[rules-users] drools-guvnor, problem when creating test scenarios based on referenced domain model

Hi all, first of all, i appologise if i'm starting a topic that already exists (but i couldn't find one :-) i'm having some difficulties with creating test scenarios in guvnor when the domain model is based on referenced objects. Suppose we have a model like this one: Class Role with attributes: roleId: Long roleName: String Class User with attributes: userId: Long userName: String firstName: String lastName: String role: Role Then, lets suppose the rule like this one (it's pritty simple one) rule "my first rule" dialect "mvel" when usr: User(firstName=="John", lastName="Doe", role.roleName="ADMIN" ) then usr.userName="ADMIN" end Now, i'm trying to create a test scenario for this rule. And my nightmare begins... Seems to me that there is no possibility to define referenced object in test scenario, ie: GIVEN User [usr] firstName = "..." lastName = "..." *role.roleName = "..."* EXPECTING .............. Hope that you can understand what i'm talking about. Can somebody (pretty please) give me some directions how to achieve something like this in test scenarios. Thank you for your answers and suggestions (if any) :-))
