Subject RE: Unit test code in HARMONY-16
Date Mon, 16 Jan 2006 04:42:02 GMT
Hi George

We will remove all the tests and these QA guys will never disturb us :)

Every time we remove a test we leave something untested.

For example, SerializationTest is a base for all the tests that check 
serialization compatibility, and if we remove it because we do not 
think about serialization right now we will lose that compatibility.

The same for performance, it is of importance still. Existing test suite
allows us seeking performance regressions. Otherwise we will have
to keep in sync two parallel test suites - one PerformanceTest based
just for testing the performance and another one - for unit testing.

So, what is the noise? GUI is thinking that those base classes are
tests?
Maybe it makes sense to rename PerformanceTest to e.g. PerformanceTost
and GUI will be happy?

Thanks,
Mikhail Loenko
