Translate unittest to pytest & TDD

[JayDwee]

This will normally not be a separate issue and will instead be expected in all development

Is your feature request related to a problem? Please describe.
The first step to any task should be creating tests for the requirements (Test Driven Development).
Also, the tests will need to be made with pytest rather than unittest.

Describe the solution you'd like

• Create a virtual environment for your development see here
• Your will need to use pip to install pytest
  • Create a requirements.txt for this within the src folder (google what this is if you aren't sure)
• Translate the current unittest test into pytest
• Create at least one pytest test for each requirement found here

You can create a branch and work as a team through one person, or create a team branch which your team branches off, and merges into until complete.
