Subject: RE: [Cobertura-devel] All my packages have zero coverage
A few things:
* You can do a search on your computer for files named "cobertura.ser"
This file is created when you instrument your classes, and it's SUPPOSED
to be updated by your classes when your tests are run. However,
depending on which directory your tests are run from, your classes may
instead just create a second cobertura.ser file. If you have 2 of these
files in different directories, then this is likely the root of your
"0%" coverage.
* I'm not sure I quite trust the "merge" task... That code is largely
unchanged from the jcoverage days, and other parts of Cobertura have had
fairly major changes. It is in need of a good overhaul.
And looking at your output, it DOES look like you have multiple ser
files: "[junit] - java.io.FileNotFoundException:
C:\ClearCase\mcinnesa_credit-dev\fo_CDT_Credit\CDT\Server\build\cobertur
a.ser (The system cannot find the file specified)"
For now I think the best thing to do is to move your cobertura.ser
before and after you run your tests. You'll want to move the file to
wherever your test classes expect to find this file. Yes, I know this
is a bit ugly. Hopefully this will all be much easier to deal with in
Cobertura 1.3 (mostly due to clearer documentation).
