Test

[leotrs]

Before working on another PR, I wanted to implement some basic tests.

• test/test.py implements one test for each module, plus one for the readme.mdpp file, using the unittest package.
• test/test_include.py is a dummy file used in tests.
• The change in Modules/IncludeURL.py was necessary in order to make the !INCLUDEURL directive accept uris of the form file://path_to_local_file (used in test.test_include_url). Of course, including local files is not the point of IncludeURL, but it seemed like a small enough change to make the test work. Furthermore, I couldn't think of a good static url that would always reliably return the same text, so I settled for including a local file.

Could you add this to makefile so that running make test will run these unit tests and fail if they fail?

Looks like you need to add the from __future__ imports to the test cases.

Using this import in test.py passes all tests:

try:
    from StringIO import StringIO
except ImportError:
    from io import StringIO

It's not pretty, but given that StringIO is only being used in the test suite, it makes sense to branch an import based on python version.

Thank you!
