Create unit tests for main.py

[mitchelbaker-cisa]

Prerequisites

• This issue has an informative and human-readable title.

💡 Summary

Create a new function, test_main.py, which will house the unit tests for the main.py function.

The test_main.py function should be stored inside of the scubagoggles/Testing/Python directory.

scubagoggles

• Testing
  • Functional
  • Rego
  • Python
    • test_main.py

Motivation and context

This issue is in relation to epic #330

Implementation notes

We will use the pytest library for implementing unit tests and use a class-based approach for the file structure.

For the test_dive* methods, use the unittest library's built-in mocker functionality to mock each scubagoggles subcommand, e.g. gws, setup, etc.

class TestMain

• test_get_gws_args_adds_expected_arguments(self, ...)
• test_get_opa_args_adds_expected_arguments(self, ...)
• test_get_setup_args_adds_expected_arguments(self, ...)
• test_get_purge_args_adds_expected_arguments(self, ...)
• test_get_version_args_adds_expected_arguments(self, ...)
• test_log_level_normalizes_abbreviations(self, ...)
• test_log_level_raises_error_on_invalid_input(self, ...)
• test_dive_dispatches_to_gws(self, ...)
• test_dive_dispatches_to_getopa(self, ...)
• test_dive_dispatches_to_purge(self, ...)
• test_dive_dispatches_to_setup(self, ...)
• test_dive_dispatches_to_version(self, ...)

Acceptance criteria

• The test_main.py function is added
• TestMain class is implemented with methods that test the required behavior for each function declared in main.py
