A command line interface to run browser tests over BrowserStack.

Usage

Install globally:

npm -g install browserstack-runner

Then, after setting up the configuration, run tests with:

browserstack-runner

You can also install locally and run the local binary:

npm install browserstack-runner
node_modules/.bin/browserstack-runner

Configuration

To run browser tests on BrowserStack infrastructure, you need to create a browserstack.json file in project's root directory (the directory from which tests are run), by running this command:

browserstack-runner init

Parameters for browserstack.json

• username: BrowserStack username (Or BROWSERSTACK_USERNAME environment variable)
• key: BrowserStack access key (Or BROWSERSTACK_KEY environment variable)
• test_path: Path to the test page which will run the tests when opened in a browser.
• test_framework: Specify test framework which will run the tests. Currently supporting qunit, jasmine, jasmine2 and mocha.
• timeout: Specify worker timeout with BrowserStack.
• browsers: A list of browsers on which tests are to be run. Find a list of all supported browsers and platforms on browerstack.com.
• proxy: Specify a proxy to use for the local tunnel. Object with host, port, username and password properties.

A sample configuration file:

{
  "username": "<username>",
  "key": "<access key>",
  "test_framework": "qunit|jasmine|jasmine2|mocha",
  "test_path": ["relative/path/to/test/page1", "relative/path/to/test/page2"],
  "browsers": [
    {
      "browser": "ie",
      "browser_version": "10.0",
      "device": null,
      "os": "Windows",
      "os_version": "8"
    },
    {
      "os": "android",
      "os_version": "4.0",
      "device": "Samsung Galaxy Nexus"
    },
    {
      "os": "ios",
      "os_version": "7.0",
      "device": "iPhone 5S"
    }
  ]
}

Compact browsers configuration

When os and os_version granularity is not desired, following configuration can be used:

• [browser]_current or browser_latest: will assign the latest version of the browser.
• [browser]_previous: will assign the previous version of the browser.
• [browser]_[version]: will assign the version specificed of the browser. Minor versions can be concatinated with underscores.

This can also be mixed with fine-grained configuration.

Example:

{
  "browsers": [
      "chrome_previous",
      "chrome_latest",
      "firefox_previous",
      "firefox_latest",
      "ie_6",
      "ie_11",
      "opera_12_1",
      "safari_5_1",
      {
        "browser": "ie",
        "browser_version": "10.0",
        "device": null,
        "os": "Windows",
        "os_version": "8"
      }
  ]
}

Proxy support for BrowserStack local

Add the following in browserstack.json

{
  "proxy": {
      "host": "localhost",
      "port": 3128,
      "username": "foo",
      "password": "bar"
  }
}

Supported environment variables

To avoid duplication of system or user specific information across several configuration files, use these environment variables:

• BROWSERSTACK_USERNAME: BrowserStack user name.
• BROWSERSTACK_KEY: BrowserStack key.
• TUNNEL_ID: Identifier for the current instance of the tunnel process. In TRAVIS setup TRAVIS_JOB_ID will be the default identifier.
• BROWSERSTACK_JSON: Path to the browserstack.json file. If null, browserstack.json in the root directory will be used.

Secure Information

To avoid checking in the BrowserStack username and key in your source control system, the corresponding environment variables can be used.

These can also be provided by a build server, for example using secure environment variables on Travis CI.
