Unit test fails on MAC

[Regina Henschel]

Hi all,

My new unit test fails on Mac. But I can't see what's going wrong. The 
output does not contain any "expected - actual" pair. The test is OK on 
the other operating systems. I have no Mac to test it myself. Can 
someone help me?

Kind regards,
Regina
