Perhaps the most obvious test in building a new product is to check that the rules return expected eligibility and entitlement results based on the data captured. The most practical way to do this is to see if it is possible to create a product delivery for the new product and perform a manual eligibility check. If the product and its rules are configured correctly, the output of the rules will deem the client either eligible or ineligible. If no rules are associated to the product for a given period, the determination will include a decision of 'Eligibility could not be determined' for that period. If an error occurs, then no determination will be created and logs can be interrogated to see what the underlying problem is.
In addition to checking that the rules return expected eligibility and entitlement results, it is also important to check that the key decision factor and decision display rules return the expected visual results. The manual eligibility check can also be used to check the display output for decision details rules, but an assessment determination created during case activation must be used to check key decision factors.
