使用 Moq for Task<IActionResult> 类型方法的 xUnit 测试

Question

我是 Moq 框架的新手。在这里，我正在尝试为 mvc 项目中的以下方法编写一个简单的 xUnit 测试。在示例代码的最后一部分，我添加了我的 xUnit 测试方法，但我不知道如何设置 commandMock.Setup。知道我应该在上面设置什么吗？

x要写在这个方法上的单元测试：

public async Task<IActionResult> Save(UpdateTermsAndConditionCommand command)
        {
            var response = await Mediator.Send(command);
            return response.Success ? this.SuccessSaveResult(response.Message) : this.FailSaveResult(CommonResources.msgErrorSomthingWentWrong);
        }

UpdateTermsAndConditionCommand class:

public class UpdateTermsAndConditionCommand : IRequest<ResponseDetail>
    {
        public long Id { get; set; }

        [Display(Name = "labelEnglishTermsAndCondition", ResourceType = typeof(TermsAndConditionResources))]
        [XSSIgnore]
        [Required(ErrorMessageResourceName = "msgEnglishTermsConditionRequire", ErrorMessageResourceType = typeof(TermsAndConditionResources))]
        public string EngTermsAndCondition { get; set; }

        [Display(Name = "labelDutchTermsAndCondition", ResourceType = typeof(TermsAndConditionResources))]
        [XSSIgnore]
        [Required(ErrorMessageResourceName = "msgDutchTermsConditionRequire", ErrorMessageResourceType = typeof(TermsAndConditionResources))]
        public string DutchTermsAndCondition { get; set; }

        [Display(Name = "labelGermanTermsAndCondition", ResourceType = typeof(TermsAndConditionResources))]
        [XSSIgnore]
        [Required(ErrorMessageResourceName = "msgGermanTermsConditionRequire", ErrorMessageResourceType = typeof(TermsAndConditionResources))]
        public string GermanTermsAndCondition { get; set; }
    }

调解员class:

[XSSFilter]
    public abstract class BaseController<T> : Controller
    {
        private ISender _mediator;
        
        private ILogger<T> _logger;
        protected ISender Mediator => _mediator ??= HttpContext.RequestServices.GetService<ISender>();
        protected ILogger<T> Logger => _logger ??= HttpContext.RequestServices.GetService<ILogger<T>>();
        
        [HttpPost]
        public ActionResult Pdf_Export_Save(string contentType, string base64, string fileName)
        {
            var fileContents = Convert.FromBase64String(base64);

            return File(fileContents, contentType, fileName);
        }
        
        public async Task<List<LanguageListItemDto>> GetLanguages()
        {
            var response = await Mediator.Send(new GetLanguageListQuery());
            return response.Languages;
        }
    }

xUnit 测试使用最小起订量：

  [Fact]
        public void SaveXUnit()
        {

            //arrange
            var commandMock = new Mock<UpdateTermsAndConditionCommand>();
            var controller = new TermsandConditionController();
            commandMock.Setup(x => x.Execute());//here i am not getting idea how to setup the command

            //act

            //assert

        }

Answer 1

UpdateTermsAndConditionCommand 是一个 class，您可以实例化它 (var command = new UpdateTermsAndConditionCommand { })，不能被模拟。

只能模拟 abstract classes 和 interfaces。

最简单的方法是在您想要测试和模拟的class 中注入 依赖项。您可以先阅读 Dependency Injection
