unit--, the unit test aid for C++

Hi,

Thanks for your post, here is my consideration:

1, test cases are registered and run with an undefined order. for those general/outer layers, personally, i prefer to provide some mock objects that emulate the needed inner objects.

it's just unit test, rather than integrated test -- any layers should be tested independently. when i find it impossible, i know it might be the time to improve the design

2, it is a feature to be added
but i'm still considering what is an advisable interface

it might have the mechanism to:
* filter unneeded(e.g. time consuming) units
