试图在Spring WebFlow Project的服务级别上运行junit测试。 假设$ AssumptionViolatedException

我试图在Eclipse中使用junit在Eclipse Web Flow Project上运行我的第一个测试，并且还使用mvn测试从控制台运行，但是给了我同样的错误。

java.lang.NoClassDefFoundError：org / junit / Assume $ AssumptionViolatedException

这是我的java代码：

package org.uftwf.memberinquiry.text; import junit.framework.Assert; import org.junit.Test; import org.junit.runner.RunWith; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.test.context.ContextConfiguration; import org.springframework.test.context.junit4.SpringJUnit4ClassRunner; import org.uftwf.memberinquiry.model.MemberInquiryInformation; import org.uftwf.memberinquiry.model.MemberRequest; import org.uftwf.memberinquiry.service.MemberInquiryService; @RunWith(SpringJUnit4ClassRunner.class) @ContextConfiguration(locations = "classpath:root-config.xml") public class TestApp { @Autowired private MemberInquiryService service; @Test public void testgetMemeberRequestInformation() { MemberRequest inMemberRequest = new MemberRequest(); MemberInquiryInformation testInfo = service.getMemeberRequestInformation(inMemberRequest); inMemberRequest.setRequestor("[e-mail]"); Assert.assertEquals(testInfo.getFirst_Name(), "Christine"); Assert.assertEquals(testInfo.getLast_Name(), "Pillings"); } } 

这是我的pox.xml

Answer 1

这是在黑暗中拍摄的 – 但我在spring的论坛上发现了这一点 。 它与您的配置一致 – 您使用的是Spring-test v2.5和Junit 4.7，看起来spring-test v2.5可能只支持Junit v4.4。

尝试降级到JUnit 4.4或升级到spring-test v2.5.6并查看问题是否消失。

Answer 2

我必须保留Spring v2.5，降级到JUnit 4.4才能解决问题。

此外，您将看到Assume $ AssumptionViolatedException隐藏的原始原因;）

仅供参考，转到最新的弹簧测试2.5.6不会改变任何东西。

Answer 3

我不得不将我的spring-test和junit版本升级到最新版本并且爆炸一切都很好！

Answer 4

我发现spring-test 2.5.x期望org.junit.Assume包含AssumptionViolatedException，但在junit 4.10中它已被移动到org.junit.internal包中。 使用ClassNotFoundException，测试将停止运行（而不是失败）。

我的解决方法是添加我自己的基于4.10的JUnit Assume副本并添加AssumptionViolatedException（来自内部）。 必须首先将此本地副本添加到类路径中，这是IDE和构建工具。

 public class Assume { /* * Ported this from JUnit 4.4 to satisfy spring-test */ public static class AssumptionViolatedException extends org.junit.internal.AssumptionViolatedException { private static final long serialVersionUID = 1L; public AssumptionViolatedException(Object value, Matcher matcher) { super(value, matcher); } } // rest of Assume from JUint 4.10 .... } 

缺点是这个类显然会很快变得陈旧，未来的代码用户可能不知道它存在; 这是未来的失败等待发生。

它也可能不会先加载。 为了缓解这种情况，我添加了一些测试，检查Assume是否先加载，如果没有则发出警告：

 import java.net.URL; public class JUnitSpringTestAssumeOverrideCompatibilityChecker { public static void checkAssumeOverridden() { URL url = Thread.currentThread().getContextClassLoader().getResource("org/junit/Assume.class"); if (!"file".equals(url.getProtocol())) { throw new RuntimeException("Expect local override (1st on classpath) of JUnit 4.10 Assume for spring-test 2.5 compatibility"); } } }
