Testing Groovy and Java Systems

Most Java developers work with unit testing frameworks like JUnit, and use mocks and stubs generated by third-party libraries. Groovy has both features built into the language. This presentation will show you how to write tests for Groovy, Java, and mixed projects that are simple, easy to write, and run on your existing test infrastructure.

Examples will be given showing how GroovyTestCase simplifies JUnit, how to test Groovy scripts, how to build stub implementations with Expandos, and how to take advantage of the built-in Groovy classes MockFor and StubFor. The Spock framework will also be used to show how to create data-driven tests. All of the examples can be run together in the same Java-based or mixed Java and Groovy project.
