[TIP] Can pytest identify python code that has no test

[Ned Batchelder]

Coverage will only find files that it considers importable.  It's 
essential that you have __init__.py files in the subdirectories. Those 
files can be empty, no one needs to update them.

Your original output showed a __init__.py file, but this latest run does 
not.
