问题
I have added a gpx file to my project; its name is TrailOfHistory.gpx. I have edited my project's scheme so that this file will be used by Xcode 9 to perform locations updates.
Here are screen shots of the scheme's Run and Test configurations wherein I have designated that the gpx file should be used:
When I run my application, user location updates (as given by the gpx file) begin automatically. I can watch this happening on my application's MKMapView.
In contrast, when I run one of my unit tests, user location updates do not begin automatically. I must instead perform the manual step of clicking the debug toolbar's Simulate Location button and choosing the gpx file; as shown in the following screen shot:
My ultimate goal is to arrive at a set of tests that can be executed by a continuous integration system. So, clicking on Xcode buttons is not going to fly.
Can anyone provide insight on this? In particular, can anyone say that he/she has had the experience of creating an XCTest wherein location updates began automatically (if so then I'll proceed with hope; currently I am unclear what expectations I should have)?
Note: I found this very similar question, over a year old. Hopefully I can generate some renewed interest.
