Best books about TDD

I'd like to enhance my TDD knowledge and practice. What would you recommend to read?

From stackoverflow rafek

• I would recomend Test Driven Development: By Example , and reviews on Amazon are good.

  From Espo

• I would recommend Test Driven Development: By Example

  Test-Driven Development: A Practical Guide is pretty good too.

  From aku

• Extreme Programming Explained by Kent Beck. This will give you the basics about why pair-programming and writing tests upfront is the way to go.

  From graham.reeds

• In addition the books listed, I have also read and enjoyed: -

  • Pragmatic Unit Testing In C# with NUnit - The Pragmatic Programmers
  • Test-Driven Development in Microsoft.NET - Microsoft Professional

  But it would also be good for you to look at: -

  • xUnit Test Patterns - Addison Wesley

  As this book contains lots of interesting information on patterns used whilst refactoring tests.

  From AidenMontgomery

• Michael Feather's Working Effectively with Legacy Code provides a wealth of great examples and ideas for how to make code testable. Ideal for those situations you will face when you find yoursel thinking "well, how on earth can I test this?"

  Kent Beck's classic Test-Driven Development - By Example is a good read, quite witty and entertaining.

  If you want something dry but staggeringly comprehensive, which also helps with muscle-building, consider Gerard Meszaros' xUnit Test Patterns - Refactoring Test Code.

  Test-Driven Development in Microsoft .NET is an OK read, but somewhat wed to the DataSet style of doing data access, which seems a bit old school these days.

  From Ian Nelson

• David Astel's Test Driven Development: A practical guide is less dry than Kent Beck's Test Driven Development: By Example which actually isn't bad read. Both Kent and David are great speakers you may want to check some of their talks.

  From John Nolan

• Test Driven Development: By Example and Extreme Programming Explained, both by Kent Beck, are IMHO the Bibles of TDD.

  From Chris B-C

• G'day,

  While not a book Kent Beck's IT Conversations talk about TDD, and other things, is really interesting.

  cheers, Rob

  From Rob Wells
• • Test Driven Development By Example : Kent Beck From THE MAN himself. Lucid, short, to the point - I wish I had his clarity when he works his magic with TDD.
  • Extreme Programming Adventures in C# : Ron Jeffries Fly on the wall look at how it works in the wild - Solo account though by Ron as he builds himself a thingmajig
  • Refactoring : Martin Fowler, Beck, et.all You will be seriously handicapped without this one. This is the third and most often forgotten leg of the TDD stool

  I have Dave Astel's TDD a Practical guide on my To-Read shelf. Hear its good. This set should get you started, then you could progress to go into what makes good tests (Pragmatic Unit testing), continuous Integration... towards XP:Embrace Change.

  From Gishu

• If you're a Java developer, I'd recommend Test Driven:TDD and Acceptance TDD for Java developers. Even if you don't come from Java background, it should be an interesting read.

  From Sandman

• I recommend the Astels first, and then go back to the Beck for deeper understanding. Oh, and there's this in progress (sorry, couldn't resist).

  From Steve Freeman

• Growing Object-Oriented Software Guided by Tests

  It is future classics like Test-driven development: by example

  And new classics about refactoring: Refactoring to patterns
