Question

I’m looking for a way to apply TDD to Session Beans.

can anyone provide advices and links on how to unit test them ?

how to use JUnit to do so ?

P.S : I’m new to Test Driven Development and Session Beans.

I’m using EJB v2.

I’m assuming you are talking about EJB2.x Session Beans. For these kind of animals, what I like to do is:

• Use the Session Bean as a wrapper that just delegates logic to a POJO that you can test easily outside a container. Outside container testing is better, faster, easier, etc but won’t cover things such as deployment descriptor validation – and/or –
• Use something like Cactus for in-container testing (check the Howto EJB documentation) – and/or –
• Build and deploy your EJB module with Cargo for integration testing.
