How to verify that a method was NOT called?

[Kristopher Schultz]

What is the most appropriate way to write a test that verifies that a particular method was NOT called? For example, I want to implement a test described as "When Widget.methodA() is called it should not trigger Widget.methodB()".

[Hob Spillane]

how about:

expect(mock.methodB()).times(0)

Thanks, Hob. That works. So does...

expect(mock.methodB()).never()

The "teach a man to fish" answer turned out to be referencing the API docs for mockolate.ingredients.MockingCouverture which defines all sorts of useful constraint methods.

An alternative (if you build from master) is to use a Test Spy like so: 

    var spy:Spy = spy(mock.methodB());

    // do rest of test

    assertFalse(spy.called());

Using a test spy in this case may be overkill, but if you need more granular access to the invocations it can be useful.

Can't you do expect(a.b()).never()?
