Please, correct me if I am wrong, but the process he described is completely against TDD and no wonder it did not work (they wrote the function first, and added tests later, lot of tests, in TDD you would have rather more shorter functions with a few tests for each): - Function A is 147 lines long. It is the simple core of the program. - Function A is committed to the repository on June 26th, 2002. Function A has four test cases. Nevertheless, a bug is found in Function A on the 28th and a patch is uploaded on July 6th. It contains two new test cases. - This continues a bit. However, by August 2002, function A is mostly stable and has no fewer than thirteen test cases--mainly for fencepost errors and other idiotic things anyone can find with a stack trace. Except for a blip in early 2003, function A, now 152 lines long, is unchanged until mid-2006.
