can you create a helper class in views test support called
views::WebViewTestHelper. It'd create/own the ui thread, rph factory, rvh
factory. This test class would then just have one as a member.

+ public:
+  ScreensaverViewTest()
+      : rph_factory_(new content::MockRenderProcessHostFactory()),
+        rvh_factory_(
+            new content::TestRenderViewHostFactory(rph_factory_.get())) {
+    url_ = GURL("http://www.google.com");
+
+    test_content_client_initializer_.reset(new TestContentClientInitializer);
+
+    MessageLoopForUI* ui_loop = message_loop();
+    ui_thread_.reset(
+        new content::TestBrowserThread(content::BrowserThread::UI, ui_loop));
+
+    internal::ScreensaverView::webview_factory_ =
+        base::Bind(ScreensaverViewTest::CreateTestWebView);
+  }
+
