Jasmine and Karma
Let's talk about testing again, and will surely again in the future :) Last time I introduced the JavaScript Testing with Jasmine and we ran a few specs, however it seemed some how half baked - you were required to create a special page and open it in the browser to see the results. I you wanted to check in various browsers, you should have iterated the same procedure on each browser again and again. This is not how we do things in 2014! We want to streamline the process! This is where Karma comes. It is built on Node.js and allows you to run the tests of your front end code automatically on various browsers. Installation In order to install Karma on your computer, run the following npm command. If you're not familiar with the tool, please read the JavaScript Developer Toolkit article first: npm install -g karma After you try to call karma though, you'll get unknown command error, which can be easily solved by installing karma command-line interface ( CLI )
