    grunt-mocha-webdriver

    NPM version Build Status david-dm-status-badge david-dm-status-badge

    A Grunt task that runs Mocha-based functional tests against a Webdriver-enabled source: specifically, PhantomJS for local testing and Sauce Labs for comprehensive cross-browser testing.

    This plugin is a combination of mocha-cloud and grunt-saucelabs. The former library doesn't have Grunt integration built in, and is designed for running tests inside the browser; the latter library can launch a grid of browsers on Sauce Labs, but doesn't support Mocha.

    Getting Started

    This plugin requires Grunt >=0.4.0; connecting to Sauce Labs requires java.

    Install the plugin with:

    npm install grunt-mocha-webdriver --save-dev

    Then add this line to your project's Gruntfile:

    grunt.loadNpmTasks('grunt-mocha-webdriver');

    Using grunt-mocha-webdriver with Phantomjs

    In version 0.9.4 and later, phantom is included via its NPM module. In order to run tests against phantom, simply add the usePhantom flag to the options hash. The plugin defaults to hitting port 4444, but you can specify your own port via the phantomPort option.

    Using grunt-mocha-webdriver with your own Selenium server

    In version 0.9.15 and later, You can run your tests against your own Selenium server instance. To do so, use hostname and port options. Don't forget to remove username and key. Note that the Selenium server should be started and ready before starting the tests.

    Documentation

    Run this task with the mochaWebdriver grunt command. For this plugin, the Grunt src property will specify which test files should be run with Mocha in the mochaWebdriver multitask. These tests should be structured as normal Mocha tests, but should use this.browser to refer to a WebDriver browser which will be injected into the test's context. The browser can be driven with the API specified in WD.js. The default is to use the callback-enabled version of WD.js, but usePromises can be passed as true to switch to the Promise-enabled version.

    As of version 0.2.3 of WD.js, wd provides the ability to add test methods to its default set of capabilities. grunt-mocha-webdriver exposes the wd instance in the same way that browser is exposed, so that you can easily add your own test methods to wd.

    Also, Mocha options are exposed to tests. This is especially helpful if you want to reuse the defined Mocha timeout for your Webdriver tests. For example you can do this in your Webdriver based E2E tests:

    this.browser.waitForElementByCss('.aClass', this.mochaOptions.timeout, cb);

    Please look at this project's Gruntfile and tests to see all that in action.

    Options

    The usual Mocha options are passed through this task to a new Mocha instance. Please note that while it's possible to specify the Mocha reporter for tests running on Phantom and when concurrency is 1 on saucelabs or selenium, the task will default to a custom reporter if concurrency is more than 1 and the browser is not phantom. This restriction is in place to handle concurrent Sauce Labs/Selenium testing sessions, which could pollute the log.

    The following options can be supplied to the task:

    usePhantom

    Type: Boolean

    Specifies whether the task should test against a PhantomJS instance instead of Sauce Labs. Defaults to false. If true, the tests will run against Phantom INSTEAD of running against Sauce Labs.

    phantomPort

    Type: Int (Default: 4444)

    if testing against PhantomJS with the usePhantom flag, specify the port to test against.

    phantomCapabilities

    Type: Object (Default: {})

    if testing against PhantomJS with the usePhantom flag, specify the browser capabilities.

    phantomFlags

    Type: array (Default: [])

    if testing against PhantomJS with the usePhantom command-line options, specify start additional flags to use. Check here or type phantomjs -h for complete list of flags.

    usePromises

    Type: Boolean

    Specifies whether to use the Promise chain version of the WD.js API. Defaults to false (the callback version).

    ignoreSslErrors

    Type: Boolean

    A passthrough to the Phantom CLI runner to ignore errors with SSL certs.

    require

    Type: Array

    An array of paths for requiring before running Mocha tests. Useful for pre-requires that manipulate Mocha's global environment (e.g.g making Sinon globally available).

    username

    Type: String

    The Sauce Labs username to use. Defaults to value of env var SAUCE_USERNAME.

    key

    Type: String

    The Sauce Labs API key to use. Defaults to value of env var SAUCE_ACCESS_KEY.

    secureCommands

    Type: Boolean (Default: false)

    If true, it will use saucelabs, with default hostname set to 127.0.0.1 and port set to 4445 in order to send selenium commands through Sauce Connect tunnel (more info here).

    autoInstall

    Type: Boolean

    If true this will download Selenium and Chrome Driver to run tests locally.

    hostname

    Type: String

    If specified, it will connect that selenium server instead of ondemand.saucelabs.com.

    port

    Type: Int

    Selenium server port. Should be used in conjonction with hostname.

    identifier

    Type: Number

    A Unique identifier for the generated tunnel to Sauce Labs. Will be automatically generated if not specified. Useful for connected to existing Sauce tunnels.

    concurrency

    Type: Int

    The number of concurrent browser sessions to spin up on Sauce Labs. Defaults to 1.

    tunneled

    Type: Boolean A boolean value to indicate if the tunnel is to be created or not.

    tunnelFlags

    Type: Array An array of option flags for Sauce Connect. See the list of available options here.

    testName

    Type: String

    The name of the test, as reported to Sauce Labs.

    testTags

    Type: [String]

    An array of tags to associate with the test, as reported to Sauce Labs.

    browsers

    Type: [Object]

    An array of objects specifying which browser options should be passed to Sauce Labs. Unless a test is run against Phantom (e.g. usePhantom is true), this option must be specified. Each browser hash should specify: browserName. For saucelabs tests, platform, and version are also required.
