What you're seeing is the affect of the current working directory being 
different when tests are run versus when the main debug file is run.  By 
default, the initial current working directory is the directory that the 
file run in in -- this applies to either the main debug file or the 
individual test files.

There's a couple of workarounds (at least):
  * Set an environment variable and use that when setting your project 
directory
  * Set the project wide initial directory to a custom value.

These do require a change to the project settings for each branch.  We 
do plan to make it possible to eliminate this step in the future.

Cheers,
