I feel your comment should be the top one. but I disagree with this bit: > the code base will be better. I'd change "will be" to "might get." because this is true if you're doing unit tests that the code base can use. but sometimes you do characterization tests, which are not worth keeping around. or you might build a couple variations on "hello world" with the unfamiliar code base, just to be sure that it works the way you think it does.
