Question

虽然我尝试了我发现的所有建议，但我仍然无法进行最简单的JUnit测试。错误消息基本上重复说“junit.framework.AssertionFailedError：在project002.trivial.TestClassTest中找不到测试”。

您可以查看a snapshot of my IDE或download the zipped project。

这是我的pom.xml：

Answer 1

您的测试用例有问题。当您扩展Testcase时，它将始终使用Junit 3.x执行，因此您需要在测试方法前加上“test”。

如果要使用junit 4.x，请删除“extends Testcase”，然后使用@Test注释您的测试方法。

这个使用Junit 3.x运行，它不起作用，因为你的测试方法没有以“test”为前缀： -

public class TestClassTest extends TestCase {

    @Test
    public void isThisReallyTrue() {
        assertTrue(true);
    }
}

这个将在Junit 4.x中运行： -

public class TestClassTest {

    @Test
    public void isThisReallyTrue() {
        assertTrue(true);
    }
}

JUnit 4.8.1 / Maven琐碎测试不起作用
