Verifying and Test Spies
Verifying Mockolates
For all strict Mockolates an easy call to verify(instance) will check that all the mock(instance) expectations have been called their expected number of times (at least once, unless changed).
import mockolate.verify;
[Test]
public function verifyThusly():void
{
var flavour:Flavour = strict(Flavour);
mock(flavour).property("name").returns("");
// use our mockolate
var name:String = flavour.name;
verify(flavour);
}
It’s a good thing we called flavour.name else we would have got a mockolate.errors.ExpectationError.
Spying on Mockolates
Using Test Spies in Mockolate is a combination of assertions and the Mockolate stubbing interface. To determine what methods, getters, and setters were called on a Mockolate instance use assertThat() and the received() Matcher.
[Test]
public function iSpyWithMyLittleEye():void
{
var flavour:Flavour = nice(Flavour);
var otherFlavour:Flavour = nice(Flavour);
// ... do some work with the instances.
// check that flavour.name was called at all.
assertThat(flavour, received().method('name'));
// check that flavour.combine() was called with any args
assertThat(flavour, received().method('combine').args(anything()));
// check that flavour.combine() was called with a specific instance of flavour
assertThat(flavour, received().method('combine').args(strictlyEqualTo(otherFlavour)));
// check that flavour.combine() was called with a number of flavours, any instance.
assertThat(flavour, received().method('combine').args(instanceOf(DarkChocolate), instanceOf(Flavour)));
// check that flavour.combine() was called at least 3 times
assertThat(flavour, received().method('combine').atLeast(3));
// check that flavour.combine() was never called
assertThat(flavour, received().method('combine').args(Curry, IceCream).never());
}
