Do we need to prefix all actions with WebView? We don't prefix matchers AFAIK

[baxley, 2017/03/24 16:48:07]

Probably not. I have a bug I'm looking at to get rid of matchers that wait, so
most (all?) of these would go away. I'll leave this as is, and choose better
names when they move to ChromeEarlGrey[UI]

                                               id<GREYAction> action,
                                               const std::string& element_id);
 
 // Executes a longpress on element |element_id| in the webview of
 // |state|. If |triggers_context_menu| is true, this gesture is expected to
 // cause the context menu to appear, and is not expected to trigger events
 // in the webview. If |triggers_context_menu| is false, the converse is true.
 // This action doesn't fail if the context menu isn't displayed; calling code
 // should check for that separately with a matcher.
