Question: I am working on an ASP.NET WebForm application using MVP pattern. For every Web Form, there is a Presenter class associated to handle UI and Business logic. However, I had problem when writing unit tests for Presenters, since session values are used in presenters. And there is no HTTP context exists during execution of the unit test ( BTW I use nUnit ), making it is impossible to write unit test for presenters.

Anyone can explain how to unit test these presenters?

Thanks

Answer: 
Action Script 3 + Flash Media Server or opensource Red5 server

Architecturally, you need a server to relay the video/audio to both parties, since they cannot connect directly.

You need a Silverlight or Flash 'movie' running in the browser, which you have written, and you need a server to do the relaying.

Its relatively straightforward using **Haxe**.

[Haxe](http://haxe.org) is a Free language for creating both Flash 'movies' and server applications (and more; read their homepage).

One of the Haxe-related servers that is available for Free is [HaxeVideo](http://code.google.com/p/haxevideo/) - literally a video server that (among other things) supports live streaming from clients. Run HaxeVideo on a server and you can easily make Flash clients (written in the Haxe language naturally) do video chat.

There are several sites that do precisely this e.g. [Reel Portal](http://www.reelportal.com/) and [DoVisio](http://www.dovisio.com/)

If you anticipate a very high volume you can turn to $$$ servers such as [Wowza](http://www.wowzamedia.com/) or [Flash Media Server (FMS)](http://www.adobe.com/products/flashmediaserver/), or you can simply add peering support to HaxeVideo.
