He shows that “some” automated testing can be good. I’d agree:

This is a really interesting point. He’s talking about Load Testing exclusively. And NONE of the bugs he found (some rather severe) would have been uncovered by code-level Unit Tests!
To be fair, it’s unlikely a beta test site would have uncovered these issues, either. Not enough load.
I guess the lesson here is that you can’t expect to attack testing through any one method. A combination of multiple methods is necessary to ensure proper coverage!
