When we write a feature method in our Spock specification to test our class we might run into long running methods that are invoked. We can specify a maximum time we want to wait for a method. If the time spent by the method is more than the maximum time our feature method must fail. Spock has the @Timeout annotation to define this. We can apply the annotation to our specification or to feature methods in the specification. We specify the timeout value as argument for the @Timeout annotation. Seconds are the default time unit that is used. If we want to specify a different time unit we can use the annotation argument unit and use constants from java.util.concurrent.TimeUnit to set a value.

To ignore feature methods in our Spock specification we can use the annotation @Ignore. Any feature method or specification with this annotation is not invoked when we run a specification. With the annotation @IgnoreRest we indicate that feature methods that do not have this annotation must be ignored. So any method with the annotation is invoked, but the ones without aren’t. This annotation can only be applied to methods and not to a specification class.
