grunt-cafe-mocha

A Grunt plugin for running server-side Mocha tests that actually works.

Getting Started

This plugin requires Grunt ~0.4.1

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-cafe-mocha --save-dev

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

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

This plugin requires npm ~1.4.6

In practice, this should only be a problem if you are targeting Node 0.8. In this case, you will need to upgrade npm manually using a command like this:

npm install -g npm@~1.4.6

The "cafemocha" task

Overview

In your project's Gruntfile, add a section named cafemocha to the data object passed into grunt.initConfig().

grunt.initConfig({
  cafemocha: {
    testThis: {
        src: 'test/this/**/*.js',
        options: {
            ui: 'bdd',
            require: [
                'should',
            ],
        },
    },
 
    /// Any number of tests here...
 
    testThat: {
        src: 'test/that/*.js',
        options: {
            ui: 'tdd',
            growl: true,
            reporter: 'nyan',
        },
    },
  },
})

Options

options.require

Type: List

Default value: []

A list of modules to load before running the tests.

options.reporter

Type: String

Default value: 'list'

A string value to pick which reporter to use when testing. To see a list of all the reporters, check here.

If using the reporter html-cov or json-cov, take a special look at the coverage option.

options.ui

Type: String

Default value: 'bdd'

A string value to pick which type of user-interface to use. The options are bdd, tdd, or exports. Read more about interfaces here.

options.grep

Type: String to be turned into a RegExp

Default value: .*

A string value to run tests that only match the given pattern. For example, if the Mocha test file has the tests: test1, test2, test3, test4, if options.grep = 'test[12]', it will only match the first two tests and run them.

options.invert

Type: Boolean

Default value: false

Either true or false that will either match invert the matching. Using the example from the section for options.grep, setting this option to true would result in the last two tests being ran, but not the first two.

options.timeout

Type: Integer

Default value: 2000

The tiemout time for a test-case in milliseconds.

options.slow

Type: Integer

Default value: 75

Threshold for a "slow" test in milliseconds.

options.colors

Type: Boolean

Default value: undefined

True forces the enabling of colors while false forces the disabling of colors.

options.growl

Type: Boolean

Default value: false

Enable Growl/OS X (10.8) notification system on test completion.

options.bail

Type: Boolean

Default value: false

Bail after the first test failure.

options.globals

Type: List

Default value: []

A list of globals names.

options.ignoreLeaks

Type: Boolean

Default value: false

Ignore global variable leaks

options.coverage

Type: Boolean | Object

Default value: false

Turns on the coverage feature. If options.coverage is set to true, the following defaults are used:

{
    output: 'coverage.html',
    env: 'COV'
}

To override the defaults, just pass in an object like so:

coverage: {
    output: 'coverageTwo.html',
    env: 'ENHANCED_COVERAGE',
}

The output option is a path to where the coverage output will be saved to.

The env option is the name of the process.env variable to set to a truthy value. For example, if coverage.env = 'ENHANCED_COVERAGE' then in your project, process.env['ENHANCED_COVERAGE'] will be truthy.

Check out the Coverage Example for more details.

Usage Examples

Basic Behavioral-driven Development

grunt.initConfig({
  cafemocha: {
    src: 'test/**/*.js',
    options: {
        ui: 'bdd',
    },
  },
})

Basic Test-driven Development

grunt.initConfig({
    cafemocha: {
        src: 'test/**/*.js',
        options: {
            ui: 'tdd',
        },
    },
});

Require More Modules

grunt.initConfig({
    cafemocha: {
        options: {
            require: ['should', 'something', 'else', 'here'];
        },
        src: 'test/**/*.js'
    },
});

More Tests

grunt.initConfig({
    cafemocha: {
        foo: {
            src: 'test/foo/*.js',
            options: {
                ui: 'tdd',
            },
        },
 
        bar: {
            src: 'test/bar/*.js',
            options: {
                ui: 'bdd',
            },
        },
    },
});

Coverage Example

The complete example of this is included in the example/ directory.

grunt.initConfig({
    cafemocha: {
        // Setting 'coverage' option to true, using defaults
        coverageOne: {
            src: 'test/*.js',
            options: {
                ui: 'bdd',
                reporter: 'html-cov',
                coverage: true,
                require: [
                    'should',
                ],
            },
        },
 
        // Setting 'coverage' option to an object, overriding defaults
        coverageTwo: {
            src: 'test/*.js',
            options: {
                ui: 'bdd',
                reporter: 'html-cov',
                coverage: {
                    output: 'coverageTwo.html',
                    env: 'ENHANCED_COVERAGE',
                },
                require: [
                    'should',
                ],
            },
        }
    },
});
