Mocking derived class with abstract base class

Hi, I have the following setup: 
**BASE CLASS**
public abstract class SomeBaseAbstractClass<TItem, TResponse>
{
  protected EctocloudCosmosRepository(IMapper mapper, IRepository<TItem> repository, ILogger logger)
  {
      _mapper = mapper;
      _repository = repository;
      _logger = logger;
   }

    public async Task<TResponse> GetAsync(string id, CancellationToken token)
    {
      // some logic removed for brevity
    }
}

**IMPLEMENTED CLASS**
public class Repository : SomeBaseAbstractClass<Item, Response>
{
   // ctor
   // methods
}

**CONTROLLER**
public async Task<ActionResult> GetSomeStuff(
            [FromRoute] string id,
            [FromServices] Repository repository)
        {
            var response = await repository.GetAsync(id, HttpContext.RequestAborted);
            return HandleResponse(response);
        }
**BASE CLASS**
public abstract class SomeBaseAbstractClass<TItem, TResponse>
{
  protected EctocloudCosmosRepository(IMapper mapper, IRepository<TItem> repository, ILogger logger)
  {
      _mapper = mapper;
      _repository = repository;
      _logger = logger;
   }

    public async Task<TResponse> GetAsync(string id, CancellationToken token)
    {
      // some logic removed for brevity
    }
}

**IMPLEMENTED CLASS**
public class Repository : SomeBaseAbstractClass<Item, Response>
{
   // ctor
   // methods
}

**CONTROLLER**
public async Task<ActionResult> GetSomeStuff(
            [FromRoute] string id,
            [FromServices] Repository repository)
        {
            var response = await repository.GetAsync(id, HttpContext.RequestAborted);
            return HandleResponse(response);
        }
Now I would like to unit test GetSomeStuff, and ensuring correct HTTP status codes are returned based on response from .GetAsync() method. How would I unit test this?

that wouldn't be a unit test afaik, that's technically an end-to-end test. or implementation test

I would of course mock away all dependencies. I would only like to ensure that depending on what the answer is from 
 await repository.GetAsync(...) 
 await repository.GetAsync(...)
the correct HTTP response is returned.
