Business Oriented Testing: FIT vs. DSL
Jeremy Miller is talking about getting disillusioned about FIT, and I have to agree. FIT is a good idea, but the implementation leaves a lot to be desired. For myself, I am very interested in the ability to express the requirements in a way that is clear, concise and can hopefully make sense to a business user.
Instead of going with the FIT route, I think that I would go with a DSL for testing the domain. For instance, let us say that I want to test scheduling work for employees.
Something like this:
emp = Employee("Smith", Qualifications: [ Medic, Doctor ] ) requirement = Requirement(For: Medic) assert requirement.MatchedBy(emp)
Now, this looks a lot a unit test, right, but the advantage here is with the bigger scenarios, this mainly simplify ObjectMother scenarios, but it can make the test a lot easier to figure out.
doc = Employee("Smith", Qualifcations: [Medic, Doctor] ) driver = Employee("Joe", Qualifications: [Driver, Medic] ) cannot_work_together doc, driver, "Had a fight" shift = Shift("Morning") task = shift.Tasks.Add("Ambulance") task.AddRequirement( Requirements.Doctor ) task.AddRequirement( Requirements.Driver ) shift.Add( doc ) assert_would_fail shift.Add( driver ) assert_false shift.CanBeSatisfiedBy( driver )
