J. B. (Joe) Rainsberger is a Canadian software development consultant and technology writer, best known for his contributions to agile development, for which he was awarded the highest honor from the agile community, the Gordon Pask Award in 2005 (its first year of existence). He is the founder of XPDay North America. He is also well known for his book, JUnit Recipes : Practical Methods for Programmer Testing. He has been an agile practitioner since 2000, and in this time his articles on agile development have been published by leading programmer's magazines including IBM developerWorks and IEEE Software, for the latter of which he edits the regular "Not Just Coding" column.
JUnit Recipes : Practical Methods for Programmer Testing (2004) ISBN 1-932394-23-0 is (as of 2007) the best selling work on unit testing with the popular JUnit framework. It was described as "highly recommended" by the ACM Computing Review magazine, and is considered a "standard reference" for JUnit users. Brad Appleton says in his review at StickyMinds, "'JUnit Recipes' should probably be mandatory reading for anyone using Java, J2EE, and JUnit in the real world." Lasse Koskela says at Java Ranch, "Joe has managed to put out something that I believe will be known as the unofficial JUnit bible for years to come."
