206//
207// Foo(1);

209// Foo(3);
210//
211// and want to verify that Foo(1) and Foo(3) both invoke
212// mock.Bar("a"), but Foo(2) doesn't invoke anything, you can write:
213//
214// TEST(FooTest, InvokesBarCorrectly) {
215// MyMock mock;

234// point "2", and nothing should happen between the two check
235// points. The explicit check points make it easy to tell which
