使用最小起订量进行单元测试

Question

这是我控制器下的一种方法，用于创建虚拟密钥来加密应用程序中的数据并将其存储在 amazon s3 存储桶中。

public JsonResult SaveMasterKeys(string MekText, int Thismek)
        {
            string folderName = string.Empty, fileName = string.Empty;
            List<string> folderNameList = new List<string>();
            folderNameList.Add("Guard1");
            folderNameList.Add("Guard2");
            try
            {
                if (Thismek == 1)
                {
                    folderName = "Guard1";
                    fileName = "NewMek1.key";
                }
                else
                {
                    folderName = "Guard2";
                    fileName = "NewMek2.key";
                }
                AWSS3File aws = new AWSS3File();

                //aws.BucketExist(filePath);
                //aws.CreateFile(MekText, filePath);
                // Check Weather the Folder is exist or not

                if (!aws.CheckFolderExist(folderName))
                {
                    foreach (var item in folderNameList)
                    {
                        aws.CreateFolder(item);
                        if (item == "Guard1")
                        {
                            aws.CreateFileIntoS3((item == folderName ? MekText : ""), item, "NewMek1.key");
                            aws.CreateFileIntoS3("", item, "Mek1.key");
                        }
                        else
                        {
                            aws.CreateFileIntoS3((item == folderName ? MekText : ""), item, "NewMek2.key");
                            aws.CreateFileIntoS3("", item, "Mek2.key");
                        }
                    }
                }
                else
                {
                    aws.CreateFileIntoS3(MekText, folderName, fileName);
                }
                ViewData["SaveMessage"] = "Saved successfully.";
            }
            catch (Exception ex)
            {
                XTP.Logger.LogCritical("XTP.Web.internaltools", ex.ToString());
                ViewData["SaveMessage"] = "Keys not updated successfully.";
            }
            return Json(new { success = true, value = ViewData["SaveMessage"] }, JsonRequestBehavior.AllowGet);
        }

这是我为此编写的测试方法

[TestMethod]
        public void MockAlways()
        {
            var mock = new Mock<AccountController>();
            JsonResult json = new JsonResult();
            //new { success = true, value = ViewData["SaveMessage"] }, JsonRequestBehavior.AllowGet
            json.Data = new { success = true, value = "sa" };
            json.JsonRequestBehavior = JsonRequestBehavior.AllowGet;


            mock.Setup(x => x.SaveMasterKeys("ss", 1)).Returns(json);

            var controller = new AccountController();
            var result = controller.SaveMasterKeys("ss", 1) as JsonResult;

            Assert.AreEqual(mock.Object.SaveMasterKeys("ssxs", 1), result.Data.ToString());
        }

我收到一个无效的设置错误。有没有办法解决这个错误？

Answer 1

我认为您误解了如何模拟控制器的操作。您正在模拟它，然后将其与模拟控制器进行比较。这不是一种方法（这就像检查是否 true == true.

基本上这个错误意味着 Moq 不能覆盖非虚拟成员（这是不言自明的）。您应该将方法的签名更改为 virtual 以允许覆盖它。

但是 - 你不应该嘲笑这样的行为。相反，您应该模拟其依赖项（服务、上下文、网关等）并检查是否可以使用已知的输入值在不模拟操作本身的情况下获得预期结果。
