Unit-Tests für das flurstueck_alkis-Modul.
|
||
|
||
Getestet werden:
|
||
- Nutzerabbruch bei ask_text → (None, LoadStatus.NONE)
|
||
- Ungültiger WFS-Layer → (None, LoadStatus.NONE)
|
||
- Erfolgreicher Ladevorgang → gültiger Layer + LoadStatus.FIRST
|
||
- Bestehender Layer: Nutzer wählt "Neu laden" → LoadStatus.RELOAD
|
||
- Bestehender Layer: Nutzer wählt "Behalten" → LoadStatus.KEEP
