Testing D-Bus–based protocols like those used by Telepathy, an IM framework, is hard, and currently requires lots of mock-up code to be written manually. A new language was designed to specify the D-Bus protocols’ state machines, and a tool was written to mock up half of a D-Bus conversation using this language, so as to automatically explore the state space of libfolks or other Telepathy clients. This has enabled more effective fuzz and unit testing of programs which use D-Bus, measured by the lines of code exercised.
