Regression testing has received a significant amount of attention from both academics and practitioners during the last 20 years. Even though the use of regression testing techniques often leads to software applications with high observed quality, the repeated execution of test cases can be so costly that it accounts for half the cost of maintaining a software system. The regression testing research community also faces the additional challenges of transitioning established techniques into practice, improving the status-quo of the empirical evaluation of techniques, and proposing advanced methods for applying regression testing to modern software that is often complex, rapidly evolving, concurrent, and cloud-based. Viewing these tensions and challenges as an opportunity and not a threat, and looking to tap the potential of well-established researchers and up-and-coming members of the community, the theme of this year's workshop is to boldly go where few have gone before. The organizing committee of Regression 2014 invites you to participate in this event by submitting a paper and registering to attend this workshop co-located with ICST 2014.
