在 C# 集成测试中查询 JsonResult

Question

我正在尝试为 MVC 应用程序编写一些集成测试，如下所示

控制器

public JsonResult CreateWithJson(List<string> values) 
{
  if (values == null) return Json(new { Valid = false, Message = "No data was received by the server" });
}

测试类

public static void TestEmptyDataFailsGracefully()
{
  var objUt = new MyController();
  var actual = objUt.CreateWithJson(new List<string>());

  actual.Should().BeOfType(typeof(JsonResult));

  // this is System.Object
  actual.Data...

  // what I want to do
  actual.Data.Valid.Should.Be(false);
}

请问JsonResult中返回的匿名类型如何查询呢？

您需要定义要反序列化的类型 JsonResult。

public class ValidationResults 
{
   bool Valid {get;set;}
   string Message {get;set;}
}

public JsonResult CreateWithJson(List<string> values) 
{
  if (values == null) return Json(new ValidationResults { Valid = false, Message = "No data was received by the server" });
}

public static void TestEmptyDataFailsGracefully()
{
  var objUt = new MyController();
  var actual = objUt.CreateWithJson(new List<string>());

  actual.Should().BeOfType(typeof(JsonResult));

  var serializer = new JavaScriptSerializer();
  var json = serializer.Serialize(actual.Data);
  ValidationResults validationResult = serializer.Deserialize<ValidationResults>(json);


  // what I want to do
  validationResult .Valid.Should.Be(false);
}
