java - 为什么我的单元测试在添加参数后失败？

Question

这是我工作正常时的代码

verify(loginService).getUser(eq(loginName));

这里失败了..

@Test
public void test_getUserFlow4() {
    ...
    LoginModel loginModelReturned = loginService.getUser(loginName, null);
    assertGeneralConditions(loginModelReturned);
    ...
}

private void assertGeneralConditions(LoginModel loginModelReturned){
    verify(loginService).getUser(eq(loginName), null);  //test failed here other lines not executed
    ....
    ....
}

这是 getUser 方法

public LoginModel getUser(String loginName, String userAgent) {
    // userAgent is not being used anywhere
    ....
    return model;
}

确切错误:

org.mockito.exceptions.misusing.InvalidUseOfMatchersException: 
Invalid use of argument matchers!
2 matchers expected, 1 recorded:

如果您使用参数匹配，则需要将它们用于所有参数。因此，要修复您的测试，您可以使用:

verify(loginService).getUser(eq(loginName), Matchers.<String>eq(null));

或者:

verify(loginService).getUser(eq(loginName), (String) isNull());

或者就个人而言，我会通过简单地使用值为 null 的 userAgent 变量来澄清这一点:

String userAgent = null;
verify(loginService).getUser(eq(loginName), eq(userAgent));
