      In my experience, it depends. Some defects are easy to diagnose. Some are instances of user error.

      If you have Programmer Test coverage and QA still finds defects, then the programmers aren't using QA's tests, and they probably should. QA is automating the tests, right? (I hope so.)

      If QA raises a defect, I ask the finder to work with me to reproduce it. I then isolate the cause, write the appropriate missing Programmer Tests, fix the problem and off we go.

      This is not really a testing consideration. It's a logging consideration, and logging is important in enterprise-scale applications where it is usually impossible to run your tests at the client site. I would log information at the key handoff points between components. Within a component, there should be tests. Presumably you only need to know that XML strings are coming into a component because you fear that they are not what the target component expects. Consider using XML schema here to avoid the prob lem.

      It is, by the sound of it.
