
// karma.conf.js
module.exports = function(config) {
  config.set({
    browsers: ['Chrome', 'Chrome_without_security'], // You may use 'ChromeCanary' or 'Chromium' as well

    // you can define custom flags
    customLaunchers: {
      Chrome_without_security: {
        base: 'Chrome',
        flags: ['--disable-web-security']
      }
    }
  })
}
```

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).

```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
```
