The way that nosetests imports packages in order to navigate to find
test files is a bit wonky. It doesn't respect proper package
semantics. Or perhaps just the behavior that we see from normal
imports. In particular, many of our __init__.py files do something
from foo import **
__all__ = 
The reason why this normally works is that once you do any kind of
import from the foo submodule, it gets added to the namespace of the
package's actual module object. However, nosetests is manually
"importing" the __init__.py file and bypassing the normal import
mechanism, so it misses some of these semantics.
I suspect nosetests may be doing something different to load files
that have been installed into site-packages rather than other
locations. Unfortunately, I don't know a workaround other than to
modify all of our __init__.py file to do more explicit imports rather
than relying on the implicit behavior of the full Python import
