在非seam-gen生成的Seam项目中运行测试

Question

我有一个项目，首先是使用EJB2编写的，然后迁移到Spring，最后迁移到JBoss Seam 2.2.0 (这就是我正在处理的情况)。它将在Tomcat上运行，但目前它是在JBoss 4.2上执行的(尽管我认为这一事实无关紧要)。我的任务是运行在最后一次迁移之前编写的所有测试。

在谷歌了很多次之后，我写了这样的东西：

public class CustomUserDAOTest extends SeamTest {
    @Test
    public void f() throws Exception {
        new ComponentTest() {
            @Override
            protected void testComponents() throws Exception {
                CustomUserDAO customUserDAO = (CustomUserDAO) Component.getInstance(CustomUserDAOBean.class);
                List<CustomUser> users = customUserDAO.getAll();
                assertNotNull(users);
            }
        }.run();
    }
}

这很好，因为我设法获得了CustomUserDAOBean及其依赖项的实例，但是当我运行测试时，我得到了另一个问题：

我在网上找到了一些关于它的评论，但没有解决方案。我该怎么办？有人有什么想法吗？

提前感谢！

我听从了谢尔文上面的建议，得到了一个解决方案。实际上，当我们使用seam-gen创建一个项目时，src/test目录将包含一个包含以下内容的readme.txt：

If you want to run tests using the Eclipse TestNG plugin, you'll need to add
these jars to the top of your TestNG classpath. Using the Run Dialog, select the
XML suite to run, and select these entries from the project tree:

/lib/test/jboss-embedded-all.jar
/lib/test/hibernate-all.jar
/lib/test/thirdparty-all.jar
/lib/jboss-embedded-api.jar
/lib/jboss-deployers-client-spi.jar
/lib/jboss-deployers-core-spi.jar

You also need to add the Embedded JBoss bootstrap folder, which you can do by
clicking on the Advanced... button.

/bootstrap

Seam uses JBoss Embedded in its unit and integration testing. This has an
additional requirement when using JDK 6. Add the following VM argument to the VM
args tab in the TestNG launch configuration for your suite.

-Dsun.lang.ClassLoader.allowArraySyntax=true 

Please be sure to use JDK 6 Update 4 or better (>= 1.6.0_04) if you are using
JDK 6. The Update 4 release upgraded to JAXB 2.1 which removes a problem with
earlier versions of Sun's JDK 6 which required overriding the JAXB libraries
using the endorsed directory. 

To add tests to your project create a TestNG xml descriptor called *Test.xml
(e.g. FooTest.xml) next to your test classes and run ant test.

我打开了测试的“运行配置”(可以通过工具栏上的“运行”按钮，单击小的黑色向下箭头并选择“运行配置”)，将上面列出的jars添加到“类路径”选项卡中(除了jboss-deployers-client-spi.jar，这是有问题的)，并将-Dsun.lang.ClassLoader.allowArraySyntax=true添加到“参数”选项卡中的"VM参数“中，因为我使用的是Java6。

我仍然有一些问题，但这个具体的问题已经解决了。
