Tests separate from your code

An alternative to the method above is to organize your tests in a separate directory from the main package:

setup.pymylib/      __init__.py    core.py    utils.pytests/    __init__.py    test_core.py    test_utils.py 

Some people prefer this layout because:

• It keeps library code and testing code separate
• The testing code is not included in the source package

One disadvantage of the above method is that, once you have a more complex hierarchy, you will probably want to keep the same hierarchy inside your tests directory, and that's a little harder to maintain and keep in sync:

mylib/      __init__.py    core/        __init__.py        foundation.py    contrib/        __init__.py        text_plugin.pytests/    __init__.py    core/        __init__.py        test_foundation.py contrib/ ...
