No, I agree woth that, `testDir` is a bad name.

However I didn't go with `dir` because it's a built-in python function:
```
Python 2.7.2 (default, Jun 16 2012, 12:38:40) 
[GCC 4.2.1 Compatible Apple Clang 4.0 (tags/Apple/clang-418.0.60)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> dir
<built-in function dir>
>>> dir()
['__builtins__', '__doc__', '__name__', '__package__']
>>> 
```

How about `repoDir` as a name?
