Spock is a testing and specification framework for Java and Groovy applications. What makes it stand out from the crowd is its beautiful and highly expressive specification language. Thanks to its JUnit runner, Spock is compatible with most IDEs, build tools, and continuous integration servers. Spock is inspired from JUnit, jMock, RSpec, Groovy, Scala, Vulcans, and other fascinating life forms.

class HelloSpock extends spock.lang.Specification {
    def "length of Spock's and his friends' names"() {
        expect:
        name.size() == length

        where:
        name     | length
        "Spock"  | 5
        "Kirk"   | 4
        "Scotty" | 6
    }
}  

Run this example in Spock Web Console
