Not long after the Christmas break between 2001 and 2002 I wrote “JUnit: A Starter Guide” in response to a flurry of complaints over the lack of a decent JUnit tutorial. I didn’t know at the time that I would turn this simple tutorial, written somewhat in haste, into JUnit Recipes: Practical Methods for Programmer Testing, which I completed in 2004. It has surprised me to note that several hundred people continue to read the Starter Guide, so I thought I would include a link to it from here. In order not to deal with differences in HTML formatting, I have decided to link to the document as a PDF and keep it mostly for historical purposes. Much has changed since 2002, and I hope the Starter Guide remains a solid introduction to JUnit, test-driven development and software design.
