@Test public void deleteVnfTest() { MsoRequest msoRequest = new MsoRequest(); msoRequest.setRequestId("12345"); msoRequest.setServiceInstanceId("12345"); instance.deleteVnfA("mdt1", "CloudOwner", "88a6ca3ee0394ade9403f075db23167e", "vSAMP12", "messageId", msoRequest, "http: assertNotNull(msoRequest); }
