[Zope3-dev] strange assertion error

[Arthur (ccube)]

I'm developing a product with three Classes.

The first two run well and passed the unittest. However, the third one 
is the same as the other 2 classes except I changed a Byte field to a 
TextLine. However, this field is not included in the tests at all.

I cannot pass the test for the new Class and have AssertionError. I 
found a msg said that we should not run the test as root:

Is it true we shouldn't run tests as root? if so, why?

Thanks
Arthur
