XCode7 UITests how to test screen edge pan gestures?

问题

I have the following gesture recognizer in my app. I've looked at xCode7 UI and see that it has swipe up/down/left/right, but no pan or edge pan gestures.

How can one test or initiate screen edge pan gesture for UITesting purposes?

  UIScreenEdgePanGestureRecognizer *leftEdgeGesture = [[UIScreenEdgePanGestureRecognizer alloc] initWithTarget:self action:@selector(show)];
    leftEdgeGesture.edges = UIRectEdgeLeft;
    leftEdgeGesture.delegate = self;
    [self.view addGestureRecognizer:leftEdgeGesture];

I spent a while trying to figure this out, navigating around the element hierarchy. Lots and lots of googling and finding nothing.

I gave up twice, then figured it out.

We just need two coords on the main app screen, and drag one to the other.

Works a treat!

XCUIApplication *app = [[XCUIApplication alloc] init];
[app launch];

// Set a coordinate near the left-edge, we have to use normalized coords
// so you set using percentages, 1% in on the left, 15% down from the top
XCUICoordinate *coord1 = [app coordinateWithNormalizedOffset:CGVectorMake(0.01, 0.15)];

// Then second coordinate 40 points to the right
XCUICoordinate *coord2 = [coord1 coordinateWithOffset:CGVectorMake(40, 0)];

// Perform a drag from coord1 to coord2
// Simulating swipe in from left edge
[coord1 pressForDuration:0.5f thenDragToCoordinate:coord2];

Hopefully this will help everyone else who has been struggling to simulate an edge swipe.
