Sorry for the confusion. Can you rename this class to ContextMenuWaiter and make
it inherit content::NotificationObserver?

 class SaveLinkAsContextMenuObserver : public ContextMenuNotificationObserver {
  public:
   // Register to listen for notifications of
   // NOTIFICATION_RENDER_VIEW_CONTEXT_MENU_SHOWN from either
   // a specific source, or from all sources if |source| is
   // NotificationService::AllSources().
   explicit SaveLinkAsContextMenuObserver(
       const content::NotificationSource& source);
   ~SaveLinkAsContextMenuObserver() override;
 
-  // Suggested filename for file downloaded through "Save Link As" option.
-  base::string16 GetSuggestedFilename();
+  content::ContextMenuParams& params();
 
-  // Wait for context menu to be visible.
-  void WaitForMenu();
+  // Wait until opening the context menu and closing.
+  void WaitForMenuOpenAndClose();
 
  private:
   void Observe(int type,
                const content::NotificationSource& source,
                const content::NotificationDetails& details) override;
 
   void Cancel(RenderViewContextMenu* context_menu);
 
   bool menu_visible_;
   content::ContextMenuParams params_;
 
   DISALLOW_COPY_AND_ASSIGN(SaveLinkAsContextMenuObserver);
 };
