Question

我是junits的新手。当我尝试运行我的测试套件时，它给了我这个错误。我用Google搜索但没有得到任何答案。发布堆栈跟踪。

这是我试图运行的测试套件。

@RunWith(Categories.class)
@Categories.IncludeCategory(DCCTests.class)
@SuiteClasses({ AllTests.class })
public class DealerCommandCenterTestsSuite {

}

Answer 1

我在What is Junit trying to tell me when it throws a "NoTestsRemainException"中讨论了一个类似的问题，我的原因是加载了一个过时的JUnit jar版本3.8而不是所需的JUnit 4.11。

Answer 2

以下是@Category的工作示例（该示例来自Java Doc）。它适用于我的JUnit 4.11

org.junit.experimental.categories.Categories

public interface FastTests {
 }

 public interface SlowTests {
 }

 public static class A {
    @Test
    public void a() {
        fail();
    }

    @Category(SlowTests.class)
    @Test
    public void b() {
    }
 }

 @Category( { SlowTests.class, FastTests.class })
 public static class B {
    @Test
    public void c() {

    }
 }

 @RunWith(Categories.class)
 @IncludeCategory(SlowTests.class)
 @SuiteClasses( { A.class, B.class })
 // Note that Categories is a kind of Suite
 public static class SlowTestSuite {
 }

主要致电：

public static void main(String[] args)
    {
        Result result  = JUnitCore.runClasses(SlowTestSuite.class);

        /** Check results **/
    }

Answer 3

该消息在技术上对您的样本是正确的，但非常误导。

org.junit.runners.AllTests.class不是@SuiteClasses的有效参数（它应该是一个JUnit 3.8适配器），因此Categories运行器会在内部丢弃它，然后报告它有＆＃34; no剩下的测试＆＃34;跑。

我认为不完整的错误处理与＆＃34;实验＆＃34;类别的Java包的一部分，现在JUnit 5中新的@Tag注释已弃用。

如果需要动态地包含类路径中类中包含的所有测试，请尝试以下线程：How do I Dynamically create a Test Suite in JUnit 4?
