Add Unit Tests to a .NET MAUI Application

• Jan 18, 2024

You can create unit test for .NET MAUI applications that contain DevExpress .NET MAUI Controls in any of the following ways:

• Move ViewModels, Services, and other modules into a separate assembly and then test this assembly.

• Add the net8.0 to target versions of your project and then test this assembly. To do this, perform the following steps:

  1. Add the net8.0 to target frameworks in your app’s project file:

     DXMauiApp.csproj

     <Project Sdk="Microsoft.NET.Sdk">
         <PropertyGroup>
             <TargetFrameworks>net8.0;net8.0-android;net8.0-ios</TargetFrameworks>
             <OutputType Condition="'$(TargetFramework)' != 'net8.0'">Exe</OutputType>
             <!-- ... -->
         </PropertyGroup>
         <!-- ... -->
     </Project>
     

  2. Build your project for the net8.0 framework.

  3. Create a project and add your unit tests.

  4. Reference your .NET MAUI application in the unit test’s project:

     UnitTests.csproj

     <Project Sdk="Microsoft.NET.Sdk">
         <PropertyGroup>
             <TargetFramework>net8.0</TargetFramework>
             <!-- ... -->
         </PropertyGroup>
         <ItemGroup>
             <PackageReference Include="xunit" Version="2.6.4" />
             <PackageReference Include="Microsoft.NET.Test.Sdk" Version="17.8.0" />
             <PackageReference Include="xunit.runner.visualstudio" Version="2.5.6">
                 <IncludeAssets>runtime; build; native; contentfiles; analyzers; buildtransitive</IncludeAssets>
                 <PrivateAssets>all</PrivateAssets>
             </PackageReference>
         </ItemGroup>
         <ItemGroup>
             <ProjectReference Include="..\DXMauiApp\DXMauiApp.csproj" />
         </ItemGroup>
     </Project>
