A .NET framework for developing highly-reliable asynchronous software, such as web-services and distributed systems.
P# provides:
- Extensions to the C# language for event-driven asynchronous programming, writing test harnesses, and specifying safety and liveness properties.
- A systematic testing engine that can capture and control all the specified nondeterminism in the system, and systematically explore the actual executable code to discover bugs.
- Get Visual Studio 2015 (required for Microsoft Roslyn).
- Clone this project and compile using VS2015.
Optional: Get the Visual Studio 2015 SDK to be able to compile the P# visual studio extension (syntax highlighting). Only for the high-level P# language.
A good way to start is by reading the manual.
The P# compiler can be used to parse a P# program, rewrite it to C# and finally compile it to an executable. To invoke the compiler use the following command:
.\PSharpCompiler.exe /s:${SOLUTION_PATH}\${SOLUTION_NAME}.sln
Where ${SOLUTION_PATH} is the path to your P# solution and ${SOLUTION_NAME} is the name of your P# solution.
To specify an output path destination use the option /o:${OUTPUT\_PATH}.
To compile only a specific project in the solution use the option /p:${PROJECT_NAME}.
To only compile for testing use the option /t:testing.
The P# tester can be used to systematically test a P# program to find safety property and liveness property violations. It can be invoked on a P# program (dll) that was previously compiled using the P# compiler (or some other custom build system). To invoke the tester use the following command:
.\PSharpTester.exe /test:${DLL_PATH}\${DLL_NAME}.dll
Where ${DLL_PATH} is the path to your P# program and ${DLL_NAME} is the name of your P# program.
You can optionally give the number of testing iterations to perform using /i:value.
To enable liveness checking use the option /liveness.
To see various available command line options for the P# tools use the option /?.
