Introduce unit tests to current codebase
Do you intend to cover both parts (PHP and Python) with unit tests within this task, or is it relevant only for one of them?
I've implemented some tests with basic testing infrastructure, including a short overview document.
@muppeth, please take a look and if you approve (if tests pass on your environment), accept the change.
Deleting a branch is permanent. It CANNOT be undone. Continue?
