Java AppEngine Jersey Junit测试不工作（未为此线程注册api）

我真的很难让泽西、阿彭金和朱尼特工作。当前错误如下：

java.lang.NullPointerException: No API environment is registered for this thread.

• 在注释之前通过JUnit@加载helper.setUp（）（LocalDataStoreService）

• 在JUnit@Before注释上创建Grizzly Web服务器的实例

• 执行testCreateCard测试

• 停止Grizzly Web服务器

• 在JUnit@After注释上运行helper.tearDown（）方法

我使用EclipseIndigo启动（以运行方式）Junit测试（我在Java构建路径中包括JAR）

Jersey或Grizzly Webcontainer似乎正在打开与本地数据存储方法helper.setUp（）和helper.tearDown（）不兼容的新线程

我发现了一些问题/答案，但与使用AppEngine搭配Jersey无关

有人能帮忙吗？Jersey、AppEngine和JUnit真的可以安装吗？我使用rest assured和jersey测试框架尝试了几种可能性，但所有尝试都以错误和调试告终，并且在AppEngine邮件列表中发布了一篇文章，但没有任何结果

我最后的希望是我目前的设置：

• Grizzly 2.1（由泽西提供）

• 泽西1.12

• JUnit4.10

如果你用的是appengine，为什么要用grizzly？阿彭金是你的容器，不是灰熊。

谢谢你把我带到这条路上，瑞克。是的，使用AppEngine作为容器会很好。但是如何在注释前后通过JUnit启动整个web框架呢？当我运行JUnit时，我希望我的环境开始进行测试，然后再次关闭。Google文档只提到通过命令行启动它。我刚刚读到Jetty也将产生新的流程。如何将web服务器限制为只生成一个进程？您不能为单元测试启动web容器。这就是appengine测试线束的用途。您应该以编程方式测试jersey服务，而不是通过向它们发送请求。换句话说，不要使用jersey客户机类来发送请求，而是直接在服务类上调用方法。如果你启动一个容器，那不是一个单元测试。。。这是一个集成测试，我明白了。我会尽力的，谢谢。但即便如此，似乎仍有许多人使用JUnit进行集成测试。所以我猜他们是在“虐待”JUnit？那么我该如何进行集成测试呢？只需编写一个客户机并在启动后连接到服务器？没有滥用，它是一个可以做任何事情的工具。但在本例中，这是错误的，因为您正在启动appengine模拟数据存储和非appengine容器，而这是行不通的。是的，要使用appengine进行集成测试，最好的方法是从命令行启动开发服务器，然后编写脚本来启动它。
