I'd definitely consider it. It's by the man who invested the concept of TDD and the xUnit framework after all :-) My experience is that people tend to split into two camps. One group prefers Kent's book - which is kind of like the K&R of TDD. It's thin and very to the point, but needs a bit of work from the reader to get the best out of it. The examples are deliberately simple to express the concepts clearly. The other prefers David Astel 's "Test-driven Development: A Practical Guide". It's a bit more grounded in real world examples, which some folk seem to find an easier way to get a grip on the concepts. Another thing to bear in mind that they both talk about "old" versions of JUnit - before they rebuilt it based on attributes - so you're probably going to want to look at something that covers the latest JUnit or TestNG or something (I'm not a Java hacker by trade - so can't really comment on what the best testing environment is there these days).
