Junit:org.mockito.exceptions.misusing.MissingMethodInvocationException:

我正在尝试为控制器方法编写测试用例。但是我在

org.mockito.exceptions.misusing.MissingMethodInvocationException

中遇到了错误，有谁能告诉我为什么会遇到这个异常，我在测试用例中做错了什么

帐户控制器依赖于帐户服务，我正在使用mockito。为了在帐户服务中实现

populateGridView（）

，我正在使用

querydsl

AccountController

@GetMapping("/findAccountData")
    public ResponseEntity<List<Tuple>> populateGridViews(@RequestParam(value="sClientAcctId",required=false) String sClientAcctId,
                                                         @RequestParam(value="sAcctDesc",required=false) String sAcctDesc,
                                                         @RequestParam(value="sInvestigatorName",required=false)String sInvestigatorName,
                                                         @RequestParam(value="sClientDeptId",required=false) String sClientDeptId) throws Exception {
        return  ResponseEntity.ok(accService.populateGridViews(sClientAcctId, sAcctDesc,sInvestigatorName,sClientDeptId));
    }

您正在使用When-then方法。 when（）.thenReturn（）的语法为

when（mockedObject.methodName（parameter1，…，parameterN.），然后return（value）

应使用注释模拟AccountService。它不应自动连接

@Mock
private AccountService accountService;

另一件需要注意的事情是MockMvc对象不需要任何注释

private MockMvc mockMvc;

创建一个MockMvc对象就足够了。

希望对您有所帮助……

您能和我分享一下堆栈跟踪吗？我添加了堆栈跟踪。我不确定mockito的对象返回是否正确

。然后返回（accountObj）；

    Wanted but not invoked:
accountService.populateGridViews(
    "1122",
    "SRI",
    "Ram",
    "1200"
);

Actually, there were zero interactions with this mock.
