Stateless session bean using JPA for persistence  are most thoroughly testable outside a container without requiring the creation of mock objects

I don't understand this .

It seems to me , this is impossible.  Stateless session bean  can not live outside container ...how come then we test  ? Also Test without creating any objects of the bean !

This is impossible ...is not it ?  Can we really do it ?

It is just an annotated POJO so you don't need container to test.

>>>It is just an annotated POJO
which one ?
Stateful session bean live in EJB container.
>>>so you don't need container to test.
How you are going to test that ?
jakarta Logger will not work unless you deploy .
System.out.println  will not work unless you deploy .
Not sure about Junit / EJB3 Interceptor though

-- which one ?

All EJB 3.0 are POJOs

>>>so you don't need container to test.

-- How you are going to test that ?

Write unit test as you would normally do for POJOs

-- jakarta Logger will not work unless you deploy .

It is not a unit test then since you are not testing your classes in isolation. You should be mocking the logger.

System.out.println  will not work unless you deploy .

-- Incorrect, it will work in any environment.

Yes, normally you would use Asserts. Just usual unit test in which you instantiate your EJB classes as POJOs:

MyBean bean = new MyBeanImpl();

ok..that looks pretty good.

but look   it says   "without requiring the creation of mock objects"  

umm....does it make any sense ?  what this could mean....is it meaningful ?


>>MyBean bean = new MyBeanImpl();

you are really creating instances here  to test.

Can you post the question in full ?

Yes, when you write a unit test, you are supposed to create the object you are testing ?
