Hi,

I've discovered a "minor" design flaw in my NUnit generator under 
development (same as previously discussed here).

The generator generates two main outputs (if XML output is activated):

- The "target name".nunit file, used to detect if the tests are up-to-date 
and were run successfully.
- The XML report, used to store details on tests run and their success.

Now, when one or more of the tests fail at runtime, the XML report is 
deleted as well - which is obviously not what I'd like. What would be the 
best design for allowing to leave the XML report behind, if:

1. The tests are actually run (no problems with e.g. the test runner not 
being able to find or load the shared libraries containing the tests, or 
their runtime dependencies).
2. One or more of the tests fail at runtime (the test runner then exits with 
a non-zero status code).

If (1) above fails, i.e. there is a problem with the actual runner 
execution, I think the XML report should get deleted as no tests were 
actually created.

Any comments / design suggestions?
