Go2Pins: A framework for the LTL verification of Go programs (extended version)


We introduce Go2Pins, a tool that takes a program written in Go and links it with two model-checkers: LTSMin and Spot. Go2Pins is an effort to promote the integration of both formal verification and testing inside industrial-size projects. With this goal in mind, we introduce black-box transitions, an efficient and scalable technique for handling the Go runtime. This approach, inspired by hardware verification techniques, allows easy, automatic and efficient abstractions. Go2Pins also handles basic concurrent programs through the use of a dedicated scheduler. Moreover, in order to efficiently handle recursive programs, we introduce PSLRec, a formalism that augments PSL without changing the complexity of the underlying verification process.
