[Chicago] Using globals across files

[Chris Cope]

I'd like to set global varibles and use them across files, but can't 
find out how to do this (if it's possible). I'm using it for keeping 
track of unit tests, and believe a global is the right solution, rather 
than something like passing testsPassed and testsRun to Test(). Google 
doesnt return a solution, just other people with the same problem. Any 
ideas?

I get the error "NameError: global name 'testsPassed' is not defined" 
when trying to increment it in tests.py. The code follows.

Thanks,
Chris

# File tests.py
import inspect

def Test(cond):
     global testsPassed
     global testsRun
     if cond:
         testsPassed += 1
     testsRun += 1



# File MyTests.py

global testsRun
global testsPassed
testsRun = 0
testsPassed = 0

import tests

def runTest1():
     x = 0
     y = 0
     tests.Test(x == y)

runTest1()
print "Summary:", testsPassed, "of", testsRun, "test(s) passed."
