grunt-contrib-qunit

grunt-contrib-qunit v2.0.0 Build Status: Linux Build Status: Windows

Run QUnit unit tests in a headless PhantomJS instance

Getting Started

If you haven't used Grunt before, be sure to check out the Getting Started guide, as it explains how to create a Gruntfile as well as install and use Grunt plugins. Once you're familiar with that process, you may install this plugin with this command:

npm install grunt-contrib-qunit --save-dev

Once the plugin has been installed, it may be enabled inside your Gruntfile with this line of JavaScript:

grunt.loadNpmTasks('grunt-contrib-qunit');

Qunit task

Run this task with the grunt qunit command.

You have chosen to write your unit tests using [QUnit][], you have written a html page which reports the summary and indivudual details of your unit tests, you are happy with this but realize you miss the ability to have your unit test suite run automatically each time you commit changes to your code.

This is where the grunt-contrib-qunit plugin comes in the play: grunt-contrib-qunit lets you run your tests in the invisible PhantomJS browser, thus converting your unit test suite into something you can run from a script, a script you can have automatically run on travis-ci (or the Continuous Integration service of your choice) which in turn can alert you of any rule-breaking commit to your code.

You can still monitor the status of your unit tests suite visiting your html test page in your browser, but with grunt-contrib-qunit you can also run the same suite from the command line interface.

This plugin defines one single task: qunit. Configure it in your Gruntfile.js, run it with the grunt qunit command.

Please read about specifying task targets, files and options in the grunt Configuring tasks guide.

When installed by npm, this plugin will automatically download and install PhantomJS locally via the grunt-lib-phantomjs library. If your system already provides the PhantomJS program, this plugin will use the globally installed program.

Also note that running grunt with the --debug flag will output a lot of PhantomJS-specific debugging information. This can be very helpful in seeing what actual URIs are being requested and received by PhantomJS.

OS Dependencies

This plugin uses PhantomJS to run tests. PhantomJS requires these dependencies

On Ubuntu/Debian

apt-get install libfontconfig1 fontconfig libfontconfig1-dev libfreetype6-dev

On CentOS

yum install fontconfig freetype

Options

timeout

Type: Number
Default: 5000

The amount of time (in milliseconds) that grunt will wait for a QUnit start() call before failing the task with an error.

inject

Type: String|Array
Default: phantomjs/bridge.js

One or multiple (array) JavaScript file names to inject into the html test page. Defaults to the path of the QUnit-PhantomJS bridge file.

You may want to inject something different than the provided QUnit-PhantomJS bridge, or to inject more than just the provided bridge. See the built-in bridge for more information.

httpBase

Type: String
Default: ""

Create URLs for the src files, all src files are prefixed with that base.

console

Type: boolean
Default: true

Set to false to hide PhantomJS console output.

urls

Type: Array
Default: []

Absolute http:// or https:// urls to be passed to PhantomJS. Specified URLs will be merged with any specified src files first. Note that urls must be served by a web server, and since this task doesn't contain a web server, one will need to be configured separately. The grunt-contrib-connect plugin provides a basic web server.

force

Type: boolean
Default: false

When true, the whole task will not fail when there are individual test failures, or when no assertions for a test have run. This can be set to true when you always want other tasks in the queue to be executed.

summaryOnly

Type: boolean
Default: false

When true, this will suppress the default logging for individually failed tests. Customized logging can be performed by listening to and responding to qunit.log events.

(-- PhantomJS arguments)

Type: String
Default: (none)

Additional -- style arguments that need to be passed in to PhantomJS may be specified as options, like {'--option': 'value'}. This may be useful for specifying a cookies file, local storage file, or a proxy. See the PhantomJS API Reference for a list of -- options that PhantomJS supports.

noGlobals

Type: boolean
Default: false

Fail a test when the global namespace is polluted. See the QUnit cookbook for more information.

Command line options

Filtering by module name: --modules

grunt qunit --modules="foo"

Will run the module foo. You can specify one or multiple, comma-separated modules to run.

