Question

在使用正确的Mockito语法测试Spring Rest Template删除方法时，我需要帮助。

服务代码：

@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());
        }
    }

单元测试代码：

@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：

无效地使用了Mockito Matchers。预计有5个符合条件的匹配器4个。

Answer 1

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

您不应该组合蚂蚁匹配器，例如anyMap（）和anyString（）在when（）。thenReturn（）语句中具有与eq（Void.class）类似的精确值
还可以用any（）替换“ Void.class”

Answer 2

您应将Void.class包装在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输入都用ArgumentMatcher包装或不包装。
