我是Arquillian的新手，希望獲得一些基本的測試工作（注入一個bean並聲明它執行某些操作）。Arquillian - Weld SE - 獲取NullPointerException
例外：

TestCase類
@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

Assert.assertNotNull(testEntity);
}
}
當我運行它，我得到一個NullPointerException異常，豆經理爲空。它看起來像我缺少一個步驟，但從例子來看，這看起來就是我應該需要的。
任何想法？

很酷，非常感謝，我會給它一個旋轉。 – Walter 2011-05-07 14:27:46
完美，就是這樣。 – Walter 2011-05-09 02:19:15
