Modular programming
Programming code is a specification and architecture for the development and deployment of distributed server side, transactional and secure application components. Application developers focus on programming code business rules and leave the infrastructural service-related issues to the application container and server. Learn about programming side of modular code including modular programming articles, tips and news.

What I want to be able to do is via the HotswappableTargetSource, override the bean definitions of select beans in my application context with my test versions and then run the test. Then, for each test case, I'd like to specify which beans I want to be hot swappable and then each test must be able to create its own mock versions and swap those in, and be able to swap back again."
