我正在尝试编写一个单元测试来测试我的控制器,它使用了session。我理解httpcontext仅从来自浏览器的请求生成的概念,并且因为调用控制器动作形式单元测试,当前上下文将为null。
我尝试根据本文的第一部分http://www.dontpaniclabs.com/blog/post/2011/03/22/testing-session-in-mvc-in-four-lines-of-code/解决此问题,但它仍然不适合我。请参阅下面的代码。
[TestFixtureSetUp]
public void Configure_AutoMapper()
{
_product = new ProductViewModel()
{
Id = Guid.NewGuid(),
Category = Guid.Parse("72E42A11-DFA4-4AB9-A735-5CD5C18396D4"),
Brand = Guid.Parse("96E68B67-60FB-4531-898E-815433B44D89"),
Description = "From test",
CostPrice = Parse("17.00"),
SalePrice = Parse("25.00"),
Quantity = 7,
BusinessId = Guid.Parse("BDF9FB7F-DB40-4365-9872-AECD616ED415")
};
var context = new Mock<ControllerContext>();
var session = new Mock<HttpSessionStateBase>();
context.Setup(m => m.HttpContext.Session).Returns(session.Object);
_productsController = new ProductsController {ControllerContext = context.Object};
var userSessionInfo = new UserSessionViewModel()
{
FirstName = "Junior",
LastName = "Labolz",
BusinessId = Guid.Parse("BDF9FB7F-DB40-4365-9872-AECD616ED415")
};
SessionHelper.AddUserDetailsToSession(SessionHelper.UserDetails, userSessionInfo);
}
[Test]
public void Display_Products_List_On_View_Products_Button_Click()
{
//Set Up
//Act
var viewResult = (ViewResult)_productsController.Index();
//Assert
Assert.That(string.Empty, Is.EqualTo(viewResult.ViewName));
}
public static void AddUserDetailsToSession(string sessionName, UserSessionViewModel userSessionDetails)
{
HttpContext.Current.Session.Add(sessionName, userSessionDetails);
}
**根据理查德的回答,我将其改为**
var context = new Mock<ControllerContext>();
var session = new Mock<HttpSessionStateBase>();
context.Setup(m => m.HttpContext.Session).Returns(session.Object);
var userSessionInfo = new UserSessionViewModel()
{
FirstName = "Junior",
LastName = "Labolz",
BusinessId = Guid.Parse("BDF9FB7F-DB40-4365-9872-AECD616ED415")
};
context.Object.HttpContext.AddUserDetailsToSession(SessionHelper.UserDetails, userSessionInfo);
_productsController = new ProductsController {ControllerContext = context.Object};
产品控制器构造函数
public ProductsController()
{
_productService = new ProductServiceClient();
_userSessionViewModel = (UserSessionViewModel)SessionHelper.GetSessionDetail(SessionHelper.UserDetails);
}
获取会话方法
public static object GetSessionDetail(string sessionName)
{
return HttpContext.Current.Session[sessionName];
}
答案 0 :(得分:0)
我可以看到你的代码包含一个直接引用HttpContext.Current的静态函数。如果你想进行单元测试,你不能这样做,你必须使用注入的HttpContextBase实例。
在您的单元测试中,这些实例将是您的模拟上下文。在生产中,您将设置容器以在请求HttpContextBase时注入HttpContext.Current。
我会将静态方法重写为扩展方法:
public static void AddUserDetailsToSession(this HttpContextBase context,
string sessionName, UserSessionViewModel userSessionDetails)
{
context.Session.Add(sessionName, userSessionDetails);
}
然后从测试中调用它:
context.Object.AddUserDetailsToSession(SessionHelper.UserDetails, userSessionInfo);
