Writing Layout Tests for DumpRenderTree

 To test a bug having to do with the loader or the back/forward cache, call this method to run a script after executing a back/forward navigation. The first argument is the script to run, and the second argument is the page to load during the navigation. The second argument is optional. It defaults to `about:blank`.
 
+== `window.internals` ==
+
+=== `createShadowContentElement(Document)` ===
+
+Creates a `<content>` element for use in shadow DOM. These elements can not be created from JavaScript, hence this constructor in the test harness.
+
+=== `elementRenderTreeAsText(Element)` ===
+
+Gets and returns the element’s renderer’s description of its tree as a String.
+
+=== `ensureShadowRoot(Element)` ===
+
+Given a host element, returns its shadow root node. If the element doesn’t have a shadow root one is created and attached to the element. If you want to just retrieve a shadow root without creating one, use ''shadowRoot''. ''ensureShadowRoot'' only inspects DOM shadows; not SVG shadows.
+
+=== `isPreloaded(Document, String url)` ===
+
+Gets whether the specified document’s cached resource loader has the specified URL preloaded.
+
+=== `removeShadowRoot(Element)` ===
+
+Given a host element, removes its shadow root if it has one. ''removeShadowRoot'' only inspects DOM shadows; not SVG shadows.
+
+=== `shadowPseudoId(Element)` ===
+
+Gets the specified element’s CSS pseudo-id for styling when in shadow DOM.
+
+=== `shadowRoot(Element)` ===
+
+Given a host element gets its shadow root, if it has one; otherwise ''shadowRoot'' returns `null`.
