### Question:
DownloadFileService implements Constants { public List<Map<String, Object>> getAllAssetGroupApis() { return repository.getDataFromPacman(assetGroupQuery); }  List<Map<String, Object>> getAllAssetGroupApis(); void downloadData(final HttpServletResponse servletResponse, final JsonArray response,
            final String fileFormat, String methodType);  }### Answer:
@Test public void getAllAssetGroupApisTest() throws Exception { when(repository.getDataFromPacman(anyString())).thenReturn(CommonTestUtil.getListMapObject()); ReflectionTestUtils.setField(downloadFileService, "assetGroupQuery", "dummyEsURL"); assertThat(downloadFileService.getAllAssetGroupApis(), is(notNullValue())); }
