最小起订量返回零结果

Question

我正在尝试使用 Moq 来测试 EntityFramework 代码，不知何故 return 设置后结果为零。

尝试在 workersController 上创建无参数构造函数 - 相同的零项 returned

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allWorkers对象在调用后产生0个条目。所以我想测试一下 Mock 对象是否有任何结果然后得到 var tst 并且仍然没有条目（

假设 GetAll() 应该 return 我添加的那三个人作为 iQueryables

Answer 1

您的设置方法匹配 WorkerQueryParameters 的实际对象引用，您需要使用相同的对象引用，或者您需要将给定值与 It.Is<WorkerQueryParameters>(x => x.Value == true) 匹配或者只匹配任何 It.Any<WorkerQueryParameters>()，例如：

    _repo.Setup(x => x.GetAll(It.Any<WorkerQueryParameters>())).Returns(workersq);

可能还值得将您的 mock 设置为 strick，以便它抛出而不是仅仅返回 null 或默认值。

    _repo = new Mock<IWorkerReprisatory>(MockBehavior.Strict);

Answer 2

为什么在启动时添加一个参数并使用它而不是 New WorkerQueryParams() 来达到目的。我仍然不知道为什么，但它工作得很好，并且 returns 3 个条目。感谢所有参与的人和@Nikosi 的想法）

_params= new WorkerQueryParameters()
_repo.Setup(x => x.GetAll(_params)).Returns(workersq);
IQueryable<Worker> tst = _repo.Object.GetAll(_params);
var OkResponse = _controller.GetAllWorkers(_params);
