profile.run() doesn't have access to the setUp() method's local namespace,
it looks into the global (module) namespace.
A stripped-down example:
>>> import profile
>>> def demo():
... def foo(): print "local"
... profile.run("foo()")
...
>>> demo()
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "<stdin>", line 3, in demo
File "/usr/lib/python2.6/profile.py", line 70, in run
prof = prof.run(statement)
File "/usr/lib/python2.6/profile.py", line 456, in run
return self.runctx(cmd, dict, dict)
File "/usr/lib/python2.6/profile.py", line 462, in runctx
exec cmd in globals, locals
File "<string>", line 1, in <module>
NameError: name 'foo' is not defined
>>> def foo():
... print "global"
...
>>> demo()
