Is it possible to see a file that has been downloaded on running visual studio webtest.?

Question

Hi There,
I'm not sure if this is the right place to post the query :)
I'm new to visual studio performance testing. I created a webtest script using Visual Studio Ultimate 2013 for downloading a .pdf from a website. I gather from the response bytes that the script is doing its job.
My question is where could I find the .pdf file if it is getting downloaded? or is it not downloading the file physically.
Appreciate your support. Many thanks in advance.

I would not expect the file to be saved automatically in a web test. The file's contents will be in the "bodybytes" and "bodystring" of the relevant HTMLO response. So you can write some file writing code in a plugin.
Here is a version of the plugin that I have used:
public override void PostRequest(object sender, PostRequestEventArgs e)
string body = e.Response.BodyString;
if (body == null)
e.WebTest.AddCommentToResult("No response PDF");
else if (string.IsNullOrWhiteSpace(body))
e.WebTest.AddCommentToResult("PDF is empty");
else if (e.Response.BodyString.StartsWith("\x0d\x0a%PDF"))
string fileName = "The_response.pdf");
int bodyLength = e.Response.BodyString.Length;
File.WriteAllBytes(fileName, e.Response.BodyBytes);
string message = string.Format("PDF of {0} bytes written to file {1}", bodyLength, fileName);
e.WebTest.AddCommentToResult(message);
else
e.WebTest.AddCommentToResult("Unknown file contents");
