在XUnit中如何对收到的IActionResult进行解析

Question

如何解析在IActionResult测试中收到的IActionResult 。

我已经尝试了以下内容并在行中出现错误（返回null ）

var okObjectResult = actionResult as OkObjectResult;

控制器类

public IActionResult Details(int id)
{
    var pie = _pieRepository.GetPieById(id);

    if(pie==null)
    {
        return NotFound();
    }
    else
    {
        return View(pie);
    }          
}

XUnit测试用例

[Fact]
public async void DetailsTest()
{
    MockPieRepository _data = new MockPieRepository();
    int _id = 1;
    string desc = "Selenium Pie";
    var homecontroller = new HomeController(_data);

    IActionResult actionResult = homecontroller.Details(_id);
    var okObjectResult = actionResult as OkObjectResult;

    Assert.NotNull(okObjectResult);

    var model = okObjectResult.Value as Pie;

    Assert.NotNull(model);         
    Assert.Equal(1, model.Id);
    Assert.Equal(desc, model.ShortDescription);
}

我已经从下面的帖子中引用了代码，但仍然没有运气“ 当IActionResult类型返回结果时如何在Xunit中获取内容值 ”

OkObjectResult通常由API控制器返回。 在您的特定情况下，控制器返回ViewResult类型。

var actionResult = homecontroller.Details(_id);
var viewResult = actionResult as ViewResult;
var actualPie = viewResult.ViewData.Model as Pie;

Assert.NotNull(model);         
Assert.Equal(1, model.Id);
Assert.Equal(desc, model.ShortDescription);
