Die App verfügt derzeit nur über grundlegende UI-Tests aus folgenden Gründen:
|
||||||
|
|
||||||
|
1. **HTTP Requests im LocationSelector**:
|
||||||
|
- Die Klasse LocationSelector verwendet HTTP-Anfragen, um Standortinformationen abzurufen.
|
||||||
|
- Beim Testen in einer Flutter-Testumgebung wird jedoch keine tatsächliche Netzwerkanfrage ausgeführt:
|
||||||
|
> Warning: At least one test in this suite creates an HttpClient. When running a test suite that uses
|
||||||
|
> TestWidgetsFlutterBinding, all HTTP requests will return status code 400, and no network request
|
||||||
|
> will actually be made. Any test expecting a real network connection and status code will fail.
|
||||||
|
> To test code that needs an HttpClient, provide your own HttpClient implementation to the code under
|
||||||
|
> test, so that your test can consistently provide a testable response to the code under test.
|
||||||
|
- Offenbar müssten HTTP-Anfragen gemockt oder gefaked werden, was zusätzliche Komplexität und Aufwand verursacht.
|
||||||
|
- Es existieren zusätzliche Paketen wie `http_mock_adapter` oder `mockito`, um Anfragen zu simulieren und Antworten zu erzeugen, diese erfordern aber eine zeitaufwändigere Integration und Konfiguration als die übrigen Tests.
|
||||||
|
|
||||||
|
2. **Nutzung von Firebase**:
|
||||||
|
- Die App nutzt Firebase-Dienste, die in einer Testumgebung ebenfalls nicht ohne weiteres funktionieren.
|
||||||
|
- Versuche, Firebase-Dienste zu verwenden, endeten stets mit der Meldung: "Unable to establish connection on channel".
|
||||||
|
- Auch hier wäre es notwendig, die Firebase-Dienste zu mocken oder zu faken, was ebenfalls mühsam und komplex ist.
|
||||||
|
- Es gibt offenbar einige Pakete wie `firebase_mocks`, die dabei helfen können, aber diese erfordern eine sorgfältige (und für mich aktuell leider zu zeitaufwendige) Einrichtung und ggf. Überarbeitung der Architektur.
|
||||||
|
|
||||||
|
Diese Umstände machten es schwierig, vollständige UI-Tests zu erstellen, was sich in der minimalistischen Anzahl der vorhandenen UI-Tests widerspiegelt.
