Spring was probably born as a reaction to EJB. And if you've ever written tests for EJBs you're grateful to Spring for providing an alternative.

I've written UnitTests for EJBs today. No Spring bloatware needed.

Well what version of JEE are you using? Compare that to writing unit tests for the version of JEE that existed when Spring was created. A lot of what makes EJBs easier to test today is because of influence by dependency injection frameworks (like Spring) from yesterday.
