我们在maven中创建了一个用于运行我们的Selenium junit4类型测试的配置文件，下面是没有执行代码的代码片段。运行JUnit 4测试与FailSafe和SureFire插件并行
<profile>
<id>selenium-tests</id>
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-failsafe-plugin</artifactId>
<version>2.11</version>
<dependencies>
<!-- Force using the latest JUnit 47 provider -->
<dependency>
<groupId>org.apache.maven.surefire</groupId>
<artifactId>surefire-junit47</artifactId>
<version>2.11</version>
</dependency>
</dependencies>
<configuration>
<parallel>classes</parallel>
<threadCount>5</threadCount>
<forkMode>pertest</forkMode>
<useManifestOnlyJar>false</useManifestOnlyJar>
<redirectTestOutputToFile>true</redirectTestOutputToFile>
<skip>false</skip>
<includes>
<include>**/regtests/*.java</include>
</includes>
</configuration>
</plugin>
</plugins>
</build>
</profile>
而我的TestClass看起来像这样。
@RunWith(HTMLSourceDumperJUnit4Runner.class) //Our own Runner
public class MyTestClass extends Assert {
private int x = 1;
private int y = 1;
@Test
public void testAddition() {
int z = x + y;
assertEquals(2, z);
}
}
当我通过具有并行配置的故障安全插件2.11运行此测试类时，它会失败并显示以下错误。

有什么我在这里失踪。如果我对这篇文章的任何信息滞后，请回复。
你也是混合版本; surefire-junit47依赖关系应该遵循故障安全版本; 2.11而不是2.8 – krosenvold 2012-01-13 08:58:41
谢谢..我试过这个，仍然显示相同的错误。我已经用最新的尝试更新了问题。 – raksja 2012-01-14 03:25:58
只需从2.10升级到surefire 2.11，就可以打破每个单元测试的错误，包括上面的错误 - 无论是否尝试新的并行东西。所有的测试都是有效的JUnit 4类型测试，可以在2.10和之前的版本中正常工作。我花了几个小时试图弄清楚，有时间等到2.12。我所做的类似的是forkMode，useManifestOnlyJar和redirectOutputToFile设置。也许尝试不同的设置为一些或所有这些？ – 2012-01-17 04:12:24
