Hello! I am testing a rather complex system, which behaves according to some business rules (written as semi-formal text). The goal is to create test cases, which cover as many states of the system as possible. I want to automate this task in the following way: 1) Formalize the business rules in Drools 2) Then use some mechanism to create a list of all possible situations (which need to be tested) For example, I have following business rule package with two rules (this is only an example, real business rules are much more complex): global List outErrorCodes; global Boolean condition1; global Boolean condition2; global Boolean condition3; rule "01" when eval( condition3 == false); then outErrorCodes.add("ERROR_CODE1"); end rule "02" when eval((condition1 == true) && (condition2 == true)); then outErrorCodes.add("ERROR_CODE2"); end condition1, condition2 and condition3 are inputs. outErrorCode is the output. That is, condition1, condition2 and condition3 describe a certain situation, and outErrorCode describes the expected behaviour of the system in that particular situation. I want to create a mechanism, which automatically creates a list of all possible tuples (condition1, condition2, condition3, outErrorCodes), based on the logic in the rules. Each tuple represents a state of the system. These tuples will then be used as a basis for creating actual test cases. Is it possible with Drools? If so - how?
