It helped me look at my structure afresh, move some files to the upper directory, and get the unittest to progress. In order to find the basicfunction module, we need to change our unit test import statement: After updating …/project2/test/test_basicfunction.py with the updated import statement, you should now be able to run the unit tests: SUCCESS!!! To help illustrate the verbose output, update the unit test file (basicfunction.ut.py) to include a second unit test: Now the output from running the unit tests look like: Not a bad start to our unit testing, but this isn’t a very complex example. Since we don’t have __init__.py in our project2 and test directories, the python interpreter does not recognize this directories as python packages.

To start off with a basic example, we’ll use the following file/directory structure: Here is the source code for basicfunction.py: To start, let’s create a really basic unit test file that doesn’t even care about basicfunction.py yet: The unit test file starts off by importing the built-in ‘unittest’ module from python.
