Current Android build setup on Azure DevOps misses testing on Android:

Since the tests that are based on ctest are not simply runnable on Android, we first have to convert existing tests into runnable style in Android manner. A dedicated test runner application would suffice.

As commented on the issue linked above, I came up with such a solution (test generator + runnable setup). A PR will follow and be linked here. So far it lacks the actual Azure DevOps setup, but having a locally runnable test app would be a good starter.
