Cannot execute individual tests from ITestDataSource

[elgatov]

Hello,

When trying to execute individual tests created with a ITestDataSource, all the tests execute instead. Why is this happening?

This is the ITestDataSource:

public class TenantDataSourceAttribute : Attribute, ITestDataSource
{
    private readonly string _filePath;

    public TenantDataSourceAttribute(string filePath) => _filePath = filePath;

    [Delimiter(";")]
    [CultureInfo("es-ES")]
    public record Fila
    {
        public string USERNAME { get; set; }
        public string APPNAME { get; set; }
        public string Dominio { get; set; }
    }

    public IEnumerable<object[]> GetData(MethodInfo methodInfo)
    {
        using var reader = new StreamReader(_filePath);
        using var csv = new CsvReader(reader, CsvConfiguration.FromAttributes<Fila>());
        return csv.GetRecords<Fila>().Select(fila => new[] { fila.USERNAME, fila.APPNAME, fila.Dominio }).ToList();
    }

    public string GetDisplayName(MethodInfo methodInfo, object[] data) => $"Tenant: {data[2]}";
}

Packages:

 <ItemGroup>
   <PackageReference Update="Microsoft.NET.Test.Sdk" Version="17.14.1" />
 </ItemGroup>

 <ItemGroup>
   <PackageReference Update="Microsoft.Testing.Extensions.CodeCoverage" Version="17.14.2" />

Thank you. Regards.

After upgrading the following packages they will be reset to previous versions when running tests again:

Fixed it by changing the project header to

<Project Sdk="MSTest.Sdk/3.10.1">

  <PropertyGroup>
    <TargetFramework>net8.0</TargetFramework>
  </PropertyGroup>

</Project>

And reexecuting. Now only one the selected test executes.