Running tests in seeded-random order: --seed

grunt qunit --seed="a-string"

Specify the seed to pass to QUnit, to run tests in random, but deterministic order. See QUnit.config.seed docs for more information.

Note: You must be using QUnit version 1.23.0 or greater for these features to work properly.

Usage examples

Wildcards

In this example, grunt qunit:all will test all .html files in the test directory and all subdirectories. First, the wildcard is expanded to match each individual file. Then, each matched filename is passed to PhantomJS (one at a time).

// Project configuration. 
grunt.initConfig({
  qunit: {
    all: ['test/**/*.html']
  }
});

Testing via http:// or https://

In circumstances where running unit tests from local files is inadequate, you can specify http:// or https:// URLs via the urls option. Each URL is passed to PhantomJS (one at a time).

In this example, grunt qunit will test two files, served from the server running at localhost:8000.

// Project configuration. 
grunt.initConfig({
  qunit: {
    all: {
      options: {
        urls: [
          'http://localhost:8000/test/foo.html',
          'http://localhost:8000/test/bar.html'
        ]
      }
    }
  }
});

Wildcards and URLs may be combined by specifying both.

Using the grunt-contrib-connect plugin

It's important to note that grunt does not automatically start a localhost web server. That being said, the grunt-contrib-connect plugin connect task can be run before the qunit task to serve files via a simple connect web server.

In the following example, if a web server isn't running at localhost:8000, running grunt qunit with the following configuration will fail because the qunit task won't be able to load the specified URLs. However, running grunt connect qunit will first start a static connect web server at localhost:8000 with its base path set to the Gruntfile's directory. Then, the qunit task will be run, requesting the specified URLs.

// Project configuration. 
grunt.initConfig({
  qunit: {
    all: {
      options: {
        urls: [
          'http://localhost:8000/test/foo.html',
          'http://localhost:8000/test/bar.html',
        ]
      }
    }
  },
  connect: {
    server: {
      options: {
        port: 8000,
        base: '.'
      }
    }
  }
});
 
// This plugin provides the "connect" task. 
grunt.loadNpmTasks('grunt-contrib-connect');
 
// A convenient task alias. 
grunt.registerTask('test', ['connect', 'qunit']);

Custom timeouts and PhantomJS options

In the following example, the default timeout value of 5000 is overridden with the value 10000 (timeout values are in milliseconds). Additionally, PhantomJS will read stored cookies from the specified file. See the PhantomJS API Reference for a list of -- options that PhantomJS supports.

// Project configuration. 
grunt.initConfig({
  qunit: {
    options: {
      timeout: 10000,
      '--cookies-file': 'misc/cookies.txt'
    },
    all: ['test/**/*.html']
  }
});

Loading QUnit with AMD

When using AMD to load QUnit and your tests, make sure to have a path for the qunit module defined.

Events and reporting

QUnit callback methods and arguments are also emitted through grunt's event system so that you may build custom reporting tools. Please refer to to the QUnit documentation for more information.

The events, with arguments, are as follows:

  • qunit.begin
  • qunit.moduleStart (name)
  • qunit.testStart (name)
  • qunit.log (result, actual, expected, message, source)
  • qunit.testDone (name, failed, passed, total, duration)
  • qunit.moduleDone (name, failed, passed, total)
  • qunit.done (failed, passed, total, runtime)

In addition to QUnit callback-named events, the following events are emitted by Grunt:

  • qunit.spawn (url): when PhantomJS is spawned for a test
  • qunit.fail.load (url): when PhantomJS could not open the given url
  • qunit.fail.timeout: when a QUnit test times out, usually due to a missing QUnit.start() call
  • qunit.error.onError (message, stackTrace): when a JavaScript execution error occurs

You may listen for these events like so:

grunt.event.on('qunit.spawn', function (url) {
  grunt.log.ok('Running test: ' + url);
});
