I recently broke a unit test by adding one entry to a hash constant (a list of acceptable mime types and their corresponding file extensions). I looked at the test, and it was just comparing the defined constant, to a hardcoded version of itself. I rewrote the test by converting the constant to a string, taking a checksum of it, and comparing _that_ to a short hardcoded value. Now the test is just 1 line of code, instead of 41! Then I put it through code review, and my team said "What a ridiculous test." But they didn't see any problem in the previous version that compared it to a 40-line hardcoded hash. It's a weird world.
