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

New in 0.7 (2)

def person = Stub(Person)

def person = Spy(Person, constructorArgs: ["Fred", 30])

def person = GroovyMock(person) // GroovyStub, GroovySpy

def person = Mock(Person) {    1 * sleep()    sing() >> “tra-la-la”}
