+ // containsExactlyElementsIn (or Hamcrest's similar containsInAnyOrder) isn't a 1 line
+ // trivia... e.g. a.containsAll(b) && b.containsAll(a) isn't sufficient, because it
+ // won't work for duplicates (which we frequently have here); and ordering before is
+ // not viable because FlowEntity is not Comparable, and Comparator based on hashCode
+ // is not a good idea (different instances can have same hashCode), and e.g. on

+ // is, much, more readable), there are cases when looking more closely
+ // at the full toString() output of the flows is still useful, so:
