LabVIEW Unit Test parallel test for loop code coverage

When using LabVIEW 2013 Professional with LabVIEW Unit Test Framework Toolkit 2013 on Windows 7 Professional 32-bit, there seems to be an issue with the code coverage metric when using parallel for loops.  In my test, there is an array that is fed into a parallel for loop for processing.  When I run the unit test on the VI, I can't get 100% code coverage because of the for loop.  If I disable parallel execution in my for loop, the unit test framework gives 100% code coverage.  Does anyone know how to allow for parallel for loops while still getting 100% code coverage in the unit test framework?

Hi ductape1,

 

I am checking with our R&D team on this behavior. It may take them a few days to get back to me but I will post here as soon as I have an update.

It brings up a few interesting points to ponder.

 

Can you share how much the metric changes with a parallized loop? (does it resolve to 1 diagram or "P-1" that is uncovered?)

Hi ductape1,

 

I have filed a Corrective Action Request for this issue (CAR# 475037). There currently isn't a timeline for fixing this issue, but you can use the CAR number to check whether this issue has been fixed/

Catherine, thanks for the information!  I'm glad to know it wasn't just me having the problem.

Jeff, 

 

The metric just counts the parallelized for loop as one path, exactly the same as passing n=1, and the metric wants to count the looping of the loop as a path, so n=2 would be sufficient for 100% coverage.
