public class crumbController: Controller

{

   public ActionResult<IEnumerable<Crumb>> GetBreadcrumb([FromRoute]int tag_X_ParentID)

   {

       try
       {
           Services.Interface.IBreadcrumbService service = new Services.Imp.BreadcrumbService(_configuration, _logger);

           if (service != null)
           {
               Breadcrumb breadcrumb = service.GetBreadcrumb(ParentID);
               return Ok(breadcrumb.crumbs.ToList());
            }
            else
            {
               return BadRequest("Unable to establish connection.");
            }
        }
        catch (Exception ex)
        {
            _logger.LogError(ex.Message, ex);//log error
            return BadRequest(ex.Message);
        }

      }
 }

 public class crumbControllerShould
 {
    [Fact]
    public void GetBreadCrumbsTest()
    {
        IConfiguration _configuration;
        IHostingEnvironment _env;
        ILoggerManager _logger;

        int tag_X_ParentID = 12;


        var mock_logger = new Mock<ILoggerManager>();
        _logger = mock_logger.Object;
        var mock_configuration = new Mock<IConfiguration>();
        _configuration = mock_configuration.Object;

        var mock_env = new Mock<IHostingEnvironment>();

        mock_env
            .Setup(m => m.EnvironmentName)
            .Returns("http://localhost:8980/");

        _env = mock_env.Object;

        Assert.IsAssignableFrom<IHostingEnvironment>(_env);
        Assert.IsAssignableFrom<IConfiguration>(_configuration);
        Assert.IsAssignableFrom<ILoggerManager>(_logger);

        var controller = new BreadcrumbController(_configuration, _env, _logger);
        var result = controller.GetBreadcrumb(tag_X_ParentID);
        Assert.NotNull(result);
        Assert.IsType<IEnumerable<Crumb>>(result);                     
       //this line fails indicating that expected: System.Collections.Generic.IEnumerable'1[[FHH.crumpApi.Entitities.crumb, FHH.BreadcrumbApi]] 

      //Actual: Microsoft.AspNetCore.Mvc.ActionResult'1 [[System.Collections.Generic.IEnumerable'1[[FHH.crubmApi.Entities.crumb,FHH.crumbapi]]
    }
}

;     请查看解释问题的代码中的注释行。
    另外，我需要获取对象才能进行比较Assert.Equal（2，item.tagID）。
    如果我解决问题，将其分配给名为actionResult的变量     然后将其分配给var item = actionResult.firstOrDefault（）以获取item.tagID。     我正在该网站上跟踪以下示例进行IEnumerable单元测试。谢谢您的反馈。

您需要获取ActionResult的模型值才能执行预期的操作。您可以通过将ActionResult转换为ViewResult并获取模型值来实现。有关更多详细信息，请参阅this question的可接受答案。
