Summary: <p>With conventional TDD, you write a failing test, get it to pass, then refactor.<br> Then run the tests again to make sure your refactoring didn't break anything.<br> But what if it did break something? <br> Kent Beck has been recommending to commit your code to revision control after every green test run.<br> Oddmund Strømme suggested a symmetrical idea to go ahead and revert the code when a test fails.<br> Kent writes that he hated the idea, but had to try it.<br> Then wrote about it last September.<br> And now we have TCR, "(test && commit) || revert".</p> <p>What's it feel like to actually do this?<br> Well, Thomas Deniffel has been using it since about a month after that article came out.<br> In this episode, we'll hear from Thomas about his experience with it.</p> <p>It's a fascinating idea. Have a listen and let me know what you think.</p><p>Special Guest: Thomas Deniffel.</p><p>Sponsored By:</p><ul><li> <a rel="nofollow" href="http://testandcode.com/pycharm">PyCharm Professional</a>: <a rel="nofollow" href="http://testandcode.com/pycharm">Try PyCharm Pro for an extended 4 month trial before deciding which version you need.
