TDD Goodness

time to read 1 min | 184 words

I just had a complete surprise writing a test for Rhino Mocks. I'm doing that completely Test First, and I wrote a test, expecting it to fail. But it passed. Apperantly I'm already covering this case. :-)

This is so nice.

[Update: (five minutes later) Now it begins to be scary. I just wrote another test, for a part that I knew should be hard to get working. And it passed as well. The code handles it just fine, even though I thought I would need extensive changes to get it to work. I'm talking about ~1,300 LOC, and it still manages to surpirse the hell out of me.]

kpvleeuwen, I agree, unfortunately I don't have anyone to ask off the top of my head. Thanks, I fixed the headers.
