-// PageTimingSender implementation for use in tests. Allows for setting and
-// verifying basic expectations when sending PageLoadTiming. By default,
-// FakePageTimingSender will verify that expected and actual
-// PageLoadTimings match on each invocation to ExpectPageLoadTiming() and
-// SendTiming(), as well as in the destructor. Tests can force additional
-// validations by calling VerifyExpectedTimings.
-//
-// Expected PageLoadTimings are specified via ExpectPageLoadTiming, and actual
-// PageLoadTimings are dispatched through SendTiming(). When SendTiming() is
-// called, we verify that the actual PageLoadTimings dipatched through
-// SendTiming() match the expected PageLoadTimings provided via
-// ExpectPageLoadTiming.
-//
-// Normally, gmock would be used in place of this class, but gmock is not
-// compatible with structures that use aligned memory, and PageLoadTiming uses
-// base::Optional which uses aligned memory, so we're forced to roll
-// our own implementation here. See
-// https://groups.google.com/forum/#!topic/googletestframework/W-Hud3j_c6I for
-// more details.
