测试返回ActionResult <t>的API控制器

Question

测试以下控制器

public class AnnouncementController : Controller
{

    IConfiguration _configuration;

    IHostingEnvironment _env;

    ILoggerManager _logger;

    public AnnouncementController(IConfiguration configuration, IHostingEnvironment env, ILoggerManager logger)
    {
        _configuration = configuration;
        _env = env;
        _logger = logger;
    }

    [HttpGet ("{employeeID}/{moduleID}")]
    public ActionResult<Announcements> GetAnnouncements([FromRoute]int employeeID, [FromRoute] int moduleID)
    {
       try
       { 
          Services.Interface.IAnnouncementService service = new Services.Imp.AnnouncementService(_configuration, _logger);///establishing new Service connection

           if (service != null)
           {
               Announcements announcements = service.GetAnnouncements(employeeID, moduleID);       

               return announcements;
           }
           else
           {
               return BadRequest("Unable to establish connection.");
          }
      }
      catch (Exception ex)
      {
          _logger.LogError(ex.Message, ex);//log error
        return BadRequest(ex.Message);
      }
    }
}

使用以下测试代码：

public void ForSessionActionResult_ReturnsObjectResult()
{
    IConfiguration _configuration;
    IHostingEnvironment _env;
    ILoggerManager _logger;

    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>();
    _env = mock_env.Object;

    var sut = new AnnouncementController(_configuration, _env, _logger);
    int employeeID = 1;
    int moduleID = 1;
    var result = sut.GetAnnouncements(employeeID, moduleID);

    var actionResult = Assert.IsType<ActionResult<Announcements>>(result);
    Assert.IsType<NotFoundObjectResult>(actionResult.Result);

}

我在BadRequestObjectResult上的Assert.IsType NotFoundObjectResult上正在被测试的控制器上。

我不确定是否正确地模拟了控制器构造函数。

但是在上次声明中我得到了BadRequestObjectResult。
