 218 //   Foo(1);

 220 //   Foo(3);
 221 //
 222 // and want to verify that Foo(1) and Foo(3) both invoke

 239 //   check.Call("2");

 243 // The expectation spec says that the first Bar("a") must happen
 244 // before check point "1", the second Bar("a") must happen after check
 245 // point "2", and nothing should happen between the two check
 246 // points. The explicit check points make it easy to tell which
 247 // Bar("a") is called by which call to Foo().
 248 //
 249 // MockFunction<F> can also be used to exercise code that accepts
 250 // std::function<F> callbacks. To do so, use AsStdFunction() method
 251 // to create std::function proxy forwarding to original object's Call.

 253 //
 254 // TEST(FooTest, RunsCallbackWithBarArgument) {
 255 //   MockFunction<int(string)> callback;
 256 //   EXPECT_CALL(callback, Call("bar")).WillOnce(Return(1));
