jasmine-node: command not found

Jasmine is an independent unit testing framework for effectively testing JavaScript components in a behavior-driven development architecture.

Installing jasmine-node on Unix and Linux

First, you need to install the jasmine-node package. Type the following into your terminal:

$ sudo npm install -g jasmine-node

The -g flag installs jasmine-node on your system globally. Leave the flag off if you’d prefer to keep it in a project directory. This also (probably) means you don’t need sudo at the front.

Basic Usage

Now you have jasmine-node installed! Use it as follows:

$ jasmine-node /path/to/project/directory

Jasmine-node requires you to put your specs in a directory called spec and for the specs in that directory to end with .spec.js. You can also put specs in subdirectories of the spec directory.

For example, if you have a function like this in src/test.js:

global.hello = function() {
    return 'world';
};

A test spec for that might look like this:

// Include what we need to include: this is specific to jasmine-node
require("../src/test.js");

describe("hello", function() {
    it('returns "world"', function() {
        expect(hello()).toEqual("world");
    });
});

Other than the required calls you need to make, the specs are just like browser-based Jasmine specs—except for one asynchronous component.

If you encounter the below error while running the jasmine-node command:

jasmine-node: command not found

you may install it using the below commands as per your choice of distribution.

Jasmine and Ruby on Rails

1. First, you’ll need to add Jasmine to your Gemfile, like so:

gem "jasmine"

2. Next, let’s install it:

bundle install
rails generate jasmine:install

jasmine-node and CoffeeScript

If you want to use jasmine-node with CoffeeScript, you can. You’ll need to end your filenames with .spec.coffee and then run jasmine-node with the –coffee flag, like so:

$ jasmine-node /path/to/project/directory --coffee
