我有一個使用spring驗證器的用戶驗證器的書面單元測試用例。下面是類。我在Spring驗證器的validate方法中面臨問題，調用服務來檢查用戶是否爲admin。但是管理服務會引發異常。所以我用try catch塊覆蓋。現在對於單元測試用例，我收到了錯誤。如何解決java.lang.AssertionError：期望的異常：Mockito中的java.lang.Exception

public class UserValidator implements Validator {

@Override

public boolean supports(Class clazz) {

return User.class.equals(clazz);

}

@Override

public void validate(Object target, Errors errors) {

User user = (User) target;

if(user.getName() == null) {

errors.rejectValue("name", "InValid user");

}

//try catch block because adminservice throws exeption

try{

AdminUser adminUser= adminservice.CheckAdmin(user.getId);

}

Catch(Exception e){

e.printStackTrace

}

}

}

Public uservAlidatorTest(){

@before

//set up done

@test(expected= Exception.class)

public testException(){

User user= new user();

user.setId("JUNK");

mockito.when(adminservice.CheckAdmin(user.getId)).thenThrow(new Exception("Invalid user"))

BindException error = new BindException(User, "user");

UserValidator(user,error);

}

}

錯誤跟蹤：

你想抓住哪個異常？是全部嗎？也許你實際上在更深層次上有bug。可以肯定的是，使用這個集合，你的單元測試總是會失敗。如果你需要捕獲一個你不知道的異常，那就趕上那個特定的類型，儘管你已經拋出了一個已知的異常，但我會建議你先解決這個問題。 –
