Title: Recent Research on Search Based Software Testing Abstract: Software Testing is an important and time-consuming task in the Software Development Lifecycle whose goal is to detect faults in the software product or certify that it fulfills the specification with a high confidence. A software fault discovered after the product have been released entails great economic losses for a software company. For this reason Industry, and also Academia, are interested in automatic tools that assist software testers in their task, saving time and resources at the same time that the quality of the product increases. Many of the problems that arise in Software Testing can be formulated as optimization problems that can be solved using search techniques. This domain of research is called Search Based Software Testing (SBST). In this talk the speaker will present some recent advances in this domain. In particular, he will focus on their recent research in the test suite minimization problem, the prioritized pairwise test case generation, the testing of software product lines and a novel proposal to measure the cost of testing a program.
