This is the way. It's also very important to automate as much of this verification as possible into the harness, rather than sit there and prod it in the chat.

This is the way. It's also very important to automate as much of this verification as possible into the harness, rather than sit there and prod it in the chat. Of course some things are not auto verifiable, and you'll have to give human judgement and input there, but you'll save a lot more time if you spend 1 week painstakingly writing checks for as many little things as possible and integrating them into the harness.
