#11 Run Summary shows suites-failed: 0

[Anonymous]

The run summary shows the following output:

--Run Summary: Type Total Ran Passed Failed
suites 1 1 n/a 0
tests 2 2 0 2
asserts 4 4 2 2
ModuleTest completed with return value 0.

How can suites/failed be 0 here?
Why is the return value of CU_basic_run_tests() == 0, although errors occured.

Thanks for your help.
