在不是由 seam-gen 生成的 Seam 项目中运行测试

Question

我有一个项目首先使用 EJB 2 编写，然后迁移到 Spring，最后迁移到 JBoss Seam 2.2.0（这是我正在处理的情况）。它将在 Tomcat 上运行，但现在它在 JBoss 4.2 上执行（尽管我相信这个事实无关紧要）。我的任务是运行上次迁移之前编写的所有测试。

经过大量的谷歌搜索，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 的实例及其依赖项，但是当我运行测试时，我遇到了另一个问题：

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

提前致谢！

我已经按照上面 Shervin 的建议得到了解决方案。实际上，当我们使用 seam-gen 创建项目时，src/test 目录将包含一个 readme.txt，其内容如下：

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，点击黑色的小向下箭头并选择“运行配置”），添加上面列出的jar “类路径”选项卡（jboss-deployers-client-spi.jar 除外，这是有问题的）并在“参数”选项卡的“VM 参数”中添加了-Dsun.lang.ClassLoader.allowArraySyntax=true，因为我使用的是 Java 6。

我还有一些问题，但是这个特定的问题已经解决了。
