A toolkit for building, analyzing, systematically testing and debugging asynchronous reactive software, such as web-services and distributed systems.
The P# framework provides:
- Language extensions to C# for building event-driven asynchronous applications, writing test harnesses, and specifying safety and liveness properties.
- A systematic testing engine that can capture and control all specified nondeterminism in the system, systematically explore the actual executable code to discover bugs, and report bug traces. A P# bug trace provides a global order of all communication events, and thus is easier to debug.
- Support for replaying bug traces, and debugging them using the Visual Studio debugger.
Although P# primarily targets .NET, it has also experimental support for systematically testing native C++ code.
The best way to build and start using P# is to read our wiki.
