Question

我有一个MVC控制器类，我正在尝试进行单元测试。

特定的ActionResult就像这样

public ActionResult Create(Shipment newShipment)
{
   do some stuff to create a shipmentID
...
   return RedirectToAction("AddUnit",newShipment.ShipmentID);
}

我已经模拟了控制器上下文等，现在我想测试传递给RedirectToAction调用的newShipment.ShipmentID是我期望的。

我有一个测试（在设置阶段有大量的事情嘲笑）

    [Test]
    public void CreateSuccess()
    {
        //Arrange
        var shipment = new Shipment();
        shipment.Widgets = 2; //Make sure it a valid shipment otherwise
        //Act
        var result = controller.Create(shipment) as RedirectToRouteResult;
        //Assert
        Assert.IsNotNull(result);
        Assert.AreEqual("AddUnits", result.RouteValues["action"]);
        Assert.IsNull(result.RouteValues["controller"]);
        ...

现在我想找一个Assert来检查我传递给RedirectToAction的shipmentID是否正确。如何检索其值？

（我相信这段代码适用于实际（即实际视图获取正确的货件ID），但我想编写单元测试。）

实际上，RedirectToActions可以采用参数;下面是我如何在一个中测试正确参数的简化示例。我正在使用NUnit＆amp; FluentAssertions在这里。

[HttpPost]        
public ActionResult RedirectMethod()
{
     return RedirectToAction("Index", "Home", new { parameter = "Value" });
}

然后测试：

[Test]
public void RedirectSetsExpectedParameters()
{
    var result = controller.RedirectMethod();
    var redirectResult = result.As<RedirectToRouteResult>();

    var expectedRedirectValues = new RouteValueDictionary
        {
            { "parameter", "Value" },
            { "action", "Index" },
            { "controller", "Home" }
        };

    redirectResult
       .RouteValues
       .ShouldBeEquivalentTo(expectedRedirectValues, 
       "The redirect should look as I expect, including the parameters");
}

这里我给出了一个重定向到行动的样本

public ActionResult Signupsuccess(string account_code, string plan)
{
   ..........
  do some stuff

  return RedirectToAction("SubscriptionPlan", "Settings");

}

我已经模拟了controllercontext并将一些参数传递给从控制器到测试方法的RedirectToAction调用。最后它测试了预期和实际

[TestMethod的（）]

 public void SignupsuccessTest()
       {
            HomeController target = new HomeController(); // TODO: Initialize to an appropriate value
            string account_code = "B898YB7"; // TODO: Initialize to an appropriate value
            string plan = "Application-BASIC"; // TODO: Initialize to an appropriate value

            var ControllerContext = new Mock<ControllerContext>();
            var context = target.HttpContext;

            ControllerContext.SetupGet(p => p.HttpContext.Session["MerchantID"]).Returns("15");
            ControllerContext.SetupGet(p => p.HttpContext.Session["FriendlyIdentifier"]).Returns("3d649876-19f5-48d2-af03-ca89083ae712");

            target.ControllerContext = controllerContext.Object;       

            var action = (RedirectToRouteResult)target.Signupsuccess(account_code, plan);

            action.RouteValues["action"].Equals("SubscriptionPlan");
            action.RouteValues["controller"].Equals("Settings");

            Assert.AreEqual("SubscriptionPlan", action.RouteValues["action"]);
            Assert.AreEqual("Settings", action.RouteValues["controller"]);          
        }

我希望它对你有所帮助。谢谢你
