Only 26% felt there was an existing framework that could do the job, and 42% of those mentioned Spring MVC.
Agile software development teams have to assure that the products that they develop have sufficient quality.

Several authors have written about velocity and shared their concerns on measuring velocity to improve the productivity of teams.
When defining a business case for adopting agile, the question can arise how you can measure the business value that can be delivered using agile software development.

Brett Slatkin from Google presented a method for visual regression testing at Velocity 2013 in Santa Clara. Perceptual diff compares screenshots of a release's webpages with its previous versions and detects changes at pixel level, filling an important gap in automated testing for Continuous Deployment. An open source version of the software has been setup on github.
Struts 1, the venerable Java MVC Web framework, has reached End Of Life status, the Apache foundation has announced. In a sense, the move simply formalises what has already happened, as the Struts team have focused their efforts on version 2; the last release of Struts 1 was in December 2008. The change of status does mean that no further security patches or bug fixes will be issued.
