Support for keyed services

[ViRuSTriNiTy]

Hi there,

.NET 8 comes with a new feature named keyed services.

Currently, when using this feature in a component tested with Bunit the following exception is thrown:

System.InvalidOperationException : Cannot provide a value for property 'Service' on type 'MyComponent'. The service provider does not implement 'IKeyedServiceProvider' and therefore cannot provide keyed services.

It seems like keyed service support is missing.

Example:

public class MyServiceKey
{
}

public class MyService
{
    public MyService()
    {
    }
}

public class MyComponent : ComponentBase
{
    [Inject(Key = typeof(MyServiceKey))]
    public required MyService Service { get; set; }
}

[Fact]
public void Test()
{
    using var testContext = new TestContext();
    testContext.Services.AddKeyedScoped<MyService>(typeof(MyServiceKey));

    var component = testContext.RenderComponent<MyComponent>();
}

Is it planed to support keyed services or should I go the route of a fallback service provider or even replacing the default service provider?

Hey @ViRuSTriNiTy, thanks for bringing this to our attention.

That's definitely something we need to add support for. If you are up to it, feel free to add support for this by extending https://github.com/bUnit-dev/bUnit/blob/main/src/bunit.core/TestServiceProvider.cs and send in a PR.

There should be a preview package available in a few moments @ViRuSTriNiTy If you have time and gives us feedback whether or not that fits your needs, that would be great. Preview version should be 1.27.11
