| // A MockFunction<F> class has one mock method whose type is F. It is |
| // useful when you just want your test code to emit some messages and |
| // have Google Mock verify the right messages are sent (and perhaps at |
| // the right times). For example, if you are exercising code: |
| // |
| // Foo(1); |
| // Foo(2); |
| // Foo(3); |
| // |
| // and want to verify that Foo(1) and Foo(3) both invoke |
| // mock.Bar("a"), but Foo(2) doesn't invoke anything, you can write: |
| // |
| // TEST(FooTest, InvokesBarCorrectly) { |
| // MyMock mock; |
| // MockFunction<void(string check_point_name)> check; |
| // { |
| // InSequence s; |
| // |
| // EXPECT_CALL(mock, Bar("a")); |
| // EXPECT_CALL(check, Call("1")); |
| // EXPECT_CALL(check, Call("2")); |
| // EXPECT_CALL(mock, Bar("a")); |
| // } |
| // Foo(1); |
| // check.Call("1"); |
| // Foo(2); |
| // check.Call("2"); |
| // Foo(3); |
| // } |
| // |
| // The expectation spec says that the first Bar("a") must happen |
| // before check point "1", the second Bar("a") must happen after check |
| // point "2", and nothing should happen between the two check |
| // points. The explicit check points make it easy to tell which |
| // Bar("a") is called by which call to Foo(). |
| // |
| // MockFunction<F> can also be used to exercise code that accepts |
| // std::function<F> callbacks. To do so, use AsStdFunction() method |
| // to create std::function proxy forwarding to original object's Call. |
| // Example: |
| // |
| // TEST(FooTest, RunsCallbackWithBarArgument) { |
| // MockFunction<int(string)> callback; |
| // EXPECT_CALL(callback, Call("bar")).WillOnce(Return(1)); |
| // Foo(callback.AsStdFunction()); |
| // } |
