VsixTesting

VsixTesting allows you to easily test your Visual Studio Extensions.

It also supports Visual Studio 2019 / 2022.

Getting Started

The fastest way to get started is cloning the VsixTestingSamples repo and playing with it.

git clone https://github.com/josetr/VsixTestingSamples

Create the test project

TestProject.csproj

<Project Sdk="Microsoft.NET.Sdk">
  <PropertyGroup>
    <TargetFramework>net461</TargetFramework>
  </PropertyGroup>

  <ItemGroup>
    <PackageReference Include="xunit" Version="2.3.1" />
    <PackageReference Include="xunit.runner.visualstudio" Version="2.3.1" />

    <PackageReference Include="VsixTesting.Xunit" Version="0.1.65" /> 

    <!-- Optional package containing shell types used in this sample (VS2017 ~ VS2022) -->    
    <PackageReference Include="Microsoft.VisualStudio.Shell.15.0" Version="15.0.26201" /> 

    <!-- Optional package containing shell types used in this sample (VS2012 ~ VS2019) -->    
    <!-- <PackageReference Include="VSSDK.Shell.11" Version="11.0.4" /> -->

    <!-- Optional project reference to your VSIX Project -->
    <!-- <ProjectReference Include="..\MyVsixProject\MyVsixProject.csproj" /> -->
    <!--
       VsixTesting contains an MSBuild target that scans all project references
       and if they generate a .vsix package, it will copy them 
       to the output folder where the test assembly is located, which
       will cause VsixTesting to install such packages because all packages
       located next to the test assembly are installed by default.
    -->        
  </ItemGroup>
</Project>

TestClass.cs

using Microsoft.VisualStudio.Shell;
using Microsoft.VisualStudio.Shell.Interop;
using Xunit;

namespace Tests
{  
    public class TestClass
    {
        [VsFact]
        void FactTest()
            =>  Assert.NotNull(Package.GetGlobalService(typeof(SVsWebBrowsingService)));

        [VsTheory]
        [InlineData(123)]
        void TheoryTest(int n)
        {
            Assert.NotNull(Package.GetGlobalService(typeof(SVsWebBrowsingService)));
            Assert.Equal(123, n);
        }
    }
}

Configuring how tests run

All the settings are located in ITestSettings and are implemented by 3 attributes:

• [VsTestSettings] for classes/collections/assemblies
• [VsFact] and [VsTheory] for methods

Intellisense should be used to read the documentation for each property that can be set.
