How complicated do you expect the rule to be which identifies tests?

If you check, you will see that I kept the "single function that 
generates multiple tests using yield"... the tests themselves don't have 
to be in a class which subclasses off of UnitTest, instead they are 
grafted on later.

Since you asked, my first preference is to avoid dependencies which are 
not in the standard library.  My second preference is to avoid 
dependencies which are not available via apt-get in Ubuntu.  The latter 
brings in json, but does not bring in nose.

The fact that it is Ubuntu isn't important, it merely is an indirect 
measure of how common or standard a given module is.  My experience is 
that the more non-standard and non-common you go, the smaller the 
development community will be, and the more fragile the module itself 
will be.

But if you decide to go for nose, then I would agree, there is no need 
for UnitTest.
