Thank you for sharing. I just read through several of your blog posts and especially resonate with your “evolutionary design”. The idea of integration tests/test harness first over unit tests makes a lot of sense to me too. As a one person team myself, the “art” of creating quality software products, at speed, is revealing itself and is quite fascinating.
It’s not everyday that devs like me get to learn from someone with as much experience as you have. Thanks again for sharing your knowledge!
