 169 // of CreateRenderViewForRenderManager when more complicated tests start using
 170 // this.
 171 //
 172 // Note that users outside of content must use this class by getting
 173 // the separate RenderViewHostTester interface via
 174 // RenderViewHostTester::For(rvh) on the RenderViewHost they want to
 175 // drive tests on.
 176 //
 177 // Users within content may directly static_cast from a
 178 // RenderViewHost* to a TestRenderViewHost*.
 179 //
 180 // The reasons we do it this way rather than extending the parallel
 181 // inheritance hierarchy we have for RenderWidgetHost/RenderViewHost
 182 // vs. RenderWidgetHostImpl/RenderViewHostImpl are:
 183 //
 184 // a) Extending the parallel class hierarchy further would require
 185 // more classes to use virtual inheritance.  This is a complexity that
 186 // is better to avoid, especially when it would be introduced in the
 187 // production code solely to facilitate testing code.
 188 //
 189 // b) While users outside of content only need to drive tests on a
 190 // RenderViewHost, content needs a test version of the full
 191 // RenderViewHostImpl so that it can test all methods on that concrete
 192 // class (e.g. overriding a method such as
 193 // RenderViewHostImpl::CreateRenderView).  This would have complicated
 194 // the dual class hierarchy even further.
 195 //
 196 // The reason we do it this way instead of using composition is
 197 // similar to (b) above, essentially it gets very tricky.  By using
 198 // the split interface we avoid complexity within content and maintain
 199 // reasonable utility for embedders.
