我已经为下面的行动编写了单元测试。
[HttpPost]
public ActionResult/*ViewResult*/ Create(MyViewModel vm)
{
if (ModelState.IsValid)
{
//Do something...
return RedirectToAction("Index");
}
return View(vm);
}
只有当返回类型为Model
时,测试方法才能访问ViewResult
属性。在上面的代码中,我使用了RedirectToAction
,因此此操作的返回类型不能是ViewResult
。
在这种情况下,你如何对行动进行单元测试?
答案 0 :(得分:67)
所以这是我的小例子:
public ActionResult Index(int id)
{
if (1 != id)
{
return RedirectToAction("asd");
}
return View();
}
测试:
[TestMethod]
public void TestMethod1()
{
HomeController homeController = new HomeController();
ActionResult result = homeController.Index(10);
Assert.IsInstanceOfType(result,typeof(RedirectToRouteResult));
RedirectToRouteResult routeResult = result as RedirectToRouteResult;
Assert.AreEqual(routeResult.RouteValues["action"], "asd");
}
[TestMethod]
public void TestMethod2()
{
HomeController homeController = new HomeController();
ActionResult result = homeController.Index(1);
Assert.IsInstanceOfType(result, typeof(ViewResult));
}
修改
验证结果类型为ViewResut后,您可以投射到它:
ViewResult vResult = result as ViewResult;
if(vResult != null)
{
Assert.IsInstanceOfType(vResult.Model, typeof(YourModelType));
YourModelType model = vResult.Model as YourModelType;
if(model != null)
{
//...
}
}

请注意
Assert.IsInstanceOfType(result,typeof(RedirectToRouteResult));
已被弃用。
新语法是
Assert.That(result, Is.InstanceOf<RedirectToRouteResult>());
答案 2 :(得分:0)
试试这段代码:
dynamic result=objectController.Index();
Assert.AreEqual("Index",result.ViewName);
