ABAP Unit Test Classes - Good References

Question

I'm looking for good reference material regarding the use of ABAP Unit Test Classes.

I'm interested in any of the following:

• Documentation on the functionality
• Best Practises
• "How To Guides"
• Blogs/Books on people's experience in using test-driven development in a SAP environment, particularly what sort of scenarios leans themselves to test-driven development & how you get around the dependency of SAP on business data.

Answer 1

There is some documentation in sap.com.

Also, there is a German PDF (see here) that may be helpful if you know some German ;-) At least it contains a few email addresses of people that may be able to help. Not sure because the PDF is from a conference in 2003, so the contact info may not be too up to date.

Lastly. there seems to be a German book (on Amazon Germany) .. again not sure if that helps you.
