Subject RE: Unit test code in HARMONY-16
Date Mon, 16 Jan 2006 12:05:43 GMT
Hi Mikhail, 

Writing out a JUnit progress update to the console as the tests run 
informing me which test is running is, I think you will agree, not really 
adding much to the overall test experience for most developers. This is 
because JUnit actually does a pretty good job of letting me know which 
test is currently running on its own in addition to providing information 
on any failures. So allow me to repeat a point made in my previous post on 
this topic that appears to have been missed : if additional text output is 
required during a unit test run then why not use a *decorator* class to do 
this instead of baking it in near the top of the class inheritance 
hierarchy ?

As things stand right now, everyone will be forced to see hundreds of  "== 
I am in test XXX ===" output written to their console irrespective of 
whether they are actually currently assessing performance. Why make 
writing out performance messages *mandatory* when running unit tests ? 

That was the central issue raised in my previous post - not a request to 
remove test cases. Thank you for giving me the opportunity to make it once 

Best regards, 
George C. Harley

RE: Unit test code in HARMONY-16

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
Maybe it makes sense to rename PerformanceTest to e.g. PerformanceTost
and GUI will be happy?
