Often our code uses pytest and Lee's version wield.pytest. If given a file with these tests and they don't run, add the attached files to the folder. They tell pytest what to do and how it handle it correctly.
to make a test make a function with a name that states with "T_". Then run the command:
or replace the period with the file name and it will run all the tests in that file. Us the code in post about the GQuEST Spectrum models to see an example.
