I will note that the granularity of the unittests is based on how many 
*modules* were tested. There is only one unittest function in each 
ModuleInfo (as provided by the compiler to the runtime), so that's the 
number that's being reported. So in this case, it's not missing 
unittests, it's running all given unit tests.
