Jazoon 2013 – Spock: boldly go where no test has gone before

Jazoon 2013 badgeIf you look at your tests, do you see a lot of repetitive patterns? Or are you looking for a way to express your intent more easily? Then, Spock might be for you. The talk “Spock: boldly go where no test has gone before” by Andres Almiray (slides on slideshare) gave a good introduction to the framework. Here is an example:

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
    }
}

In a nutshell, this creates three tests, running the assertion name.size() == length for each tuple of values. Here is an example how to test a stack.

But this is just one of many ways which you can use to describe tests that Spock should execute for you. The page “WhySpock” lists 10 reasons.
