Daniel John Debrunner commented on DERBY-3445:
----------------------------------------------

Thanks Vemund, I was able to get code coverage running very easily now using 
the emma-all target.

With the previous EMMA reports I was able to click down through the HTML report 
to an individual file and see which specific blocks had not been covered, I 
think with coloured source code. With the report I just generated using 
emma-all I was not able to see this information. The lowest level was the 
coverage breakdown by method.

Anyone any idea what needs to be done to get the source code level information?

> 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.
