Arquillian 混合模式不适用于 TestNG

Question

我正在尝试使用 Arquillian 和 TestNG 以混合模式运行测试套件。

基于此处的文档：http://arquillian.org/arquillian-core/#mixed-mode

我希望能够像这样编写我的测试：

public class ExampleTest extends Arquillian {
    
    @Deployment
    public static EnterpriseArchive createDeployment() {
      return ear; //contains both web and jar modules
    }
    
    @Test @RunAsClient
    public void testA(@ArquillianResource(TestServlet.class) URL baseUrl) {
        runTest(baseURL);
    }

    @EJB //Used for container tests
    public TestBean bean;
    
    @Test 
    public void testB() throws Throwable {
        bean.runTest();
    }
}

在这种情况下，testA 失败，因为 TestNG 不允许测试方法具有注入参数。

如果相反，我将测试 URL 作为这样的字段注入：

public class ExampleTest extends Arquillian {

    @Deployment
    public static EnterpriseArchive createDeployment() {
      return ear; //contains both web and jar modules
    }
    
    @ArquillianResource(TestServlet.class) //Used for client tests
    URL baseUrl

    @Test @RunAsClient
    public void testA() {
        runTest(baseURL);
    }

    @EJB //Used for container tests
    public TestBean bean;

    @Test 
    public void testB() throws Throwable {
        bean.runTest();
    }
}

那么testB 将失败，因为它无法注入 URL 字段，即使它没有被注释为客户端测试：

TestNG 不支持混合模式还是我做错了什么？

感谢您的帮助！

来自文档Arquillian documentation - Mixed Mode：

不同运行模式的效果取决于所使用的 DeployableContainer。这两种模式在某些嵌入式容器中的行为似乎相同，但您应该避免混合内部和外部测试。一件事是他们应该测试你的应用程序的不同方面和不同的用例，另一件事是你会错过切换 DeployableContainers 的好处，如果你这样做的话，你会在远程服务器上运行相同的测试套件。

也许这就是问题所在，您的 EAR 混合了上下文。如果可能的话，您可能不得不使用 WAR。

愚蠢的问题，这可能会奏效，您是否尝试强制测试顺序？将 as-client 作为最后一个测试用例运行可能会解决您的问题。
