This lesson describes how you can configure stubs to match on user-defined objects, as opposed to those classes built into Java.
Mockito has built-in matchers for the likes of
anyBoolean() and so on, but what happens when you need to match on a class you wrote yourself?
We describe the use of the
any() matcher which matches on any types and any values, including nulls.
Additionally, we describe the use of the overloaded
any(Foo.class) matcher, which requires an instance of the user-defined class Foo to match; this will not match on nulls.
