V# benchmarks

This repository contains various built .NET projects used for V# symbolic execution engine performance testing. It is structured as follows: subdirectories in the root directory correspond to different test suites. For each suite there are standalone binaries on which V# can be run.

How to run:

Requirements

• powershell (tested on Windows)
• environment variables VS_BENCH_PATH and VS_PATH set to this repository path and to the V# path respectively
• dotcover global tool installed
• dotnet installed

There is a powershell script cover.ps1 in \runner dir. It has the following parameters

param (
    [Parameter(Mandatory=$true)]$suite, # name of the suite directory (i.e. jb_lifetimes)
    [Parameter(Mandatory=$true)]$dll, # name of the dll file without extension
    $namespace, # name of the namespace to cover
    $class, # name of the type to cover
    $method, # name of the method to cover
    $output, # output directory (default is <script dir>\outputs)
    $searchers = "BFS", # different searchers to run V# with (can be separated with whitespaces)
    $timeouts = "-1", # different timeouts to run V# with (can be separated with whitespaces)
    [switch]$drawCharts = $false, # if true, coverage and statistics charts for diffetent timeouts and searchers are drawn and saved to output
    [switch]$renderTests = $false # if true, tests are also rendered and run
)

If namespace, method and class are not specified, all methods in dll are covered

Example:

.\cover.ps1 -suite jb_lifetimes -dll JetBrains.Lifetimes -namespace JetBrains.Collections -t "20" -renderTests

Test suites:

• jb_lifetimes — https://github.com/JetBrains/rd/tree/master/rd-net/RdFramework and https://github.com/JetBrains/rd/tree/master/rd-net/Lifetimes (.NET Framework). To build (Windows only) use dotnet publish --self-contained -f net461
• loan_exam — a dummy ASP.NET service for credit percent calculation. Target dll is LoanExam.dll. Target method is CreditCalculator.Build. Sources are located in sources/LoanExam. To build (on Windows, for other platforms use a different -r), use dotnet publish -r win10-x64 --self-contained -c Release
• max_arshinov_web — another demo ASP.NET project. Target dll is HightechAngular.Web.dll. Sources: https://github.com/max-arshinov/DotNext-Moscow-2020/tree/step-1 (commit 7ff649b). To build (on Windows, for other platforms use a different -r):
  • Install node.js
  • Replace npm install in https://github.com/max-arshinov/DotNext-Moscow-2020/blob/7ff649bba45cf2b06624eaff00da4e61e46573a1/Apps/HightechAngular.Web/HightechAngular.Web.csproj#L77 with npm install --legacy-peer-deps
  • Run dotnet publish -r win10-x64 --self-contained -c Release
• gsv_gamemaps — algorithms on graphs, matrices etc. Sources can be found in sources/GsvGameMaps
