The Spock framework brings simple, elegant testing to Java and Groovy projects. It integrates cleanly with JUnit, so Spock tests can be integrated as part of an existing test suite. Spock also includes an embedded mocking framework that can be used right away.
In this presentation, we'll look at several examples of Spock tests and review most of its capabilities, including mock objects and integration with Spring.
Making Spring Groovy
By Kenneth Kousen
The Spring framework has always had a friendly relationship with dynamic languages. In this presentation, we'll look at all the ways you can add Groovy to Spring to make development easier, ranging from simplifying your configuration files to deploying refreshable beans to using Spock tests in the Spring test context and more.
Groovy works comfortably with existing Java infrastructure, and Spring has special capabilities designed specifically for scripting languages. The combination is very powerful and is an easy way to take advantage of Groovy code simplification.
RESTful Groovy
By Kenneth Kousen
The JAX-RS 2.0 specification is part of Java EE 7, but can be used now. It contains the expected annotations for the HTTP verbs (@GET, @POST, and so on) and mechanisms for retrieving variables, but only a few methods for doing hypermedia. This presentation will review those techniques by adding both structural and transitional links to resource representations. Groovy is used to simplify the code and also to implement a MessageBodyWriter for JSON data.
In addition to simplifying the implementation classes, Groovy also supplies a RESTful client class from the HttpBuilder project. That will be used, as well as the native client implementation classes in JAX-RS 2.0, to build Spock tests for RESTful services.
Prerequisite: Some knowledge of Groovy would be helpful

Grails 2.3 makes it much easier to build RESTful web services from your domain classes, and even includes hypermedia capabilities. This presentation will demonstrate those capabilities and then add a JavaScript client-side framework like AngularJS. The Ratpack framework will also be used as an alternative server-side implementation.
Tests and build files will be included in a GitHub repository.

Groovy has a very easy learning curve for Java developers, so many people become Groovy users without realizing all it can do. This presentation will examine features of Groovy that can make your life easier once you're past the initial adoption stage.
Examples will include closure coercion, mixins, simple runtime metaprogramming, operator overloading, drop and take, a tour through some of the overlooked methods in the Groovy JDK, and more.
