NUnit TestCase
By Thomas Johnson | March 3, 2009
In my previous post about fitnesse I mentioned that it would be good to have a simple way to specify expected inputs and outputs for a method. I was fairly sure there must be something out there and the latest version of NUnit (Beta version 2.5) offers a great solution.
It allows us to specify parameters for a test method in a way which provides great flexibility. Here you can see how easily we’re able to supply the data for different test cases … the tests run as if you had set up seperate methods for each case.
You can also use a result parameter to specify an expected return value as follows: This is great … a clear and concise way to setup multiple test cases for simple tests. If the test setup is more complicated it may not workout out so nicely. I believe other unit test frameworks provide similar functionality so have a look around.
