JUnit @Test 预期的注释不起作用

问题描述

我有以下测试:

@Test(expected = IllegalStateException.class)
public void testKey() {
    int key = 1;
    this.finder(key);
}

但是 JUnit 报告说，测试失败，尽管它抛出了 - 正如预期的那样 - IllegalStateException.

But JUnit reports, that the test fails, although it throws — as expected — an IllegalStateException.

我必须配置其他东西才能运行吗?

Do I have to configure something else to make this run?

我现在运行测试

@RunWith(Suite.class)
@SuiteClasses(Test.class)
public class TestSuite {

}

像 这个问题，但仍然没有得到想要的结果.

like in this question, but am still not getting the desired result.

当我删除 test 前缀时，我仍然收到错误消息.

And when I remove the test prefix I'm still getting an error.

我得说我使用 Eclipse 运行这些测试，但它被配置为使用 JUnit 4 Runner.

I gotta say that I run these tests with Eclipse, but it's configured to use the JUnit 4 Runner.

推荐答案

问题是，嵌套测试的类是 TestCase 的扩展.由于这是 JUnit 3 样式，因此注释不起作用.

The problem was, that the class in which the test was nested was an extension of TestCase. Since this is JUnit 3 style, the annotation didn't work.

现在我的测试类是一个独立的类.

Now my test class is a class on its own.
