grunt-contrib-nodeunit v3.0.1 Build Status

Run Nodeunit unit tests

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-nodeunit --save-dev

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


Nodeunit task

Run this task with the grunt nodeunit command.

Task targets, files and options may be specified according to the grunt Configuring tasks guide.

This plugin provides server-side JavaScript unit testing via nodeunit. If you're looking to test JavaScript that uses window or the DOM, please use the grunt-contrib-qunit pluginqunit task.

Differences from Nodeunit Command Line

There may be a few differences versus running nodeunit on the command line:

Undone tests will cause problems

Nodeunit's reporters (such as default) are in charge of tracking tests that do not complete. They often hook into process.on('exit'). Since grunt is handling the runtime, it does not exit, so the reporter's clean-up code that monitors undone tests does not fire. Additionally, the reporters do not expose the number of "Undone" tests in their completion callbacks.

This can cause problems. For example, if an exception is thrown in an undone test, the exception might bubble up into the grunt runtime if it's still running. This would cause grunt to exit, while nodeunit command line would show the undone test.

If you're getting strange grunt runtime errors or seeing grunt exit, check for "undone" tests.



Type: String
Default: 'grunt'

Specifies the reporter you want to use. For example, default, verbose or tap.


Type: Boolean
Default: false

Specifies the file the reporter's output should be saved to. For example, tests.tap.


Type: Object
Default: {}

Specifies the options passed to the reporter. For example, the junit reporter requires the output option to be set:

  nodeunit: {
    all: ['test/*_test.js'],
    options: {
      reporter: 'junit',
      reporterOptions: {
        output: 'outputdir'

Usage examples


In this example, grunt nodeunit:all or grunt nodeunit will test all files ending with _test.js in the test directory.

  nodeunit: {
    all: ['test/*_test.js']

With a slight modification, grunt nodeunit:all will test files matching the same pattern in the test directory and all subdirectories.

  nodeunit: {
    all: ['test/**/*_test.js']

Using Other Reporters

To use a reporter other than the default one, you can specify the reporter and reporterOutput parameters.

  nodeunit: {
    all: ['test/*_test.js'],
    options: {
      reporter: 'tap',
      reporterOutput: 'tests.tap',
      reporterOptions: {
        output: 'outputdir'
