我正在尝试使用 @Test(expected = RuntimeException.class) 注释 为了测试预期的异常。我的代码如下:

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

                    User user = domain.save(null);

    }

我的保存方法像这样简单:

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

调试代码后，我发现代码按预期抛出异常，但它在 spring 框架类之间的某个地方被吃掉了。

我用旧方法尝试了同样的方法(try catch block )但我仍然无法在测试中捕获该异常并且测试在 Junit 的 runafter 方法中不断抛出错误:

而且我确信这是因为我在保存时抛出 RuntimeException 但无法捕获它或通过预期子句的测试。

有人知道出了什么问题吗？

最佳答案

原来我的第一个答案是错误的。 @Test(expected=...) 和@ExpectedException 都有效，但the Spring TestContext and Junit 4.5 之间存在一些不兼容问题.使用 Junit 4.4 为我解决了这个问题。最后。

关于java - Junit4 : expected=Exception not working with SPRING，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/1108066/
