// TestRenderViewHost ----------------------------------------------------------
// TODO(brettw) this should use a TestWebContents which should be generalized
// from the WebContentsImpl test. We will probably also need that class' version
// of CreateRenderViewForRenderManager when more complicated tests start using
// this.
// Note that users outside of content must use this class by getting
// the separate RenderViewHostTester interface via
// RenderViewHostTester::For(rvh) on the RenderViewHost they want to
// drive tests on.
// Users within content may directly static_cast from a
// RenderViewHost* to a TestRenderViewHost*.
// The reasons we do it this way rather than extending the parallel
// inheritance hierarchy we have for RenderWidgetHost/RenderViewHost
// vs. RenderWidgetHostImpl/RenderViewHostImpl are:
// a) Extending the parallel class hierarchy further would require
// more classes to use virtual inheritance. This is a complexity that
// is better to avoid, especially when it would be introduced in the
// production code solely to facilitate testing code.
// b) While users outside of content only need to drive tests on a
// RenderViewHost, content needs a test version of the full
// RenderViewHostImpl so that it can test all methods on that concrete
// class (e.g. overriding a method such as
// RenderViewHostImpl::CreateRenderView). This would have complicated
// the dual class hierarchy even further.
// The reason we do it this way instead of using composition is
// similar to (b) above, essentially it gets very tricky. By using
// the split interface we avoid complexity within content and maintain
// reasonable utility for embedders.
