### Question:
OofUtils { public String getCamundaMsgUrl(String messageEventName, String correlator) { System.out.println(env); String camundaMsgUrl = new StringBuilder(env.getRequiredProperty(Constants.WORKFLOW_MESSAGE_ENPOINT)) .append("/").append(messageEventName).append("/").append(correlator).toString(); return camundaMsgUrl; }  String getCamundaMsgUrl(String messageEventName, String correlator); HttpHeaders getCamundaHeaders(); HttpHeaders getOofHttpHeaders(); String getOofurl(String apiPath);  }### Answer:
@Test void testGetCamundaMsgUrl() { when(env.getRequiredProperty(Mockito.anyString())).thenReturn("dummyString"); String camundamsgUrl = oofUtils.getCamundaMsgUrl("samplemessage", "sampleCorrelator"); Assertions.assertNotNull(camundamsgUrl); }
