I tested the PR, and it works fine for me locally, but seems that CI doesn't show a failure when the tests are failing:

!!!!!!!!!!!!!!!!!!! Interrupted: 22 errors during collection !!!!!!!!!!!!!!!!!!!
============================== 22 errors in 0.59s ==============================

The errors reflect that there are many test files with the same base name so might be a reason for that failure. Can you test the same @czgdp1807 if you could produce this error locally?
