When you are using Cache in your Business Logic, then running tests will fail because there will be no HttpContext available. This is a workaround:

Add this to your App.Config:

1
2
3

<appSettings>
     <add key="AppPhysicalDir" value="..."/>
</appSettings>

Then add these lines of code to your “public static void MyClassInitialize(TestContext testContext)”:

1
2
3
4
5
6
7
8
9
10
11
12

using System.Configuration;
using System.Web.Hosting;
using System.Web;
 
...
 
 
string appVirtualDir = "/";
string appPhysicalDir = ConfigurationManager.AppSettings["AppPhysicalDir"];
string page = "/default.aspx";
string query = string.Empty;
TextWriter output = null;
SimpleWorkerRequest workerRequest = new SimpleWorkerRequest(appVirtualDir, appPhysicalDir, page, query, output);
HttpContext.Current = new HttpContext(workerRequest);

Are there other ways of doing this?
