I am not sure what you are referring to as light weight frameworks. But we cover, JUnit, Cactus and DBUnit.

Yup I think the author mentioned that Spring was not around (not so prevalent) when they were writing thebook. Spring , nanocontainer, pico container etc might find a place in the 2nd edition.
Sorry, I missed the word framework following light. See the What's missing thread to see what Brian and I would like to include in a second edition or second volumne if we get the chance. Spring and light weight containers would definatly be included.
