Wie verspotte ich eine Klasse, deren Feld auf System.getEnv("...") gesetzt ist? ⇐ Java

[Guest]

Ich versuche, einen Komponententest für eine Klasse zu schreiben, deren Variablenwert auf System.getEnv("...") gesetzt ist. Jetzt erhalte ich beim Ausführen der Testklasse einen Initialisierungsfehler. Ich habe versucht, die Systemklasse zu verspotten, aber ohne Erfolg. Was kann hier getan werden, um die Testklasse auszuführen?
