Run UI Test with map view in iOS

Mock a location

You should mock a location to ensure reliable test

Create the gpx file

Go to Xcode -> File -> New -> GPX File

It looks like

<?xml version="1.0"?>
<gpx version="1.1" creator="Xcode">
  <wpt lat="59.913590" lon="10.733750">
    <name>Oslo S</name>
    <time>2017-05-31T14:55:37Z</time>
  </wpt>
  <wpt lat="59.913590" lon="10.733750">
    <name>Oslo S</name>
    <time>2017-05-31T14:55:40Z</time>
  </wpt>
</gpx>
Enter fullscreen mode Exit fullscreen mode

The gpx file is very powerful, as it allows you to specify a route with different movement speed.

Provide one or more waypoints containing a latitude/longitude pair. If you provide one
waypoint, Xcode will simulate that specific location. If you provide multiple waypoints,
Xcode will simulate a route visiting each waypoint.

Optionally provide a time element for each waypoint. Xcode will interpolate movement
at a rate of speed based on the time elapsed between each waypoint. If you do not provide
a time element, then Xcode will use a fixed rate of speed. Waypoints must be sorted by time in ascending order.

Use the gpx file

  • Declare the gpx file in app target, not UITests target. Go to your app scheme -> Run -> Options

  • Go to Simulator -> Debug -> Location -> Custom Location and select that same location, just to make sure. It does not need to be the same, but I see that without Custom Location, it does not work in UITests

Test that you’re near the initial location

let map = app.maps.element(boundBy: 0)
let predicate = NSPredicate(format: "label CONTAINS 'City Hall'")
let cityHall = map.otherElements.matching(predicate).element(boundBy: 0)

// wait for the map to finish loading and zooming
wait(for: cityHall, timeout: 2)
XCTAssertTrue(cityHall.exists)
Enter fullscreen mode Exit fullscreen mode

The wait function is from #44

Test that you can interact with your custom pin

You need to specify accessibilityIdentifier, like

class MyPin: MKAnnotationView {
  override func didMoveToSuperview() {
    super.didMoveToSuperview()

    accessibilityIdentifier = "myPin"
  }
}
Enter fullscreen mode Exit fullscreen mode

and then query for that pin. Not that it is not inside map, it is inside app

let pin = app.otherElements.matching(identifier: "myPin").element(boundBy: 0)
XCTAssertTrue(pin.exists)
Enter fullscreen mode Exit fullscreen mode




You should use accessibilityIdentifier

accessibilityIdentifier is from UIAccessibilityIdentification protocol. You should not use accessibilityLabel, see kif-framework/KIF#243

Given that accessibilityLabel is an outwardly-facing string that is actually used by accessibility screen readers (and should be localized to the device user’s language), Apple now provides an alternate property (iOS 5+) that is specifically intended for UI Automation purposes
