Microsoft Fakes

This feature requires the Microsoft.Testing.Extensions.Fakes NuGet package.

Tip

When using Microsoft.Testing.Platform.MSBuild (included transitively by MSTest, NUnit, and xUnit runners), this extension is auto-registered when you install its NuGet package — no code changes needed.

The Microsoft.Testing.Extensions.Fakes extension provides support to execute a test project that makes use of Microsoft Fakes.

Microsoft Fakes allows you to better test your code by either generating Stubs (for instance creating a testable implementation of INotifyPropertyChanged) or by Shiming methods and static methods (replacing the implementation of File.Open with a one you can control in your tests).

Note

This extension requires a Visual Studio Enterprise installation with the minimum version of 17.11 preview 1 in order to work correctly.

Upgrade your project to the new extension

To use the new extension with an existing project, update the existing Microsoft.QualityTools.Testing.Fakes reference with Microsoft.Testing.Extensions.Fakes.

- <Reference Include="Microsoft.QualityTools.Testing.Fakes, Version=12.0.0.0, Culture=Neutral">
-   <SpecificVersion>False</SpecificVersion>
- </Reference>
+ <PackageReference Include="Microsoft.Testing.Extensions.Fakes" Version="17.12.0" />

If you are using MSTest.Sdk 3.7 or later, use the EnableMicrosoftTestingExtensionsFakes property to enable the extension and don't add the package reference.
