Question

I have method expecting HttpContext type variable.

public string GetQueryStringValues(HttpContext context)

I am writing unit test from article hanselman article using Moq to create/populate HttpContext and pass into the method as follows:

        string url = "http://localhost:51209/WebForm1.aspx?height=6&width=7&length=8&mode=walk";
        HttpContextBase contextbase = MoqHelper.FakeHttpContext(url);
        string result = new Helper(whitelist).GetQueryStringValues(context); 

I get the following error message:

cannot convert from ‘System.Web.HttpContextBase’ to ‘System.Web.HttpContext’

How do I resolve this with out changing the signature for method GetQueryStringValues ??

Please help.

thanks

Unfortunately, you cannot do this without changing signature. However, your signature will be better with abstraction, not concrete type.
