Configuring Package File Structure

Step 1: Another solution is to configure the package file structure to include a __init__.py file in each subpackage.
Step 2: This will allow nose to recognize modules beneath the test script and import them correctly.
Step 3: For example, adding an empty __init__.py file to the tests directory would enable nose to look for tests in that directory.
