Feature: Consider supplying a static redirect

[KathleenDollard]

WebForms apps sometimes have a static method in each page that allow the page to be open with pre-work and then a redirect (mine do).

Consider a static redirect method in testable page.

I hacked this by supplying a StaticContext, but I think a static redirect might be better.

Can you share some pseudo-code of what this static method looks like that you want to test?

[KathleenDollard]

Sure,

public static void Open()
{
    // Sometimes code here
    HttpContext.Current.Response.Redirect("~/Pages/Projects/MyPage.aspx");
}

Current work around is to create a static method shown below. The CreateRedirectPath is a testable method.

public static void Open()
{
    // More stuff maybe here
    RedirectToPage("Projects", "MyPage");
}

protected internal static void RedirectToPage(
            string categoryDirectory,
            string className)
{
    StaticContext.Response.Redirect(CreateRedirectPath(categoryDirectory, className));
}

public new HttpContextBase Context
{
    get
    {
        return StaticContext;
    }
}

private static HttpContextBase context;
public static HttpContextBase StaticContext
{
    get
    {
        if (context == null) context = new HttpContextWrapper(HttpContext.Current);
        return context;
    }
    set
    {
        context = value;
    }
}

And I test it like

   public void Open_method_creates_page()
        {
            // Arrange

            // Act
            MyPage.Open();
            var path = MyPage.CreateRedirectPath("Projects", "MyPage");

            // Assert
            ResponseMock.Verify(x => x.Redirect(path), Times.Exactly(1));

        }

I have reservations about making the TestablePage.HttpContext static as this will hinder the ability for test suites to be run in parallel

[KathleenDollard]

I think we encounter a problem if Context is instance or if it is static

• If static, parallel test are affected, but all interacting code can access the same Context/Session, etc
• If instance, parallel tests work, but I haven't figured out a way to access a consistence context. For example, I have lots of code in common locations (much stuffed into static methods on Global.asax) that accesses context.

I do not yet see a way to have a per test context.
