Do you write your unit tests before or after coding a piece of functionality? [closed]

Answer 1

I tend to use unit tests to test the code as I'm writing it. That way I'm using what I'm writing at the same time, as I use the unit test to test code while I'm writing it. Much like a console app would.

Sometimes I've even written tests without asserts, just debug outputs, just to test that how I use something is working without exceptions.

So my answer is, after a little bit of coding.
