Hi there.

I'm trying to mock the following in my web control:

Dim urlRequestedByUser As String = Page.Request.QueryString(m_queryStringName)

Basically, when the code calls Page.Request.QueryString(m_queryStringName) I would like to return a mock string value.

I'm difficulty in mocking this code, can anyone suggest something that can help?

Many thanks.

Hi, look at the thread here: ... quest#2744

tillig gives examples how to mock HTTPWebRequest object (the one you are trying to mock) both in natural and reflective mocks.

Once you have the Request object mocked, you can set a "ExpectAndReturn" on the QueryString method.

Let me know if you need further help.

Hi there.

Ok, after some trial and error I got the following to work:

Dim mockPage As System.Web.UI.Page = RecorderManager.CreateMockedObject(GetType(System.Web.UI.Page), Constructor.NotMocked)
        Dim mockHTTPRequest As System.Web.HttpRequest = RecorderManager.CreateMockedObject(GetType(System.Web.HttpRequest), Constructor.Mocked)
        Dim mockQueryString As System.Collections.Specialized.NameValueCollection = RecorderManager.CreateMockedObject(GetType(System.Collections.Specialized.NameValueCollection), Constructor.NotMocked)
        ' Add a default value to the querystring.
        mockQueryString.Add("requestedUrl", "")

        Using recorder As RecordExpectations = RecorderManager.StartRecording
            Dim dummy As Object = mockPage.Request

            Dim dummy2 As Object = mockHTTPRequest.QueryString
        End Using

So in my web control, the code:


is now mocked nicely. Cool.

Cheers for the help.
