Junit, NWDS and NWDI

Hi developers,

I would like to use JUnit to test my NWDS-based developments.

However test files are often deleted from my workspace by NWDS 7.0.

As far as I know Eclipse doesn't usually delete test files... why is this?

Moreover, I would like to version control my unit test on NWDI, should I reference any specific SC in my track/SC for DI build references?

Thanks, regards

Vincenzo
