This is such a short post, but full of good advice.
Newbies should get feedback and be open to learning. Actually, experts also. Most of them became expert this way.
Learning TDD, like everything, is a process. Pick up the good habits, one or few at a time, and do not try everything at once – small victories.
And for some comments on the original blog post – I believe the post should be read as an opportunity for improvement, not disparaging the newbie’s level of knowledge.
