I used to write the tests while developing my software, but I stopped it because I noticed that, almost always, the first api and structures I thought great turn out to be clumsy after some progress. I would need to rewrite the entire main program and the entire test every time.
I believe this situation is common in reality. So my questions are:
- Is it really common to write tests at first, like so said in TDD? I'm just an amateur programmer so I don't know the real development world.
- If so, do people rewrite the tests again (and again) when they revamp the software api/structure? (unless they're smart enough to think up the best one at first, unlike me.)
