Do you need to update any gyp dependencies?

[Yuki, 2014/06/20 01:30:50]

Yes, you're right.  I've added a dependency to ui_base.

   aura::Env::CreateInstance(true);
   aura::Env::GetInstance()->set_context_factory(context_factory);
   host_.reset(aura::WindowTreeHost::Create(gfx::Rect(default_window_size)));
   host_->InitHost();
   aura::client::SetWindowTreeClient(host_->window(), this);
 
   focus_client_.reset(new aura::test::TestFocusClient);
   aura::client::SetFocusClient(host_->window(), focus_client_.get());
 
   root_window_event_filter_.reset(new wm::CompoundEventFilter);
   host_->window()->AddPreTargetHandler(root_window_event_filter_.get());
 
   input_method_filter_.reset(new wm::InputMethodEventFilter(
       host_->GetAcceleratedWidget()));
   input_method_filter_->SetInputMethodPropertyInRootWindow(host_->window());
   root_window_event_filter_->AddHandler(input_method_filter_.get());
 
   new wm::DefaultActivationClient(host_->window());
 
   capture_client_.reset(
       new aura::client::DefaultCaptureClient(host_->window()));
 }
 
 WMTestHelper::~WMTestHelper() {
   root_window_event_filter_->RemoveHandler(input_method_filter_.get());
+  ui::TextInputFocusManager::GetInstance()->FocusTextInputClient(NULL);
 }
 
 aura::Window* WMTestHelper::GetDefaultParent(aura::Window* context,
                                              aura::Window* window,
                                              const gfx::Rect& bounds) {
   return host_->window();
 }
