Failing at TDD

Someone asked for more clarification about how I failed at TDD... I gave reasons why I failed, but no measurement of success. In the class, I had said that I failed until I finally changed my way of thinking and actually got what test driving is all about...

But I was thinking about this statement on the way home and this isn't true. Even after I understood how to test, my classes under test would outgrow their test fixtures because I wasn't in the habit of writing tests first or the tests were too rigid to change or I just wanted to get something to work really quick without having to write a test... a little extra code here and there eventually leads to a lot of failing tests, ignored tests, ignored assemblies and then total failure...

A few years ago I was lucky enough to have lunch with Bob Martin and we had a long talk about discipline. I would argue that this is the most important attribute for test development (he really knew what he was talking about, how little I knew then).

I finally considered myself successful in TDD when I had several projects that were test driven, and continued to evolve test driven as well... i.e. I was finally successful when my tests were refactored with the rest of my code, my tests continued to drive change and it wasn't painful.
