WebKit (or at least Chrome) is currently failing a bunch opera's tests located at: http://tc.labs.opera.com/apis/XMLHttpRequest/ It seems that it would be a good idea for us to make use of these tests in WebKit, so I was thinking of importing them into the codebase. This raises the question: Should we import the tests one at a time as we fix the bugs, or should we import the whole suite? The tests look like they will fit into the existing LayoutTests infrastructure pretty easily, but if we import the whole lot it would be good to figure out if it is possible to keep our copy in sync with Opera's, possibly along the lines of WebKitTools/Scripts/update-webgl-conformance-tests . Should they end up in a subdirectory of LayoutTests/http/tests? (They require php scripts on the server). Thanks, Luke
