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.
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:
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
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
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
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.
wd instance in the same way that
browser is exposed, so that
you can easily add your own test methods to wd.
Please look at this project's Gruntfile and tests to see it in action.
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, there's only one reporter currently supported for tests against Sauce Labs. This restriction is in place to handle concurrent Sauce Labs testing sessions, which could pollute the log.
The following options can be supplied to the task:
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.
Type: Int (Default: 4444)
if testing against PhantomJS with the
usePhantom flag, specify the port
to test against.
Specifies whether to use the Promise chain version of the WD.js API. Defaults to false (the callback version).
A passthrough to the Phantom CLI runner to ignore errors with SSL certs.
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).
The Sauce Labs username to use. Defaults to value of env var
The Sauce Labs API key to use. Defaults to value of env var
A Unique identifier for the generated tunnel to Sauce Labs. Will be automatically generated if not specified. Useful for connected to existing Sauce tunnels.
The number of concurrent browser sessions to spin up on Sauce Labs. Defaults to 1.
Time to wait before closing all tunnels.
The name of the test, as reported to Sauce Labs.
An array of tags to associate with the test, as reported to Sauce Labs.
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:
