Software projects accumulate large sets of test cases, encoding valuable expert knowledge about the software under test to the extent of many person years. Over time the reliability of the tests decreases, and they become difficult to understand and maintain. Extra effort is required for repairing broken tests and for adapting test suites and models to evolving software systems.

The International Workshop on Validation, Analysis and Evolution of Software Tests (VST) is an unique event bringing together academics, industrial researchers, and practitioners for exchanging experiences, solutions and new ideas in applying methods, techniques and tools from software analysis, evolution and reengineering to advance the state of the art in test development and maintenance.
