Dyre Tjeldvoll commented on DERBY-3445:
---------------------------------------

Patch file: 3445-singletest-diff
Committed revision 633135.

Thank you for the patch Vemund. Yes, I did get it to work. I was using ant 1.7, 
but I also needed to set ANT_HOME to ant 1.7. And, as you point out, I needed 
to set the classpath manually. I was a bit surprised by this as I had expected 
it to use classes or jars by default, and let you override as necessary. 
Setting it explicitly works fine, though.

I even ran CacheSessionDataTest with emma and could confirm that all methods 
(except toString()) in the class I added for DERBY-3192 (PiggyBackSessionData) 
had been executed. Nice!

> It is a bit tricky to use EMMA to measure code coverage for the derby testing.
> Modifications must be made to the source both to avoid problems with the 
> SecurityManager and individual tests. It would be good if these modifcations 
> could be done once and for all so that it was easier for anyone to run the 
> tests with EMMA.
> It would also be good to have ant tasks that would make it even easier to run 
> the tests with EMMA.
