Spock
This document discusses Spock, a testing framework for Groovy and Java applications. It provides an overview of Spock's features for state based testing, data driven testing using where blocks and data tables, and interaction based testing using Spock's mocking framework. It also mentions extensions for listeners, interceptors, Spring integration, and new features in version 0.7 like grouping interactions and better mocking failure messages. Resources listed at the end include Spock's homepage, documentation, and a link to an article explaining the difference between mocks and stubs.
