Create friendly way for users to test their code #1

When users add a script, it should work within a virtual environment with the requirements given by the user.

This means each folder will have a .py python script and a requirements.txt file.

We have two options:

1. We can have the user create a test file and test via pytest.
   • Pros: The testing with pytest is easy.
   • Cons: The first part may be difficult for the user.
2. We can create a bash script that runs the new script with source run_script [path] from the terminal. This has been implemented in the tests folder and in github actions.
   • Pros: This means the user does not need to provide anything other than the .py and .txt files. For me this is very important.
   • Cons: It is more complicated to implement and because it is a bash script, it doesn't stop if there is a Python error. Could capture and parse the stdout and display a "Fail" message at the end of the script.
