JavaScript code coverage with Jasmine

Question

We are planning to introduce JavaScript unit testing in our project and so far Jasmine appears to be one of the better BDD unit testing frameworks for JavaScript. Now I am wondering how can we monitor code coverage of our JavaScript code. Are there any tools/plugins that we could use? We are a Microsoft shop and use .NET/MVC 4.

Solution 1

There is the Istanbul code coverage tool. And, as there is a grunt plugin for Istanbul/Jasmine it should work with Jasmine.

Solution 2

A quick Googling turns up this blog post evaluating a bunch of options: Istanbul, Karma, Blanket.js, and JSCover.

For Rails, the jasmine-coverage (based on JSCoverage) gem gives you a Rake task that generates output in different formats

Solution 3

May be a little bit late, but if test coverage is important, you can also try mocha which has a built-in support for test coverage, a good reputation too, a syntax close to jasmine and a good integration (grunt, karma, ...)

+1 for Mocha. I use both Jasmine and Mocha, and they do have a similar feel. Mocha + ShouldJS makes for a very flexible testing framework.
