Ignore a Spock test if running in Travis CI
Thanks to Spock IgnoreIf annotation it is easy to ignore a specification running in Travis CI.
import spock.lang.IgnoreIf
import spock.lang.Specification
class ClassUnderTestSpec extends Specification {
@IgnoreIf( { System.getenv('TRAVIS') as boolean } )
def "test which fials if run by Travis CI"() {
}
