Sie möchten den externen Anbieter wahrscheinlich einmal testen, ihn aber nicht unbedingt bei jedem weiteren ausgeführten Test aufrufen.

In diesem Fall können Sie die Abhängigkeit, die diesen Anbieter aufruft, überschreiben und eine benutzerdefinierte Abhängigkeit verwenden, die einen Mock-Benutzer zurückgibt, nur für Ihre Tests.
