Really important!! This test is designed to ensure that the members
|
|
which usually belong to a QgsApplication instance are still usable
|
|
when no QgsApplication instance is available (eg when using
|
|
custom editor widgets in QtDesigner). In this case QgsApplication
|

falls back to static members, which this test is designed to check.

So don't add start_app here or anything else which creates a

QgsApplication instance!
