   ----
   
  +Care should be taken when ignoring feature methods in a spec class annotated with `spock.lang.Stepwise` since
  +later feature methods may depend on earlier feature methods having executed.
  +
   === Requires
   
   To execute a feature method under certain conditions, annotate it with `spock.lang.Requires`,
  
positive.code: ----
  
  +@IgnoreRest+ is especially handy in execution environments that don't provide an (easy) way to run a subset of methods.
  
  === IgnoreIf
  
  
negative.code: `Stepwise` only affects the class carrying the annotation; not sub or super classes.  Features after the first
  failure are skipped.
  
  `Stepwise` does not override the behaviour of annotations such as `Ignore`, `IgnoreRest`, and `IgnoreIf`, so care
  should be taken when ignoring feature methods in spec classes annotated with `Stepwise`.
