I need to add tests but I'm really not sure how to approach it (What to mock mainly).

I think adding the following additional tests for the is_static method should be sufficient?

• Test a path isn't identified as a staticfile when a staticfile directory has the same name
• Test a path is identified as a staticfile, when it's parent directory is in the staticfiles parameter
• Test a path is identified as a staticfile, when the relative path is specified in the staticfiles parameter

Hey @alex-way, thanks for submitting this. Indeed that does look like it's broken. I will note that according to the docs using staticpaths is officially deprecated, although so many people use it that it's basically a feature. I'll try to get to this issue soon. I'm not sure if I want to keep supporting staticpaths or not at this point. We do need test cases if so. Thanks for your patience!
