Fix #28
test file for issue #28

Great work 🎉 , @Yoda-Canada! Just a small issue with the name of each test. I'd rather have something as verbose as test_supported_windows_file_path than test_is_filetype_supported1.

I have changed all names, but there are three commits. I am confused how to merge them to one. Because I feched new commit from your origin rpo, and when I git rebase main -i, I can't find the commit which I need to merge.

Sorry if I didn't make it clear enough, @Yoda-Canada. What I was trying to say is that you should name the test cases according to what it wants to test.
For example:

def test_supported_windows_file_path6():
    file_path = "/Users/anonymous/Documents/test"
    assert is_filetype_supported(file_path) == False, "empty extension error"

test_supported_windows_file_path6 doesn't explain what the test does. The test actually checks a Unix file path ("/Users/anonymous/Documents/test") that has no extension. Therefore, it'd better to name it test_empty_extension_unix_file_path. I think it's good practice to name each test case descriptively so that it should give developers a clue about what the test case does.

Don't worry about rebasing for now. I can help you with that from my end.
