TDD FTW!Originally posted by voodooflux View PostRight, early(ish) night called for I think - I have to test a particularly gnarly piece of code in the morning, and I'll need my wits about me.
Sleep well folks
You probably know already, but Test Driven Development: first you write the tests, which all fail because you haven't written the code yet. However, given that the tests check everything the code should and shouldn't do, you then write the code. When all the tests pass, you've finished
Then somebody finds a case where the code does something you hadn't anticipated. So you devise a test for this unanticipated circumstance, which of course fails because you haven't fixed the bug yet.
Then you fix the bug. If all the tests now pass, win. If some other test now fails, your fix has introduced a regression, so you need to re-address the issue. (You do have a version control system that allows you to backtrack, don't you?)
You may then find that the code has to be refactored to allow the fix to be implemented. So you refactor the code, then run the tests, and it all works except for the existing fail. Now you can implement the fix for the existing fail, and if all the tests now run successfully, then once again you're done.
Apart from many other benefits, it's also a good way of avoiding the temptations of premature optimisation and feature creep
It was for not being seen to have grasped these facts (which I grasped around 1999) that I got knocked back for that contract last week
Still, TDD FTW!
