In PR #2669 we have added that's test specific code, we should avoid writing such code. We have done this in a few places and i think its a bad habit, I believe we should take the time to re-structure the code where necessary.

Its an indication that code needs to be refactored for testability.

Solution:

• Create a method initialize
• Move the code thats inside the if condition in the constructor into the initialize method
• For testing purposes, create a subclass of the PythonSettings class, override the initialize method.
