; NMock will only verify the value of a parameter, not the actual refe=
rence. In your test, you assign the variable 'refStringArr' to null, =
then pass it to your mock. This will fail (assuming the bug has been =
fixed) because NMock is expecting the original value assigned to strArr, wh=
ich was {"a", "b"}. Even if NMock could have compared the reference r=
efStringArr with strArr, however, it still would have failed, because they =
are different references. So I'm not sure what you expect the behavio=
r to be.</DIV><DIV> </DIV><DIV>Anyway, I have fixed the bug, and it sh=
ould make its way onto SourceForge in the next day or so.</DIV><DIV> <=
