The idea would be to eliminate code like this (that's brittle and often fails on a different platform): var root = accessibilityController.rootElement; var table = root.childAtIndex(0).childAtIndex(0); ...and replace it with: var root = accessibilityController.accessibleElementById('table_0');

(A few layout tests used to repro crash bugs walk every element in the tree using JS now, this would be far easier.) * Finally, I don't think that speed is as important for code that's only used for testing; the accessibility layout tests are all pretty fast now and exploring the whole tree doesn't affect their runtime >> Tools/DumpRenderTree/chromium/TestRunner/AccessibilityControllerChromium.cpp:106 >> + for (unsigned i = 0; i < obj.childCount(); i++) { > > obj.childCount() should be in a variable so you don't have to call a method each time through the loop Done >> Tools/DumpRenderTree/chromium/TestRunner/AccessibilityControllerChromium.cpp:187 >> + result->setNull(); > > can you set result->setNull() at the top of the method and then just return right away on the error conditions? > that will make it a tad cleaner and remove the need for brackets Sure, that's cleaner. >> Tools/DumpRenderTree/mac/AccessibilityControllerMac.mm:43 >> +#define END_AX_OBJC_EXCEPTIONS } @catch(NSException *e) { if (![[e name] isEqualToString:NSAccessibilityException]) @throw; } > > we should find a way to only define this once since it's also defined in AXUIElement Moved to a common header file. >> Tools/DumpRenderTree/mac/AccessibilityControllerMac.mm:54 >> + return NULL; > > we should return nil for ObjC objects Done >> Tools/DumpRenderTree/mac/AccessibilityControllerMac.mm:103 >> + NSArray* children = [obj accessibilityAttributeValue:NSAccessibilityChildrenAttribute]; > > since this is an ObjC object the * should be next to the "children" > http://www.webkit.org/coding/coding-style.html#pointers-non-cpp > > same goes for NSString* idAttribute Done >> Tools/DumpRenderTree/mac/AccessibilityControllerMac.mm:104 >> + for (NSUInteger i = 0; i < [children count]; ++i) { > > [children count] should be in a variable so we don't have to call the method each time through the loop Done >> Tools/DumpRenderTree/mac/AccessibilityControllerMac.mm:120 >> + else > > no need for else here Done >> Tools/WebKitTestRunner/InjectedBundle/AccessibilityController.h:51 >> + PassRefPtr<AccessibilityUIElement> accessibleElementById(JSStringRef attribute); > > attribute should probably be "id" Named it idAttribute to not conflict with the obj-C type "id". >> Tools/WebKitTestRunner/InjectedBundle/mac/AccessibilityControllerMac.mm:61 >> + return [(NSString *)cfString autorelease]; > > same comments as DRT Done
The style checker doesn't seem to realize that AccessibilityCommonMac.h is an objective-C file. Should I name it .hh? Why don't other obj-C header files ending in .h have the same problem? Or is there something else I'm missing?

Or is there something else I'm missing? Maybe a bug in the style checker? ObjC headers are always .h in all code I've ever seen

Just ignore it — StyleQueue isn't the final say. Thanks for taking a look! I'll ignore it, and now that the impl is in a .mm file, there are no other warnings. >> Tools/DumpRenderTree/mac/AccessibilityCommonMac.h:64 >> +@end > > The @implementation should not be in a .h file. If it was in a .m file it would be fine. I'm surprised this builds. Fixed.
