Google Guava Predicates.or() or Predicates.and() type

In Guava, there is a utilities kind of method for Predicates class called 'or' or 'and', you can either pass a iterable or two predicates.

I have a code example like below:

class AccountNamePredicate implements Predicate<Account> {}
class AccountTypePredicate implements Predicate<Account> {}
class AccountManager {
    public Predicate<Account> getPredicate() {
         return Predicates.and(new AccountNamePredicate(), new AccountTypePredicate());
    }
}

My question is for the method getPredicate in AccountManager class, how can I test the method?

If I want to assert the return type of this method, how can I write the correct code. My assert statement below doesn't pass:

assertThat(getPredicate(), is(instanceOf(Predicate.class)));

Any idea about that?

There is nothing to test in your scenario. If you insist on test that you're testing the guava framework (guava development team already do that well) not your application.
