// 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());
// }

// 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());
