I lifted this helper macro out of SourceBufferStreamTests, since it's useful now
in other places.

+  EXPECT_CALL(*media_log_, DoAddEventLogString((x)))
+
 namespace media {
 
 class MockMediaLog : public MediaLog {
  public:
   MockMediaLog();
 
   MOCK_METHOD1(DoAddEventLogString, void(const std::string& event));
 
   // Trampoline method to workaround GMOCK problems with scoped_ptr<>.
   // Also simplifies tests to be able to string match on the log string
   // representation on the added event.
   void AddEvent(scoped_ptr<MediaLogEvent> event) override {
     DoAddEventLogString(MediaEventToLogString(*event));
   }
 
  protected:
   virtual ~MockMediaLog();
 
  private:
   DISALLOW_COPY_AND_ASSIGN(MockMediaLog);
 };
 
 }  // namespace media
 
 #endif  // MEDIA_BASE_MOCK_MEDIA_LOG_H_
