Hibernate 测试EJB&；阿奎利安&；TestNG/野蝇

我正在努力使用Arquillian运行一个相当简单的测试用例——它使用一个EJB类，以便使用JPA（Hibernate）将一个实体（用户）插入数据库，但是抛出了一个异常。我使用TestNG作为测试框架

文件夹结构

MyProject  
   ear
   domain - all jpa entities  
   ejb - holds NewUser ejb  
   war - currently empty

测试

EJB

实体

测试persistence.xml

org.hibernate.jpa.HibernatePersistenceProvider
java:jboss/datasources/examples
business.entities.PersonalData
business.entities.User
符合事实的

无论我做了什么更改，我都会遇到另一个异常…

显然，我有两个test-persistence.xml：一个在域资源中（正确的），另一个在ejb资源中（错误的）。当将域的test-persistence.xml移动到ejb的资源中时，一切都正常了。

为什么要将test-persistence.xml和persistence.xml作为资源添加到存档中？尝试删除persistence.xml。我不会同时添加它们。只是声明test-persistence.xml将作为persistence.xml添加到归档中
