使用Maven进行单元测试时的初始化错误

我正在尝试使用Maven3进行一些Junit-Test，但在执行具有JUnit-Annotations的测试时（所有其他测试运行正常），总会得到一些initilizationError（这里有一些testclass）。当我在Eclipse中运行测试时，一切都很好。但是用maven运行测试会破坏。 我的Testproject打包为eclipse-plugin。 我使用maven-osgi-test-plugin。

我的测试类注释为：

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations="classpath:applicationContext.xml")
@TransactionConfiguration
public class ArtifactManagerTest extends
    AbstractTransactionalJUnit4SpringContextTests {...

对于使用@ContextConfiguration注释的每个测试类，都有classname-test.xml文件。在此配置文件中，我通过“classpath：”

导入applicationContext-Test.xml

我的test-plugin的pom.xml看起来像：

<groupId>foo.bar</groupId>
<artifactId>company.xyz</artifactId>
<version>1.0.0-SNAPSHOT</version>
<packaging>eclipse-test-plugin</packaging>

<build>
 <plugins>
  <plugin>
   <groupId>org.sonatype.tycho</groupId>
   <artifactId>maven-osgi-test-plugin</artifactId>
   <configuration>
    <useUIHarness>true</useUIHarness>
    <testSuite>company.xyz.test</testSuite>
    <testClass>company.xyz.AllTests</testClass>
    <argLine>-Xmx512m</argLine>
    <bundleStartLevel>
     <bundle>
      <id>org.eclipse.equinox.ds</id>
      <level>1</level>
      <autoStart>true</autoStart>
     </bundle>
    </bundleStartLevel>
   </configuration>
   <inherited>true</inherited>
  </plugin>
 </plugins>
</build>

失败输出如下：

在surefire-reports中，我看到java.class.path设置为我的本地maven存储库为'org.eclipse.equinox.launcher-1.1.0.v20100507.jar'

看起来类路径设置不正确，所以maven找不到applicationContext.xml？但是如何做到这一点呢？

答案 0 :(得分：1)

请确保您的测试用例类ArtifactManagerTest中@BeforeClass和@AfterClass的方法“public static void”且无参数。

修改：验证InitializationError和@BeforeClass失败时会引发@AfterClass，因此@BeforeClass甚至都没有执行。

如果可能，请使用以下代码获取失败信息：

Result r=new JUnitCore().run(ArtifactManagerTest.class); 
for(Failure f:r.getFailures()){ 
    System.out.println(f); 
}
