Hi @contributor, thanks for the PR. The feature shape looks reasonable. I have a few things I'd like to discuss before approving.

The retrieveCalculationTypes override returns null when chargeAppliesTo is WORKING_CAPITAL_LOAN and chargeTimeType is provided but isn't SPECIFIED_DUE_DATE - that's a potential NPE for any caller that iterates the returned list. And in the step defs, the new methods break the pattern established by the rest of the file and hardcode raw integers where the existing code uses proper enum types.

Also one small thing in the feature file. Thoughts?
