-// This class defines tests that implementations of InvalidationFrontend should
-// pass in order to be conformant.  Here's how you use it to test your
-// implementation.
-//
-// Say your class is called MyInvalidationFrontend.  Then you need to define a
-// class called MyInvalidationFrontendTestDelegate in
-// my_invalidation_frontend_unittest.cc like this:
-//
-//   class MyInvalidationFrontendTestDelegate {
-//    public:
-//     MyInvalidationFrontendTestDelegate() ...
-//
-//     ~MyInvalidationFrontendTestDelegate() {
-//       // DestroyInvalidator() may not be explicitly called by tests.
-//       DestroyInvalidator();
-//     }
-//
-//     // Create the InvalidationFrontend implementation with the given params.
-//     void CreateInvalidationFrontend() {
-//       ...
-//     }
-//
-//     // Should return the InvalidationFrontend implementation.  Only called
-//     // after CreateInvalidator and before DestroyInvalidator.
-//     MyInvalidationFrontend* GetInvalidationFrontend() {
-//       ...
-//     }
-//
-//     // Destroy the InvalidationFrontend implementation.
-//     void DestroyInvalidationFrontend() {
-//       ...
-//     }
-//
-//     // The Trigger* functions below should block until the effects of
-//     // the call are visible on the current thread.
-//
-//     // Should cause OnInvalidatorStateChange() to be called on all
-//     // observers of the InvalidationFrontend implementation with the given
-//     // parameters.
-//     void TriggerOnInvalidatorStateChange(InvalidatorState state) {
-//       ...
-//     }
-//
-//     // Should cause OnIncomingInvalidation() to be called on all
-//     // observers of the InvalidationFrontend implementation with the given
-//     // parameters.
-//     void TriggerOnIncomingInvalidation(
-//         const ObjectIdInvalidationMap& invalidation_map) {
-//       ...
-//     }
-//   };
-//
-// The InvalidationFrontendTest test harness will have a member variable of
-// this delegate type and will call its functions in the various
-// tests.
-//
-// Then you simply #include this file as well as gtest.h and add the
-// following statement to my_sync_notifier_unittest.cc:
-//
-//   INSTANTIATE_TYPED_TEST_CASE_P(
-//       MyInvalidationFrontend,
-//       InvalidationFrontendTest,
-//       MyInvalidatorTestDelegate);
-//
-// Easy!
