在WAS远程容器上的Arquillian和@PersistenceContext

对于我们的集成测试，我想使用Arquillian，并按照“{3}}＆＃39;中的所有步骤进行操作。”由于我有一个现有的应用程序，设置起来并不是那么简单，但我设法解决了大部分问题。现在我得到一个NPE异常，表明CDI无法正常工作。根据{{​​3}}文档，我意识到@PersistenceContext不受支持。这是不幸的，因为那时我可能不能使用Arquillian或者还有其他可能吗？

简化的代码结构：

class MyTest{ 

  @Deployment
  public static EnterpriseArchive createDeployment() {
  ...
  }

  @Inject
  public Service2Inject service;

  @Test
  public void testService() {
    //Assert.assertNotNull("Dependency injection failed!",service);
    String s = service.getSomeString("10");
    ...
  }
}


public class Service2Inject implements SomeInterface {

  @Inject
  private SomeOtherService serviceOther;

  @Override
  public String getSomeString(String id) {
    String testString = serviceOther.getSomeOtherStrings();
    ...
  }
}

public class SomeOtherService implements SomeInterface2 {

  @Inject
  private EntityManager entityManager;

  @Override
  public List<String> getSomeOtherStrings(String Id) {
    Query query = entityManager.createNamedQuery(...)
    ...
  }
}

public class EntityManagerProducer {
   @PersistenceContext(unitName="datasourcename")
   @Produces
   private EntityManager entityManager;
}

那么有可能用Arquillian和WAS远程容器测试我的应用程序吗？

更新：这是堆栈跟踪：

更新：

由于我无法使用简单的JarArchive进行测试，因此我使用以下内容创建一个这样的shrinkwrap Enterprise：

@Deployment
public static EnterpriseArchive createDeployment() {
  EnterpriseArchive ear = ShrinkWrap.create(EnterpriseArchive.class, "application-ear.ear")
  .as(ZipImporter.class)
  .importFrom(new File("../application-ear/target/application-ear-1.0-SNAPSHOT.ear"))
  .as(EnterpriseArchive.class);

  //now add the testClass and any test util classes that are not in the archive
  JavaArchive testLibraryHelper = ShrinkWrap.create(JavaArchive.class)
  .addClass(testClass)
  .addPackage(MiscUtil.class.getPackage())
  .addPackage(some.other.UtilClass.class.getPackage())
  //now for CDI working in testLibraryHelper
  .addAsManifestResource(EmptyAsset.INSTANCE, "beans.xml");
  ear.addAsLibrary(testLibraryHelper);
  return ear;
}

答案 0 :(得分：3)

几条线索：

  1. 确保您可以使用CDI成功运行最简单的测试（因此请删除@PersistenceContext）并创建尽可能小的部署 - 因此请准备一个没有任何依赖关系的CDI bean。
  2. 绝对确保部署的存档启用CDI 。它必须包含beans.xml文件。

    3. 如果你问我，我敢打赌，部署档案没有准备好。这不是你的错，它总是一项复杂，耗时的任务。

    请出于测试目的，将存档类型更改为JavaArchive和 尝试下面的JUnit示例：

    @RunWith(Arquillian.class)
@Category(IntegrationTest.class)
public class AbcIT {

  @Deployment
  public static JavaArchive createDeployment() {
    JavaArchive jar = ShrinkWrap.create(JavaArchive.class)
            .addPackage("com.needed.package")
            .addClass("com.needed.class")
            .addAsManifestResource(EmptyAsset.INSTANCE, "beans.xml"); // CRUCIAL to make CDI work

    System.out.println(jar.toString(true)); // Print to see the content
    return jar;
  }

  @Inject
  private WhateverService service;

  // your test goes here...
}

    稍后，如果上述方法有效，请继续@PersistenceContext，然后检查arquillian-was-remote-8-container-adapter是否支持它（因为您提到的文档来自2014年）。
    如果我是你，我也会试着询问Arquillian的社区。

    希望它有所帮助。
