Question

我正在尝试使用xUnit测试我的控制器，但是在执行Customer Controller时出现以下错误：

“以下构造函数参数没有匹配的灯具数据：CustomerController customerController”

测试课程

public class UnitTest1
{
    CustomerController _customerController;

    public UnitTest1(CustomerController customerController)
    {
        _customerController = customerController;
    }

    [Fact]
    public void PostTestSuccessful()
    {
        Guid guid = Guid.NewGuid();

        CustomerViewModel model = new CustomerViewModel()
        {
            Id = guid,
            Name = "testName",
            Email = "test email",
            PhoneNumber = "test phone",
            Address = "test address",
            City = "test city",
            Gender = "Male"
        };

        var actionResult = _customerController.Post(model);

        Assert.NotNull(actionResult);
        Assert.IsType<Task<IActionResult>>(actionResult);
        Assert.True(actionResult.IsCompletedSuccessfully);
    }

CustomerController类

[Route("customers")]
public class CustomerController : ControllerBase
{
    private readonly ILogger _logger;
    private readonly ICustomerService _customerService;

    public CustomerController(ILogger<CustomerController> logger,
        ICustomerService customerService)
    {
        _logger = logger;
        _customerService = customerService;
    }

    [HttpPost]
    public async Task<IActionResult> Post([FromBody] CustomerViewModel viewModel)
    {
        var customerToBeSaved = viewModel.Adapt<CustomerServiceModel>();

        var customer = await _customerService.SaveAsync(customerToBeSaved);

        var result = customer.Adapt<CustomerViewModel>();

        return Ok(result);
    }

Answer 1

对于测试框架，您需要模拟库以通过DI将模拟对象注入测试类中。您可以使用Nmock，Moq或任何其他模拟库来设置构造函数注入。

Answer 2

如果您不想使用任何模拟框架，只需在构造函数中新建CustomerController。

Answer 3

本文显示了如何使xunit与.Net Core ASP.Net很好地协同工作。它实际上替代了启动，因此您的控制器可以在同一进程中运行，并且可以像在本地一样测试它们。

Answer 4

您缺少的是测试类的 IClassFixture 接口。这将解决问题...

 public class UnitTest1 : IClassFixture<CustomerController>

以下构造函数参数没有匹配的灯具数据
