The Cookbooks are a new type of format for me - these are quick to illustrate how to use a technology by putting forward very code focused snippets and examples.
Since the focus is simplicity and speed, most recipes don't require any additional explanation other than the code itself.
Finally – I am looking at this as a living document – I’m going to keep adding recipes and examples as I run into them. Feel free to provide more in the comments and I’ll look to incorporate them into each cookbook.

Mockito
Hamcrest
Apache HttpClient 4
These cookbooks are all based on the github project. Watch and fork it at will - the project is designed with simplicity in mind, so each recipe is done as a very simple test you can play with to understand the example.
