Karma

Project to learn and experiment with the Karma javascript test runner. Karma runs your javascript tests in multiple browsers.

Quickstart Tutorial

1. Change to project directory

    $ cd ~/projects/karma-playground
   

2. New NPM project

    $ npm init
   

   accept all defaults

3. Install karma

   # Install Karma:
   $ npm install karma --save-dev
   
   # Install plugins that your project needs:
   $ npm install karma-jasmine karma-chrome-launcher --save-dev
   

4. Install global karma cli so we can type karma without the full path from anywhere.

    $ npm install -g karma-cli
   

5. Create sample test.

   Using Jasmine for our example.

   $ mkdir test
   $ touch test/sample1.js
   

   // test/sample1.js
   describe("A suite", function() {
     it("contains spec with an expectation", function() {
       expect(true).toBe(true);
     });
   });
   

6. Generate the karma configuration file

    $ karma init my.conf.js
   

7. Start karma

    # Start Karma using your configuration:
    $ karma start my.conf.js
   

   You’ll see Chrome or the browsers you chose start
