Why We Refactored JUnit

Bill Venners writes "In this article, three programmers tell the story of how their frustration with JUnit's API led to the creation of Artima SuiteRunner, a free, open source test toolkit and JUnit runner. These programmers simply wanted to create a small add-on tool to JUnit, but found JUnit's design non-intuitive and API documention poor. After spending time reading through JUnit's source code and attempting to guess at the API contracts, they gave up and rewrote it."
