issues encountered

test cannot find module

• Solution#1 on StackOverflow
• info from docs.pytest.org

This is something to do with the way pytest handles the root of the project. It seems to be caused when all the python source files are held within sub folders in the project folder. Looking at the stackoverflow responses in solution #1 there are two solutions:

1. instead of using pytest -sv use python3 -m pytest -sv
2. add an empty python file to the root of your project structure.

The info from docs.pytest.org seems to favour option 1.
