Another area where I feel Spring can add more is in Test Driven Development. Lots of stuffs are going on to make tests more expressive or literate, so that they read more like specifications. Have a look at LiFT and the integration of TestNG and Abbott, where Alex Ruiz is doing some really good work on giving tests a real facelift. And, with scripting languages like Groovy and JRuby very much a part of the JVM support, this should not be very difficult. Groovy categories and Higher Order Messaging hold some interesting promise in having more literate testing abstractions within Spring.
Did you ever raise these improvements Debasish?
