ASP.NET MVC中的单元测试应用程序变量

Question

Hi I am having trouble unit testing my application that use application variables. Below is my test method. accController.Clist(cIn) calls methods that use application variables that are read in from the global.asax file. How and where do I declare it so that the application variables are actually used.

[TestMethod]
public void TestGetCompanyList()
{
    var accController = new AccSerController();
    CInt cInt = new CInt();
    cIn.Iss = "Other";
    cIn.Tick = "BK";
    var result = accController.GetClist(cIn) as IEnumerable<CList>;
    Assert.IsNotNull(result);
}

I know that mocking is used, but I am not that experienced with mocking. Also I did not write the code (controllers, models, etc), so i cannot change the layout of it.

Btw I do not have any interfaces, abstract classes, or virtual methods, most other examples are working with one of those.

I'd look at using the AmbientContext pattern

This basically acts as a mockable wrapper around variables that are static or otherwise difficult to access

It will allow you to keep your application variables declared in the global.asax, but to overwrite them at test time
