I use Jasmine as my JavaScript unit/behavior testing framework of choice because it's elegant and has a good community ecosystem around it. I recently wrote up how to get Jasmine-based autotesting set up with Guard, which is great for development time testing, but what about continuous integration?

Well, it turns out that it's pretty difficult to get Jasmine integrated with Jenkins. This is not because of an inherent problem with either of those two, it's just that no-one got around to writing an open source integration layer until now.

The main problem is that Jasmine tests usually expect to run in a browser, but Jenkins needs results to be exposed in .xml files. Clearly we need some bridge here to take the headless browser output and dump it into correctly formatted .xml files. Specifically, these xml files need to follow the JUnit XML file format for Jenkins to be able to process them. Enter guard-jasmine.

In my previous article on getting Jasmine and Guard set up, I was using the jasmine-headless-webkit and guard-jasmine-headless-webkit gems to provide the glue. Since then I've replaced those 2 gems with a single gem - guard-jasmine, written by Michael Kessler, the Guard master himself. This simplifies our dependencies a little, but doesn't buy us the .xml file functionality we need.
