JUnit vs. Fitnesse

JUnit is for unit testing, Fitnesse for acceptance and functional testing. But in projects we have detected that sometimes JUnit and Fitnesse tests overlap. Sometimes Fitnesse tests are smaller and easier to comprehend than JUnit tests – even for single classes.

I did some very simple experiments to get a better feeling when to use JUnit and when to use Fitnesse tests. The sample code can be downloaded and the results of the experiments are documented in a small article.
