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;
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
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.
