为什么我的 @BeforeClass 方法没有运行?

问题描述

我有以下代码:

    @BeforeClass
    public static void setUpOnce() throws InterruptedException {
        fail("LOL");
    }

以及各种其他方法，例如 @Before、@After、@Test 或 @AfterClass 方法.

And various other methods that are either @Before, @After, @Test or @AfterClass methods.

测试在启动时并没有像它看起来应该的那样失败.有人可以帮帮我吗?

The test doesn't fail on start up as it seems it should. Can someone help me please?

我有 JUnit 4.5

I have JUnit 4.5

该方法在立即调用 setUp() 时失败，注释为 @before.类定义是:

The method is failing in an immediate call to setUp() which is annotated as @before. Class def is :

public class myTests extends TestCase {

推荐答案

不要同时扩展 TestCase 和使用注解！
如果您需要创建带有注释的测试套件，请使用 RunWith 注释，例如:

do NOT extend TestCase AND use annotations at the same time!
If you need to create a test suite with annotations, use the RunWith annotation like:

@RunWith(Suite.class)
@Suite.SuiteClasses({ MyTests.class, OtherTest.class })
public class AllTests {
    // empty
}


public class MyTests {  // no extends here
    @BeforeClass
    public static void setUpOnce() throws InterruptedException {
        ...
    @Test
    ...

(按照惯例:类名用大写字母)
