Moq 返回零结果

我正在尝试使用 Moq 来测试 EntityFramework 代码，为什么它在设置后返回零结果。

试图在 workersController 上创建一个无参数的构造函数 - 返回相同的零项

public class WorkerDbTest
{
    private readonly Mock<IWorkerReprisatory> _repo;
    private readonly WorkersController _controller;
    private readonly List<Worker> workers;
    public WorkerDbTest()
    {
        _logger = new Mock<ILogger<WorkersController>>();
        workers = new List<Worker>
        {
            new Worker() {
                Id = 0,
                FirstName = "John",
                MiddleName = "Abraham",
                LastName = "Doe",
                Workplace = "Bomj",
                BirthDate = new DateTime(1700,10,10),
                Employed = new DateTime(1800,10,10)},
            new Worker() {
                Id = 1,
                FirstName = "Alaster",
                MiddleName = "Crowly",
                LastName = "Johns",
                Workplace = "VipBomj",
                BirthDate = new DateTime(1800,12,12),
                Employed = new DateTime(1900,12,12)},
            new Worker() {
                Id = 2,
                FirstName = "Jane",
                MiddleName = "Susan",
                LastName = "Black",
                Workplace = "FemenistBobj",
                BirthDate = new DateTime(2000,11,11),
                Employed = new DateTime(2010,11,11)}
        };
        IQueryable<Worker> workersq = workers.AsQueryable();
        _repo = new Mock<IWorkerReprisatory>();
        _repo.Setup(x => x.GetAll(new WorkerQueryParameters())).Returns(workersq);
    }

    [Fact]
    public void GetOkResult()
    {
        var tst = _repo.Object.GetAll(new WorkerQueryParameters());
    }
}

//Controller class GetAllWorkers
public IActionResult GetAllWorkers(WorkerQueryParameters workerQueryParameters)
    {
        //_logger.LogInformation("GetAllCustomersStarted");
        var allWorkers = _workerRepository.GetAll(workerQueryParameters).ToList();
        var allWorkersDTO = allWorkers.Select(x => Mapper.Map<WorkerDTO>(x));
        if(Response != null)
        {
            Response.Headers.Add("X-Pagination",
            JsonConvert.SerializeObject(new { totalCount = _workerRepository.Count() }));
        }
        return Ok(allWorkersDTO);
    }

当前时间 allWorkers 对象在被调用后产生 0 个条目。所以我想测试我是否有来自 Mock 对象的任何结果，然后得到 var tst 并且仍然没有条目（

假设 GetAll() 应该返回我添加的那三个人作为 iQueryables
