>+        [macOS] [WK2] Add infrastructure to test receiving file promises on drop
>+        https://bugs.webkit.org/show_bug.cgi?id=188583
>+
>+        Reviewed by Andy Estes.
>+
>+        Enable testing file promise drop handling on the WebKit2 port of macOS by introducing a subclass of
>+        NSFilePromiseReceiver and implementing `-enumerateDraggingItemsWithOptions:forView:â¦` on TestDraggingInfo (the
>+        concrete NSDraggingInfo implementation used by DragAndDropSimulator) using the mock file receiver. Also
>+        introduces 3 new macOS tests. See below for more details.
>+
>+        A large portion of this logic is ported over from DumpRenderTree testing infrastructure added in r229297. In a
>+        future patch, we should introduce a way to write code common to both API tests, WebKitTestRunner and
>+        DumpRenderTree, and make this code shared among all three testing harnesses.
>+
>+        Tests:  DragAndDropTests.DragImageElementIntoFileUpload
>+                DragAndDropTests.DragPromisedImageFileIntoFileUpload
>+                DragAndDropTests.DragImageFileIntoFileUpload
>+
>+        * TestWebKitAPI/TestWebKitAPI.xcodeproj/project.pbxproj:
>+        * TestWebKitAPI/Tests/WebKitCocoa/DragAndDropTests.mm:
>+        (TEST):
>+
>+        Drive-by fix: Replace NSMakePoint with CGPointMake.
>+
>+        * TestWebKitAPI/Tests/WebKitCocoa/image-and-file-upload.html:
>+
>+        Add a new test page consisting of an image and a "file upload" area that updates exercises DataTransfer API to
>+        load the dropped image.
>+
>+        * TestWebKitAPI/Tests/mac/DragAndDropTestsMac.mm:
>+        (waitForConditionWithLogging):
>+
>+        Add a helper function to wait for a condition to evaluate to true. To make failures more informative,
>+        additionally add a mechanism to log a warning message after a given timeout, if the condition has yet to be met.
>+
>+        (TEST):
>+
>+        Add new tests to exercise a few cases of file upload in WebKit, including: (1) dragging from an image element,
>+        (2) dragging files written to the pasteboard as promises, and (3) files written to the pasteboard as file URLs.
>+
>+        * TestWebKitAPI/cocoa/DragAndDropSimulator.h:
>+
>+        Surface the new functionality provided by the file promise receiver mock via two new methods on
>+        DragAndDropSimulator to (1) write files as file promises to the pasteboard, and (2) write files as file paths
>+        directly to the pasteboard.
>+
>+        * TestWebKitAPI/mac/DragAndDropSimulatorMac.mm:
>+        (-[DragAndDropSimulator performDragInWebView:atLocation:withImage:pasteboard:source:]):
>+        (-[DragAndDropSimulator externalPromisedFiles]):
>+        (getFilePathsAndTypeIdentifiers):
>+        (-[DragAndDropSimulator writePromisedFiles:]):
>+        (-[DragAndDropSimulator writeFiles:]):
>+        * TestWebKitAPI/mac/TestDraggingInfo.h:
>+        * TestWebKitAPI/mac/TestDraggingInfo.mm:
>+        (-[TestDraggingInfo initWithDragAndDropSimulator:]):
>+        (-[TestDraggingInfo filePromiseReceivers]):
>+        (-[TestDraggingInfo enumerateDraggingItemsWithOptions:forView:classes:searchOptions:usingBlock:]):
>+
>+        Implement this by invoking the given block with a TestFilePromiseReceiver. While all other classes are
>+        unhandled by this testing code, WebKit only calls into this with [NSFilePromiseReceiver class], this is
>+        currently sufficient for testing purposes.
>+
>+        * TestWebKitAPI/mac/TestFilePromiseReceiver.h: Copied from Tools/TestWebKitAPI/mac/TestDraggingInfo.h.
>+        * TestWebKitAPI/mac/TestFilePromiseReceiver.mm: Added.
>+        (-[TestFilePromiseReceiver initWithPromisedTypeIdentifiers:dragAndDropSimulator:]):
>+        (-[TestFilePromiseReceiver fileTypes]):
>+        (-[TestFilePromiseReceiver fileNames]):
>+        (-[TestFilePromiseReceiver dealloc]):
>+        (-[TestFilePromiseReceiver draggingSource]):
>+        (-[TestFilePromiseReceiver setDraggingSource:]):
>+        (fileNameWithNumericSuffix):
>+        (copyFile):
>+
>+        Add a helper to copy a file into a destination directory. Used to implement the main functionality of our
>+        NSFilePromiseReceiver subclass, which copies the files specified by test code into the directory determined by
>+        WebKit.
