GoogleMock: Expect either of two method calls

Question

I have a class Foo that references multiple other objects of type IBar. The class has a method fun that needs to invoke method f

Answer 1

This can be achieved using check points:

using ::testing::MockFunction;

MockFunction<void()> check_point;
EXPECT_CALL(*bar1, frob())
    .Times(AtMost(1))
    .WillRepeatedly(
        InvokeWithoutArgs(&check_point, &MockFunction<void()>::Call);
EXPECT_CALL(*bar2, frob())
    .Times(AtMost(1))
    .WillRepeatedly(
        InvokeWithoutArgs(&check_point, &MockFunction<void()>::Call);
EXPECT_CALL(check_point, Call())
    .Times(Exactly(1));
