i dislike gmock (i think that its code is hard to read, and that it spams logs,
and that it often encourages testing of minutia of behavior that we don't
actually care about).  that said, the use here seems legitimate (you're testing
whether the fullscreen parameter is true or not).

beng@ points out that there's no use of gmock in ash currently and suggests that
he'd like to keep things that way.  would you object to tracking the number of
fullscreen/non-fullscreen calls in the existing mock class instead of adding a
gmock implementation?

Since the preference is to not use it I am fine with changing this.

+ public:
+  MOCK_METHOD1(OnVideoDetected,
+      void(bool is_fullscreen));
+  void ExpectOnVideoDetected(bool is_fullscreen) {
+    EXPECT_CALL(*this, OnVideoDetected(is_fullscreen))
+                .Times(1)
+                .RetiresOnSaturation();
+  }
+};  // class MockVideoDetectorObserver
+
+}  // namespace ash
+
+#endif  // ASH_WM_MOCK_VIDEO_DETECTOR_OBSERVER_H_
