Modern software projects use issue tracking systems to keep track of software bugs reported by developers and users during the software lifetime. Developers heavily rely on bug reports in issue tracking systems to debug and fix bugs. Once developers receive a bug report, one of the first steps to debugging the issue is to reproduce the reported bug. However, the process of bug reproduction is often manually done by developers, making the resolution of bugs inefficient, especially that bug reports are often written in natural language. In this talk, I present an approach that can automatically reproduce issues from bug reports, targeted at Android apps, to improve the productivity of developers in resolving software bugs. Our approach uses a combination of natural language processing and dynamic GUI exploration to synthesize test scripts with the goal of reproducing the reported bug. We also show that our approach can extract input parameters from bug reports, which can be used to guide test case generation for testing future versions of the software.
