This checklist is used to make sure that common guidelines for a pull request are followed.

General Guidelines

• If introducing new functionality or modified behavior, are they backed by unit and integration tests?
• In the same context as above are command names and their parameter definitions accurate? Do help docs have sufficient content?
• Have all unit and integration tests passed locally? i.e. pytest <project root> -vv
• Have static checks passed using the .pylintrc and .flake8 rules? Look at the CI scripts for example usage.
