so to add HttpContext.Current.Request.QueryString in unit test

You will need to mock the HttpContext so you can set values. Just trying to get things out won't work as they won't exist. See here for something similar: https://stackoverflow.com/questions/9624242/setting-httpcontext-current-session-in-a-unit-test — sr28, Feb 19 '20 at 13:24

You need to set a value to HttpContext.Current, otherwise, it will be null. Something like:

HttpContext.Current = new HttpContext(
    new HttpRequest(filename: "", url: "http://some.url", queryString: ""),
    new HttpResponse(new StringWriter())
);
