Add better test functions #128
Description
Feature
Desired Behavior / Functionality
Current test functions are based only on polynomials and sinusoidal and exponential functions.
What Needs to Be Done
- Find nice test functions (e.g. in VEGAS Enhanced paper )
- Add them to integration_test_functions.py
- Add them in integration_test_utils.py so they become part of the standard test sweet
- If necessary adjust current tests in case they fail
How Can It Be Tested
- Run pytest
