我是 Arquillian 的新手，想要进行一些基本的测试（注入一个 bean 并断言它做某事）。

例外：

-------------------------------------------------------------------------------
Test set: com.walterjwhite.test.TestCase
-------------------------------------------------------------------------------
Tests run: 1, Failures: 0, Errors: 1, Skipped: 0, Time elapsed: 1.231 sec <<< FAILURE!
test(com.walterjwhite.test.TestCase)  Time elapsed: 0.02 sec  <<< ERROR!

测试用例类

@RunWith(Arquillian.class)
public class TestCase
{
    @Deployment
    public static JavaArchive createDeployment()
    {
        return ShrinkWrap.create(JavaArchive.class).addClasses(TestEntity.class, Implementation.class)
                                         .addAsManifestResource(EmptyAsset.INSTANCE, ArchivePaths.create("beans.xml"));
    }

    @Inject
    Implementation implementation;

    @Test
    public void test() throws Exception
    {
        final TestEntity testEntity = implementation.create();

        Assert.assertNotNull(testEntity);
    }
}

当我运行它时，我得到一个 NullPointerException，bean 管理器为空。看起来我错过了一步，但从示例来看，这似乎就是我所需要的。

有任何想法吗？

在我看来，它正在尝试使用最新的快照。目前 Arquillian 存储库正在重组，因此除非您有特定原因跟踪 HEAD，否则我建议使用 Alpha5。

您可以在 Arquillian 展示中看到有效的 CDI 示例。http://github.com/arquillian/arquillian-showcase

我对 arquillian 1.0.4.Final 也有类似的问题。获取“java.lang.RuntimeException：无法注入成员”加上堆栈跟踪。这是自一年以来运行的测试。如果一个接一个地调用测试类，JUnit 测试可以工作，但如果通过对整个模块进行 Junit 测试或对整个项目进行 maven 站点测试来调用所有测试，则会失败。不管是解决问题，还是将 arquillian 版本重置回 1.0.3.Final！
