java - junit 测试用例通过，但仍在控制台 java 中打印异常

Question

@Test
public void testGetAspectByAspectName() {
    try {
    this.getUserTwin();
    assertEquals(userAlmService.getAspectByUserName("6cade-bced-4e69-8red-271c95d343baa", null).toString(),this.getAspect().toString());
    }
    catch (NullPointerException e) {
        assertEquals(NullPointerException.class, e.getClass());
    }
}

我的目的是检查空指针异常。测试用例通过了，但我在控制台中收到 NULL 异常消息如何限制不在控制台中打印我尝试了 @Test(expected=NullPointerexception.class) 仍然在控制台中打印

java.lang.NullPointerException: null

我正在使用 sprinrunner

@RunWith(SpringRunner.class)
@SpringBootTest

试试这个:

@Rule
public ExpectedException exception = ExpectedException.none();
@Test
public void fooBar() throws FooBarException {
    exception.expect(FooBarException.class);
    exception.expectMessage(containsString("bla bla bla"));
    //your code here
}
