Junit4：預期=異常不與春

我試圖使用@Test工作（預期= RuntimeException.class）標註在爲了測試一個預期的異常。我的代碼如下：Junit4：預期=異常不與春

@Test(expected = RuntimeException.class) 
    public void testSaveThrowsRuntimeException(){ 

        User user = domain.save(null); 

    }

和我的保存方法簡單是這樣的：

public User save(User newUser) { 
     if(newUser == null) { 
      throw new RuntimeException(); 
     } 
     //saving code goes here 
    }

調試代碼後，我發現代碼拋出異常的預期，但其得到的春天在兩者之間吃框架類。

我試着用舊的方式相同（try catch塊），但仍然我不能夠捕獲了異常的試驗和測試保持在JUnit的runafter方法引發錯誤：

而且我相信這是因爲RuntimeException我正在拋出保存但無法捕獲它或通過測試與預期的子句。

任何人有任何想法什麼問題呢？

如果Spring總是會發現異常，爲什麼要測試它呢？這是不是預期的行爲（即使不是你期望的） – 2009-07-10 07:10:10

是的，這是真的，但它後來在控制檯上拋出錯誤。所以我想自己來抓。 – ravinikam 2009-07-10 08:02:45

這裏有一個變通，我發現使用JUnit 4.5 - 在@Transactional和@ExpectedException分成嵌套函數。我想這個問題是關於aop東西春天放在@Transactional方法。

@Test 
@ExpectedException(org.springframework.dao.DataIntegrityViolationException.class) 
public void Test10UniqueName() 
{ 
    DoTest10UniqueName(); 
} 

@Transactional 
public void DoTest10UniqueName() 
{ 
    final String NAME = "NAME"; 
    ProductCategoryDAO dao = DAOFactory.getProductCategoryDAO(); 
    ProductCategory test1 = new ProductCategory(); 
    test1.setName(NAME); 
    ProductCategory test2 = new ProductCategory(); 
    test2.setName(NAME); 
    dao.save(test1); 
    dao.save(test2); 
}
