如何在ASP.NET MVC测试时访问JsonResult数据 [英] How to access JsonResult data when testing in ASP.NET MVC

问题描述

我在C＃MVC控制器这个code：

I have this code in C# mvc Controller:

[HttpPost]
    public ActionResult Delete(string runId)
    {
        if (runId == "" || runId == null)
        {
            return this.Json(new { error = "Null or empty params" });
        }
        try
        {
            int userId = (int)Session["UserId"];
            int run = Convert.ToInt32(runId);

            CloudMgr cloud = new CloudMgr(Session);
            cloud.DeleteRun(userId, run);

            return this.Json(new { success = true });
        }
        catch (Exception ex)
        {
            return this.Json(new { error = ex.ToString() });
        }
    }

我如何访问我的JSON的错误字段中ControllerTest来检查它是否是空或不是？

How I can access my Json "error" field in a ControllerTest to check if it is null or not?

[TestMethod]
    public void DeleteWrongParam()
    {
        WhatIfController controller = new WhatIfController();
        controller.ControllerContext = 
        TestUtils.CreateMockSessionControllerContext().Object as ControllerContext;

        JsonResult result = controller.DeleteWhatIf(null) as JsonResult;

Assert.IsNotNull（result.Data.error）; 是我想做些什么。有任何想法吗？谢谢你。

Assert.IsNotNull(result.Data.error); is what I would like to do. Any Ideas? Thanks.

推荐答案

您可以使用这样，结果将有望对象定义。所以，如果OD的成功，你的成功标志是TRUE否则为false，如果假的，那么你应该预料到的错误属性与错误信息进行更新。

you can use like this , Result will be expected object definition . So in case od success , your success flag will be TRUE otherwise false and if false then you should expect that error property is updated with the error message.

        JsonResult jsonResult = oemController.List() as JsonResult;
        JavaScriptSerializer serializer = new JavaScriptSerializer();
        Result result = serializer.Deserialize<Result>(serializer.Serialize(jsonResult.Data));

        public class Result 
        {
            public bool success ;
            public string error;
        }
