Is it possible for an assembly to run with Attributes which reference
unresolved assemblies?

I would think that the mere appearance of [MyTest] would mean that plugin
assembly would have to be present to run the code. 


I see what you're saying. If [MyTest] compiled, the addin must have been
available. However...
 
1. Tests are sometimes compiled in one place, then execcuted elsewhere.
2. Having an assembly available to be referenced does not necessarily mean
that it's
properly installed as an addin - although NUnit /could/ try to find and use
it in that case.
3. Most important, the canonical implementation of an addin does /not/ put
the definition
of any special attributes in the same assembly as the addin itself because
of reference
problems that arise. This could change in 3.0, but is still the recommended
pattern
for 2.5.
 
So, for all those reasons, it is indeed possible ot have an attribute for
which the
addin is not available. In the case of [MyTest], the test will simply not be
seen and
whether anyone notices is an open question.
