Testing location-aware apps without moving

Ever thought you wanted a way to test your location-aware app in a (simulated) real-world environment, without actually getting off your seat? In this talk, we will explore cool ways to test your app by simulating Core Location to better mimic the real world.

2. Testing location in the real world is hard and expensive Location simulation is the key
3. How can we simulate movement? • Xcode presets • GPX track • Simulated location manager
4. How can we simulate movement? • Xcode presets • GPX track • Simulated location manager
5. Xcode preset location
6. How can we simulate movement? • Xcode presets • GPX track • Simulated location manager
7. Create a GPX file
8. GPX track
9. We did well to simulate coordinates But.. . What about the other attributes of a location?
10. CLLocation attributes • var coordinate: CLLocationCoordinate2D • var altitude: CLLocationDistance • var floor: CLFloor? • var horizontalAccuracy: CLLocationAccuracy • var verticalAccuracy: CLLocationAccuracy • var timestamp: Date • var speed: CLLocationSpeed • var course: CLLocationDirection
11. How can you simulate these attributes ?
12. How can we simulate movement? • Xcode presets • GPX track • Simulated location manager
13. Delivery of location updates Client (e.g. MyViewController) CLLocationManager 1. Start updating location 2. Deliver location updates CLLocation objects
14. Taking control over location updates Client (e.g. MyViewController) SimulatedLocationManager 1. Start updating location 3. Deliver location updates 2. Look up Location Data Custom CLLocation objects
15. LocationManagerFactory Client CLLocationManager SimulatedLocationManager Choose based on config Location Manager Factory
17. Thank you
