setTestProviderLocation löst onLocationChanged im Service-Testfall nicht aus

Question

Ich habe kleinen Dienst implementieren LocationListener. Ich habe es manuell mit meiner Anwendung getestet und es funktioniert einwandfrei. Ich habe auch einen Testfall für den Dienst geschrieben. Ich habe setTestProviderLocation in der Erwartung verwendet, dass der Dienst eine Standortaktualisierung erhält. Dies ist jedoch nicht der Fall. Weiß jemand, wo das Problem liegt? Ich möchte betonen, dass der gleiche Dienst in der realen Anwendung funktioniert. Der Testfall ist unten hinzugefügt
