使用Mockito測試REST刪除方法

Question

我需要使用正確的Mockito語法來測試Spring Rest Template Delete方法的幫助。

服務代碼：

@Override
    public Boolean deleteCustomerItem(String customerNumber, String customerItemId)
            throws Exception {
        Map<String, String> uriVariables = new HashMap<>();
        uriVariables.put("itemId", customerItemId);
        try {
            ResponseEntity<Void> deleteResponseEntity = restTemplate.exchange( deleteCustomerItemUrl, HttpMethod.DELETE, HttpEntity.EMPTY,
                    Void.class, uriVariables);
            return deleteResponseEntity.getStatusCode().is2xxSuccessful();
        } catch (Exception e) {
            throw new AppCustomerException(e.getMessage());
        }
    }

單元測試代碼：

@Test
    public void testDeleteCustomerItem() throws AppCustomerException {
        ResponseEntity<Void> noResponse = new ResponseEntity<Void>(HttpStatus.OK);
        when(restTemplate.exchange(anyString(), any(HttpMethod.class), any(HttpEntity.class), Void.class, anyMap()))
                .thenReturn(noResponse);
        Boolean deleteStatus = appCustomerService.deleteCustomerItem("134", "7896");
        assertEquals(Boolean.TRUE, deleteStatus);
    }

例外：

無效使用了Mockito Matchers。 預計有5個符合條件的匹配器。

Answer 1

 when(restTemplate.exchange(
      anyString(), any(HttpMethod.class), any(HttpEntity.class), 
      any(Void.class), anyMap()))
 .thenReturn(noResponse);

• 您不應該在when（）。thenReturn（）語句中將諸如anyMap（）和anyString（）之類的螞蟻匹配器與諸如eq（Void.class）之類的精確值組合在一起

• 你也可以用any（）替換“ Void.class”

Answer 2

您應該將Void.class包裝在Mockito匹配器中：

 when(restTemplate.exchange(
      anyString(), any(HttpMethod.class), any(HttpEntity.class), 
      eq(Void.class), anyMap()))
 .thenReturn(noResponse);

它的工作方式是所有輸入都被ArgumentMatcher包裝或不包裝。
