DependencyInjectionDataSourceAttribute and IAsyncInitializer

[Dubzer]

hii
i'm trying to create a DI container with a lifetime of PerClass. and also, my dependencies require database access.

here's what i came up with:

public class TestDependencyInjectionAttribute : DependencyInjectionDataSourceAttribute<IServiceScope>
{
    private IServiceProvider? _serviceProvider;

    [ClassDataSource<DatabaseFixture>(Shared = SharedType.PerClass)]
    public DatabaseFixture Database { get; init; }

    public override IServiceScope CreateScope(DataGeneratorMetadata dataGeneratorMetadata)
    {
        if (_serviceProvider is null)
        {
            var services = new ServiceCollection();
            services
                .AddScoped<DatabaseContext>(_ => Database.CreateContext())

but this code fails because it seems like InitializeAsync was not called for the Database.

is this a bug, and should i even try to do that? i just thought i could inject my dependencies into the test classes using the constructor instead of injecting the service collection

my TUnit version is 1.13 and i'm using .NET 10

Try using IAsyncDiscoveryInitializer instead of IAsyncInitializer.

Data sources are created at discovery time. IAsyncInitializer runs just before a test starts, so you'll need the earlier discovery version instead
