JUnit 4.8.1/Maven平凡測試不起作用

Question

雖然我嘗試了所有我發現的建議，但仍然無法獲得最平常的JUnit測試運行。該錯誤消息基本上重複說「junit.framework.AssertionFailedError：沒有在project002.trivial.TestClassTest中找到測試」。您可以檢查a snapshot of my IDE或download the zipped project。

這裏是我的pom.xml：

    </build> 
</project> 

以下是錯誤消息：

Answer 1

有一些問題與您的測試用例。當您擴展Testcase時，它將始終使用Junit 3.x執行，因此您需要在測試方法前加上「test」。

如果您想使用junit 4.x，請刪除「extends Testcase」，然後使用@Test註釋您的測試方法。

這一個運行使用JUnit 3.x和它不會工作，因爲你的測試方法不以 「test」 爲前綴： -

public class TestClassTest extends TestCase { 

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

這人會在JUnit 4.x的運行： -

public class TestClassTest { 

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