Running QUnit tests using continuous integration
On my current project we will be using QUnit to writing tests for our JavaScript. What would be really nice is if our CI build could run JavaScript unit tests.
Well, it can! It only takes a few magic potions and sacrificing a few small animals.
Luckily someone had done this before and blogged about it so I pretty much just had to follow instructions. Here’s the long and short of it:
- We had to get WatiN, which will be used to create an instance of Internet Explorer that will run our HTML page with the QUnit tests in it.
- We had to get the IterativeTest addin for NUnit. This will create one NUnit test for each QUnit test.
In the code, I added an IterativeTest (a test decorated with the [IterativeTest] attribute) that will run all of the QUnit tests. Since we all use ReSharper and ReSharper doesn’t recognize the [IterativeTest] attribute, I also added a normal NUnit [Test] that will run all of the QUnit tests inside one test and fail if any of the QUnit tests fail. So we should have all of our bases covered.
