单元测试 - mock异常

Posted 2022-03-27 jylsgup

最近在使用mock进行单元测试的时候，遇到了下面的问题：

org.mockito.exceptions.misusing.InvalidUseOfMatchersException:
Invalid use of argument matchers!
1 matchers expected, 2 recorded:
-> at com.xxx.xxx.clearing.mock.AccountUpdateMock.execute(AccountUpdateMock.java:38)
-> at com.xxx.xxx.clearing.mock.AccountUpdateMock.execute(AccountUpdateMock.java:38)

This exception may occur if matchers are combined with raw values:
//incorrect:
someMethod(anyObject(), "raw String");
When using matchers, all arguments have to be provided by matchers.
For example:
//correct:
someMethod(anyObject(), eq("String by matcher"));

For more info see javadoc for Matchers class.

 

看提示是告诉我们，如果有一个参数用了匹配，那么所有的参数都必须采用匹配。

 

但是我的用法是：

public List<Account> getUpdateAccountList(Date startDate, Date endDate) 
    AccountQuery param = new AccountQuery();
    param.setUpdateTimeStart(startDate);
    param.setUpdateTimeEnd(endDate);
    return accountService.updateAccountList(param);


然后mock：

Mockito.when(prepare.getUpdateAccountList(Mockito.any(), Mockito.any())).thenReturn(accMods);
两个参数均是用的any匹配，还是报上述错误。

后面有两种办法解决：
方法1：定义一个 
Date date = Mockito.any();      

Mockito.when(prepare.getUpdateAccountList(date, date)).thenReturn(accMods);

方法2：

public List<Account> getUpdateAccountList(AccountQuery param) 

    return accountService.updateAccountList(param);

初步怀疑是，因为两个参数都是Date类型，两个any匹配出错。
