Welcome from the chairs

It is our great pleasure to welcome you to Riva del Garda (Trento), Italy for the 14^th IEEE International Symposium on Web Systems Evolution (WSE 2012). Since its inception in 1999, the Web Systems Evolution series of events have provided a forum for researchers and practitioners to present original work and discuss issues and new solutions on subjects related to the disciplined evolution of large-scale websites and complex Web applications. This year WSE had a special emphasis on testing - a particularly important and historically under-served area of interest.
