Uno Unit Tests on Linux

[HowardPWeiss]

Are Unit Tests supported on Linux?

Hello @HowardPWeiss,

Unit tests on Linux with the Uno Platform work the same as in .NET, as Uno supports cross-platform .NET development. You can use dotnet test to run tests on Linux, just like you would on Windows or macOS.

Let me know if you need specifics about your setup or further help

As I mentioned in my second point, you don’t need to create a new project. You can define the package version in your central package management file, Directory.Packages.props, and reference it in the .csproj file.

In your Directory.Packages.props add a PackageVersion reference to MSTest and other packages you use:

<ItemGroup>
 <PackageVersion Include="MSTest" Version="3.6.1" />
 ...
</ItemGroup>

And in your Unit Test project .csproj, reference the packages without specifying the versions:

<ItemGroup>
 <PackageReference Include="MSTest.TestFramework" />
 ...
</ItemGroup>

Let me know if this helps!

Martin -

I am still not understanding. Your use "you don't need to a create a new project" could mean one of two things

1. I do not need to create a new solution with both a project and a test project and migrate my existing code to the new project
2. I do not need a add a test project to my current solution test project

I assume that you mean the first.. In other words, I need to add a unit test project to my existing solution using the solution explorer. To date, I have been adding an "MSTest Test Project" to my existing solution.

This generates the attached csproj file
Hello.UnitTests.csproj.txt

As soon as I do this, I see the message "Failed to restore NuGet packages for the solution"

I notice that the Directory.Packages.Props file in the original project is empty
Directory.Packages.props.for.Original>project.txt

I then right click on the UnitTest project in the solution explorer and then click rebuild

This produces the following messages in the terminal window
Rebuild_Unit_Test_Project.txt

with the error "Projects that use central package version management should not define the version on the PackageReference items but on the PackageVersion items.

My understanding is that the edits you suggest are to fix this error

Yes?

I edited the Directory.Packages.Props and .csproj per your instructions

Rebuid now produces an error

Rebuild_Unit_Test_Project_edited.txt

If I change "PackageReference Include="MSTest.TestFramework" to PackageReference Include="MSTest" , the test project builds and executes

⚠️ If you use the meta package MSTest, you shouldn't need to use MSTest.TestFramework or MSTest.TestAdapter at all ⚠️
