Testing is OS-Specific (Windows)

[doerrie]

Description

The ability to run any tests is OS-Specific (Windows)

Steps to reproduce

run python setup.py nosetests on Linux

Expected Behavior

More than one test should execute.

Actual Behavior

A TypeError is raised at tests/tools.py:423 for indexing into None.

Environment

• Operating System: Ubuntu 20.04
• Python version (output of python -V): 3.8.5
• fixedpoint version: commit 0707499 (current master)

1-line Repair:

tests/tools.py:423

        directory = re.search(r'^(.+)\\__init__\.py', frame.filename)[1]

should read:

        directory = os.path.dirname(frame.filename)

This allowed me to execute tests.

If the TypeError being raised for indexing into None was being used to implicitly filter for __init__.py then alter to the following:

        if os.path.basename(frame.filename) != "__init__.py":
                raise TypeError
        directory = os.path.dirname(frame.filename)

I have not tested this code, but it is more likely to be backward compatible.

This seems like a pretty straightforward and minor change, would you care to be the first to make a pull request from a fork with those changes?
