@Kasper: I need your help here. I can't reproduce your problem.
Here's what I've tried. Source code:

It all seems to work to me. The `ModuleATest.mix` file is indeed generated
twice, but it doesn't seem to bother `hpc sum`.
You mention "When performing hpc sum and hpc markup to get the total
result of the test runs I need to specify the directories where the mix
files are present". What is the command you use to run `hpc sum`. My
understanding is that `hpc sum` only takes .tix files, not .mix files.
I must be missing something, so please clarify.
