[TIP] I have some data files I want to use in my tests -- how do I specify where they are?

[Matthew Wilson]

I'm writing some code to extract and yield some attachments out of
email messages.  I have a file named email_parsers.py and another file
in a tests/ subdirectory named test_email_parsers.py

I have a few email messages saved as text files. These files are in
that tests/ directory.

In my test code, I want to know how to open those email files.  Should
I use something like os.dirname(__file__)?

I know I won't always run my tests from the tests/ subdirectory

TIA!

Matt
