java - 使用 Maven 进行 Junit 测试时初始化错误

Question

我正在尝试使用 Maven3 进行一些 Junit 测试，但在执行具有 JUnit 注释的测试时总是会出现一些初始化错误(这里是一些测试类)(所有其他测试都运行良好)。当我在 Eclipse 中运行测试时一切都很好。但是用 Maven 运行测试会失败。我的测试项目打包为 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 {...

对于每个用 @ContextConfiguration 注释的测试类，都有 classname-test.xml 文件。在此配置文件中，我通过“classpath:”导入 applicationContext-Test.xml

我的测试插件的 pom.xml 如下所示:

<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“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？但如何正确地做到这一点呢？

Answer 1

请确保您的测试用例类 ArtifactManagerTest 中的 @BeforeClass 和 @AfterClass 方法是“public static void”并且没有参数 .

编辑:当验证@BeforeClass和@AfterClass失败时，会抛出InitializationError，因此@BeforeClass是甚至没有被处决。

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); 
}
