grunt-contrib-jasmine v4.0.0 Build Status

Run jasmine specs headlessly through Headless Chrome

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-jasmine --save-dev

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

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

Jasmine task

Run this task with the grunt jasmine command.

Automatically builds and maintains your spec runner and runs your tests headlessly through Headless Chrome.

Run specs locally or on a remote server

Run your tests on your local filesystem or via a server task like grunt-contrib-connect.

Customize your SpecRunner with templates

Use your own SpecRunner templates to customize how grunt-contrib-jasmine builds the SpecRunner. See the wiki for details and third party templates for examples.

AMD Support

Supports AMD tests via the grunt-template-jasmine-requirejs module

Third party templates

Options

src

Type: String|Array

Your source files. These are the files that you are testing. If you are using RequireJS your source files will be loaded as dependencies into your spec modules and will not need to be placed here.

options.specs

Type: String|Array

Your Jasmine specs.

options.vendor

Type: String|Array

Third party libraries like jQuery & generally anything loaded before source, specs, and helpers.

options.helpers

Type: String|Array

Non-source, non-spec helper files. In the default runner these are loaded after vendor files

options.styles

Type: String|Array

CSS files that get loaded after the jasmine.css

options.version

Type: String Default: 'latest'

This is the version of Jasmine which will be used. Available versions are published to npm.

options.tempDir

Type: String Default: .grunt/grunt-contrib-jasmine

The temporary directory that runners use to load jasmine files. Automatically deleted upon normal runs.

options.outfile

Type: String
Default: _SpecRunner.html

The auto-generated specfile that Headless Chrome will use to run your tests. Automatically deleted upon normal runs. Use the :build flag to generate a SpecRunner manually e.g. grunt jasmine:myTask:build

options.keepRunner

Type: Boolean
Default: false

Prevents the auto-generated specfile used to run your tests from being automatically deleted.

options.junit.path

Type: String
Default: undefined

Path to output JUnit xml

options.junit.consolidate

Type: Boolean
Default: false

Consolidate the JUnit XML so that there is one file per top level suite.

options.junit.template

Type: String
Default: undefined

Specify a custom JUnit template instead of using the default junitTemplate.

options.host

Type: String
Default: ''

The host you want Headless Chrome to connect against to run your tests.

e.g. if using an ad hoc server from within grunt

host : 'http://127.0.0.1:8000/'

Without a host, your specs will be run from the local filesystem.

options.template

Type: String Object
Default: undefined

Custom template used to generate your Spec Runner. Parsed as underscore templates and provided the expanded list of files needed to build a specrunner.

You can specify an object with a process method that will be called as a template function. See the Template API Documentation for more details.

options.templateOptions

Type: Object
Default: {}

Options that will be passed to your template. Used to pass settings to the template.

options.polyfills

Type: String|Array

Third party polyfill libraries like json2 that are loaded at the very top before anything else.

options.display

Type: String
Default: 'full'

options.allowFileAccess

Type: Boolean Default: false

Launches puppeteer with --allow-file-access-from-files (Fix Issue https://github.com/gruntjs/grunt-contrib-jasmine/issues/298)

options.timeout

Type: Number Default: 30000

Change the puppeteer default timeout value in milliseconds (reference: https://github.com/puppeteer/puppeteer/blob/master/docs/api.md#pagesetdefaulttimeouttimeout)

options.sandboxArgs

Type: Object Default: { args: [] }

Pass arugments to puppeteer launcher. For the list of available options, please look at puppeteer launch options.

Example sandboxArgs object:

{
  args: {
    '=-allow-file-access-from-files'
  },
  executeablePath: '/some/other/path/to/chrome'
}

options.summary

Type: Boolean
Default: false

Display a list of all failed tests and their failure messages

Flags

Name: build

Turn on this flag in order to build a SpecRunner html file. This is useful when troubleshooting templates, running in a browser, or as part of a watch chain e.g.

watch: {
  pivotal : {
    files: ['src/**/*.js', 'specs/**/*.js'],
    tasks: 'jasmine:pivotal:build'
  }
}

Filtering specs

filename grunt jasmine --filter=foo will run spec files that have foo in their file name.

folder grunt jasmine --filter=/foo will run spec files within folders that have foo* in their name.

wildcard grunt jasmine --filter=/*-bar will run anything that is located in a folder *-bar

comma separated filters grunt jasmine --filter=foo,bar will run spec files that have foo or bar in their file name.

flags with space grunt jasmine --filter="foo bar" will run spec files that have foo bar in their file name. grunt jasmine --filter="/foo bar" will run spec files within folders that have foo bar* in their name.

Example application usage

Basic Use

Sample configuration to run Pivotal Labs' example Jasmine application.

// Example configuration
grunt.initConfig({
  jasmine: {
    pivotal: {
      src: 'src/**/*.js',
      options: {
        specs: 'spec/*Spec.js',
        helpers: 'spec/*Helper.js'
      }
    }
  }
});

Supplying a custom template

Supplying a custom template to the above example

// Example configuration
grunt.initConfig({
  jasmine: {
    customTemplate: {
      src: 'src/**/*.js',
      options: {
        specs: 'spec/*Spec.js',
        helpers: 'spec/*Helper.js',
        template: 'custom.tmpl'
      }
    }
  }
});

Supplying template modules and vendors

A complex version for the above example

// Example configuration
grunt.initConfig({
  jasmine: {
    customTemplate: {
      src: 'src/**/*.js',
      options: {
        specs: 'spec/*Spec.js',
        helpers: 'spec/*Helper.js',
        template: require('exports-process.js'),
        vendor: [
          'vendor/*.js',
          'http://ajax.googleapis.com/ajax/libs/jquery/1.11.0/jquery.min.js'
        ]
      }
    }
  }
});

Passing options to sandbox (puppeteer)

See puppeteer launch options for a complete list of arguments.

// Example configuration
grunt.initConfig({
  jasmine: {
    customTemplate: {
      src: 'src/**/*.js',
      options: {
        specs: 'spec/*Spec.js',
        helpers: 'spec/*Helper.js',
        template: 'custom.tmpl',
        sandboxArgs: {
          args: ['--no-sandbox'],
          timeout: 3000,
          defaultViewport: {
            isMobile: true
          }
        }
      }
    }
  }
});

Sample RequireJS/NPM Template usage

// Example configuration
grunt.initConfig({
  jasmine: {
    yourTask: {
      src: 'src/**/*.js',
      options: {
        specs: 'spec/*Spec.js',
        template: require('grunt-template-jasmine-requirejs')
      }
    }
  }
});

NPM Templates are just node modules, so you can write and treat them as such.

Please see the grunt-template-jasmine-requirejs documentation for more information on the RequireJS template.

Keeping temp files in an existing directory

Supplying a custom temp directory

// Example configuration
grunt.initConfig({
  jasmine: {
    pivotal: {
      src: 'src/**/*.js',
      options: {
        keepRunner: true,
        tempDir: 'bin/jasmine/',
        specs: 'spec/*Spec.js',
        helpers: 'spec/*Helper.js'
      }
    }
  }
});
