@Test public void getComplianceTrendProgressTest() throws Exception { String targetTypes = "'ec2','s3','volume'"; when(complainceRepository.getTargetTypeForAG(anyString(), anyString())) .thenReturn(targetTypes); when(complainceRepository.getRuleIdWithDisplayNameQuery(anyString())) .thenReturn(CommonTestUtil.getListMapObject()); when(complianceService.getRuleSevCatDetails(anyObject())) .thenReturn(CommonTestUtil.getListMapObject()); when(repository.getComplianceTrendProgress(anyString(),anyObject(),anyString(),anyObject())) .thenReturn(CommonTestUtil.getListMapObject()); when(complianceService.getOverallComplianceByDomain(anyString(),anyString())) .thenReturn(CommonTestUtil.getMapObject()); assertThat(issueTrendServiceImpl.getComplianceTrendProgress("ansString", LocalDate.now(),"compliance"), is(notNullValue())); }
