Question

我正在尝试使用CDI-Unit来测试我的Wicket组件，它们使用CDI进行依赖注入。测试似乎在Eclipse中完美运行但在我的Maven构建期间失败，我似乎无法找到任何提示和错误。

我创建了一个简单的抽象WicketPanel

public abstract class MyPanel extends Panel{

  private static final long serialVersionUID = 4132041261965905788L;

  private final RepeatingView rw;

  @Inject 
  transient ReflectiveComponentFactory factory;

  public MyPanel(String id) {
    super(id);
    rw = new RepeatingView(OVERLAY_COMPONENT_GROUP_ID);
    add(rw);
  }

  @Override
  public <CT extends Component> CT addComponent(Class<CT> componentType) {
    return addComponent(componentType, OVERLAY_COMPONENT_ID);
  }

  protected <CT extends Component> CT addComponent(Class<CT> componentType, String overlayComponentId) {
    WebMarkupContainer collapsableGroup = new WebMarkupContainer(rw.newChildId());
    rw.add(collapsableGroup);

    CT component = factory.createComponent(componentType, overlayComponentId);
    collapsableGroup.add(component);

    return component;
  }
}

注射工厂：

@ApplicationScoped
public class ReflectiveComponentFactory implements Serializable{
  private static final long serialVersionUID = -4587243549845349456L;

  public <CT extends Component> CT  createComponent(Class<CT> componentType, String componentId){
    try {
      Constructor<CT> constructor = componentType.getConstructor(String.class);
      return constructor.newInstance(componentId);
    } catch (ReflectiveOperationException | SecurityException | IllegalArgumentException e) {
      throw new ComponentCreationException(e);
    } 
  } 
}

然后使用CDI-Unit创建单元测试：

@RunWith(CdiRunner.class)
@AdditionalClasses(value={ReflectiveComponentFactory.class})
public class MyPanelTest {
  private WicketTester tester;

  @Inject
  private BeanManager beanManager;

  @Before
  public void setup() {
    tester = new WicketTester();
    new CdiConfiguration(beanManager).setPropagation(ConversationPropagation.NONE).configure(tester.getApplication());
  }

  @Test
  public void testAddComponentWithClass() {
    MyPanelTested myPanel = new MyPanelTested("someId");
    TestPanel panel1 = myPanel.addComponent(TestPanel.class);
    TestPanel panel2 = myPanel.addComponent(TestPanel.class);

    tester.startComponentInPage(myPanel);
    tester.assertComponent(panel1.getPageRelativePath(), TestPanel.class);
    tester.assertComponent(panel2.getPageRelativePath(), TestPanel.class);
    tester.assertComponent(panel1.getPageRelativePath() + ":text", Label.class);
    tester.assertComponent(panel2.getPageRelativePath() + ":text", Label.class);
  }
}

@SuppressWarnings("serial")
class MyPanelTested extends MyPanel {
  public MyPanelTested(String id) {
    super(id);
  }
}

我没有包含TestPanel，但它非常简单（并且或多或少是空的）。

当我在Eclipse中执行此操作时，测试通过绿色！

当我用Maven执行此操作时，我得到以下内容：

org.jboss.weld.context.ContextNotActiveException: WELD-001303 No active contexts for scope type javax.enterprise.context.Dependent

  .....

我做错了什么线索？

问题是由cdi-unit版本2.0.8中的错误引起的。 Bryn解决了这个问题（参见https://github.com/BrynCooke/cdi-unit/issues/21），因此如果使用cdi-unit 2.0.9或更高版本，它就不会出现。

WicketTester和CDI-Unit的单元测试在Eclipse中工作，但在Maven构建期间失败。我错过了什么？
