Creating
Mocking
Recap: Interaction Based Testing
def sub = Mock(Subscriber)Subscriber sub = Mock()
1 * sub.receive("msg")(1..3) * sub.receive(_)(1.._) * sub.receive(_ as String)1 * sub.receive(!null)1 * sub.receive({it.contains("m")})1 * _./rec.*/("msg")
Stubbing
Mocking and Stubbing
Impressing your friends
Recap: Interaction Based Testing (2)
// now returns status codeString receive(String msg) { ... } sub.receive(_) >> "ok"sub.receive(_) >>> ["ok", "ok", "fail"]sub.receive(_) >> { msg -> msg.size() > 3 ? "ok" : "fail" }
3 * sub.receive(_) >>> ["ok", "ok", "fail"]
(_.._) * _._(*_) >> _
NEW IN 0.7What’s new?
Group conditions/interactions w/ same target
Better mocking failure messages
New in 0.7 (1)
with(person) { name == “Fred” age == 30 sex == “male”} with(service) { 1 * start() 1 * stop()}
Stubs
Spies
Groovy mocks
Declare interactions upfront
