GnomeStack.Xunit.Core

Provides dependency injection for Xunit test class constructors and test methods that use attributes from GnomeStack.Xunit.Attributes.

To enable DI, the Xunit.GnomeStackTestFramework must be added to your test assembly so that Xunit knows which test framework is responsible for test execution.

The attribute may be added through a csproj file using the following:

<ItemGroup>
    <AssemblyAttribute Include="Xunit.GnomeStackTestFramework" />
</ItemGroup>

The package comes with its own simple dependency injector that wires up an IAssert instance and ITestOutputHelper. The benefits of using IAssert is adding extension methods.

[UnitTest]
public void Verify_TestDependencyInjection_ForTestOutputHelper(
    IAssert assert, 
    ITestOutputHelper writer)
{
        writer.WriteLine("Console output!");
        const int h = 0, i = 18;
        assert.NotEqual(h, i);
}

A test class or a test case may use the UseServiceProviderFactoryAttribute to replace the built in simple dependency injector with its own implementation. The attribute requires an type that implements ITestServiceProviderFactory and it must return an object that implements IServiceProvider.

internal class DIFactoryA : ITestServiceProviderFactory
{
    public IServiceProvider CreateServiceProvider()
    {
        // SimpleServiceProvider auto adds IAssert and ITestOutputHelper
        var services = new SimpleServiceProvider();
        services.AddTransient(typeof(ICustomService), _ => new MyCustomService());

        return services;
    }
}

public class MyTest
{
    [UnitTest]
    [UseServiceProviderFactory(typeof(DIFactoryA))]
    public void Verify_TestDependencyInjection_CustomFactory(
        IAssert assert, 
        ICustomService myService)
    {
        assert.NotNull(myService);
        assert.Equal("My", myService.Name);
    }
}

These ideas are not new and come from other existing projects like Xunit Skippable Fact & dotnet arcade. Huge shoutout to Xunit for enabling extension points.
