Run UI Test with map view in iOS

#test #mapview #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>

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)

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"
  }
}

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)

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
