I'm looking for some in depth end-to-end CQRS examples with a reasonable set of unit tests.

Also, if anyone knows of some CQRS screencasts as well it would be extremely handy.

I'm already aware of these examples

CQRS Info
Super Simple CQRS

There's a implementation here MarkNijhof.

But after reading the documents from the CQRS Info site my favourite resource is Think Before Coding look at the post Tags. (http://thinkbeforecoding.com/)

Some other useful resources...

Microsoft patterns & practices is working on a guidance project called CQRS Journey. The idea is to develop a non-trivial system with multiple bounded contexts and apply CQRS, ES and other patterns & techniques where appropriate and document all lessons learnt along the way. The project is still in flight. Check out the journey progress at http://cqrsjourney.github.com

Code repo is at https://github.com/mspnp/cqrs-journey-code
Doc review via http://pundit.cloudapp.net

The project involves many community members and accepts contribitions!

http://ncqrs.org/

Is a useful resource...

Here is a complete example I wrote for my CQRS lib Scritchy:

Example.Domain: Domain implementation
Example.Specs : Domain behavior specs using MSpec
Example.Web : Example MVC web app (demo at http://scritchyExample.apphb.com )
Example.SignalR : Example html/Javascript/SignalR web app (using the same domain code)

Creating your CQRS app using the Scritchy nuget package is pretty straightforward and gets you up and running in a few minutes

Here's some more informational resources, but unfortunately no end-to-end code samples beyond SimpleCQRS and MarkNijhof.

I have come across a couple other code samples, though I have not yet had time to review them whatsoever:

Udi Dahan would have to be one of the experts in the CQRS field, imo.

Here is a blog about it: http://www.udidahan.com/2009/12/09/clarified-cqrs/

Here is a CQRS podcast (I haven't watched it, but if it's anything like his course presentation it will be great): http://skillsmatter.com/podcast/open-source-dot-net/udi-dahan-command-query-responsibility-segregation/rl-311

Here is a SOA talk (may not be directly relevant but excellent regardless): http://vimeo.com/5022174

If you have the time, I'd recommend popping along to one of Udi's courses when one is nearby, as he covers CQRS in depth.

I recommend this screencast by Chris Tavares. It gives a good overview of CQRS and it shows some good examples in code.

I've got a sample of just the BDD style of unit-tests, it isn't end-to-end, but since you mentioned unit tests I figured it might be of interest. http://lucisferre.net/2011/02/05/behavior-driven-test-driven-domain-driven-design/

There was a great session during aspConf 2012 by Ashic Mahtab.
