These are WebURLLoaderMockFactory overrides, we may not really want to have
comments between methods.

Add this phrase to WebURLLoaderMockFactory.h and forward readers to
WebURLLoaderMockFactory.h to see how it can be used?

Done.

   void registerErrorURL(const WebURL& url,
                         const WebURLResponse& response,
                         const WebURLError& error) override;
