java - 尝试在 Spring WebFlow 项目的服务级别上运行 junit 测试。假设$AssumptionViolatedException

Question

我正在尝试使用 junit 在 Eclipse 中的 Spring Web Flow 项目上运行我的第一个测试，也从控制台使用 mvn test 运行我的第一个测试，但给了我同样的错误。

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("cpilling04@aol.com.dev");


        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——但我在春天的论坛上找到了这个。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，看看问题是否消失。

Answer 2

我必须保留 Spring v2.5，降级到 JUnit 4.4 可以解决问题。

此外，您会看到 Assume$AssumptionViolatedException 隐藏的原始原因；）

仅供参考，迁移到最新的 spring-test 2.5.6 不会改变任何东西。

链接 SO：Junit4 + Spring 2.5：断言抛出“NoClassDefFoundError”

Answer 3

我不得不将我的 spring-test 和 junit 版本都升级到最新版本，并且一切正常！

Answer 4

我发现 spring-test 2.5.x 期望 org.junit.Assume 包含 AssumptionViolatedException，但在 junit 4.10 中它已被移至 org.junit.internal 包。测试将停止运行（不会失败）并出现 ClassNotFoundException。

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）。必须将此本地副本添加到类路径中，首先是您的 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过时，代码的未来用户可能不知道它的存在；这是等待发生的未来失败。

此外，它可能不会先加载。为了缓解这种情况，我添加了检查 Assume 是否首先加载的测试，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");
        }
    }
}
