Regression Rule Testing

On top of the mandatory ad-hoc verification of the factual correctness of the given rules using real data sample simulation, ERIAN also offers the option to create specific test scenarios for individual rules which are made of input data definitions and the expected decision results – results expected for the given input data. These scenarios are stored together with the rules and allow quick and efficient verification of the correct functionality of one or several rules, for example, under the release management process when a new version of rules is released or when the impact of changes of surrounding systems needs to be verified.
