Testing is an expense. Many developers perform rigorous developer tests and use tools like the coverage profiler and debugger and assertions but the problem with these tools is that they are intrusive. How many times have you stepped through problem code in the debugger only to have it work and the have the exact same code fail when the debugger is not open. Basically the debugger, or assertions does not test an application in the same environment that a user running the software (or a third party tool) will test the software. Usually the testing done by developers is sufficient and simply being aware of the fact that enterprise wide automated testing tools don't exist for VFP our developer testing is far more comprehensive than in other languages. That said, the points you raise are valid in my opinion and I too would have hoped for more feedback from others on this topic.
