Annotation Type Unroll

@Retention(value=RUNTIME)
@Target(value={TYPE,METHOD})
public @interface Unroll

Indicates that iterations of a data-driven feature should be made visible as separate features to the outside world (IDEs, reports, etc.). By default, the name of an iteration is the feature's name followed by a consecutive number. This can be changed by providing a naming pattern after @Unroll. A naming pattern may refer to data variables by prepending their names with #. Example:

 @Unroll("#name should have length #length")
 def "name length"() {
   expect:
   name.size() == length

   where:
   name << ["Kirk", "Spock", "Scotty"]
   length << [4, 5, 6]
 }
 

Alternatively, the naming pattern can also be embedded in the method name:

 @Unroll
 def "#name should have length #length"() {
   ...
 }
 

The Unroll annotation can also be put on a spec class. This has the same effect as putting it on every data-driven feature method that is not already annotated with Unroll. By embedding the naming pattern in the method names, each method can still have its own pattern.
