对于我们的集成测试,我想使用Arquillian并遵循“入门
tutorial”中的所有步骤.由于我有一个现有的应用程序,所以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
WAS 8.5 remote container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,因此我使用以下命令创建一个如下所示的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;
}
解决方法
几条线索：
>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.
>绝对确保部署的存档是启用CDI的.它必须包含beans.xml文件.
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.
请仅出于测试目的,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,请继续使用@PersistenceContext并检查arquillian-was-remote-8-container-adapter现在是否支持它(因为您提到的文档来自2014年).
如果我是你,我也会尝试询问Arquillian的社区.
希望能帮助到你.
