Perhaps we should create a common base class for WMTestHelper and Android's
WindowTreeHostManager?

  public:
-  WMTestHelper(const gfx::Size& default_window_size,
-               ui::ContextFactory* context_factory);
-  ~WMTestHelper() override;
+  WindowTreeHostManager(const gfx::Size& default_window_size,
+                        ui::ContextFactory* context_factory);
+  ~WindowTreeHostManager() override;
 
   aura::WindowTreeHost* host() { return host_.get(); }
 
   // Overridden from client::WindowTreeClient:
   aura::Window* GetDefaultParent(aura::Window* context,
                                  aura::Window* window,
                                  const gfx::Rect& bounds) override;
 
  private:
   scoped_ptr<aura::WindowTreeHost> host_;
 
   scoped_ptr<wm::CompoundEventFilter> root_window_event_filter_;
   scoped_ptr<aura::client::DefaultCaptureClient> capture_client_;
   scoped_ptr<aura::client::FocusClient> focus_client_;
