Interesting approach to automated map testing.

We've recently been exploring MapLibre and GeoJSON for indoor navigation applications, particularly multi-floor buildings.

One challenge I find interesting is how to validate that the correct floor plan, route and destination are displayed when the positioning system detects a floor transition.

Have you experimented with automated testing of multi-layer indoor maps, or primarily outdoor mapping applications?

Cheers, Simon
