Question

我正在尝试从对控制器的调用中检查HttpStatusCode，但是我不知道如何将我的ActionResult<T>转换为HttpStatusCodeResult。

控制器的方法：

[Get]
public async Task<ActionResult<PagedResult<PersoDemandLiteResponse>>> GetDemandsByFilterAsync([FromQuery] DemandFilterRequest filter)
    => await this.GetAsync(() => DemandService.GetDemandByFilterAsync(filter), (sources) => sources);

这是我的测试方法（简化）：

... mocking of the services ...

var controller = new DemandController(demandService, organizationService.Object, productService.Object, Mapper.Object);

var request = new DemandFilterRequest { OrganizationId = Guid.NewGuid() };

var result = await controller.GetDemandsByFilterAsync(request);

//I would like to do something like this 
 var action = result as HttpStatusCodeResult;
 var badRequest = (int)HttpStatusCode.BadRequest;

 Assert.Equal(badRequest, action.StatusCode);

但是出现以下错误：

错误CS0039无法通过引用转换，装箱转换，拆箱转换，换行转换或空类型转换将类型“ Microsoft.AspNetCore.Mvc.ActionResult>”转换为“ System.Web.Mvc.HttpStatusCodeResult”。

关于如何实现此目标的任何想法？

假设示例代码暗示测试中的方法返回了错误的请求，那将类似于

//...

if(...)
    return BadRequest();

//...

然后在进行单元测试时，需要从操作结果中提取包装的结果

//Arrange
//...omitted for brevity

//Act
ActionResult<PagedResult<PersoDemandLiteResponse>> response = 
    await controller.GetDemandsByFilterAsync(request);

//Assert
var actual = response.Result as BadRequestResult;    
Assert.NotNull(actual);

引用Controller action return types in ASP.NET Core Web API

单元测试AspNetCore控制器使用ActionResult <T>结果检查HttpStatusCode
