  1. The thing I often not be used enough is hierarchical test. In your example you can have a few tests that if they pass everything works. Only if they fail the more detailed tests need to be run (automatically) to find where. Before anyone screams with me.. real world is not always web development, there are systems where some tests take HOURS because they operate over a Terabyte of data each time. It is important to not waste time and server costs to run something that is not needed.

  2. That said a modern engine has built in self monitoring. That is what unit test would be in that scenario. That said , it is true, You cannot write ALL the tests before you advance a bit in your development, it is as bad as writtign ALL the code before writting any test.
