pairwiseCompare<S, T> function

Matcher pairwiseCompare <S, T>(Iterable<S> expected, bool comparator(S a, T b), String description)

A pairwise matcher for Iterables.

The comparator function, taking an expected and an actual argument, and returning whether they match, will be applied to each pair in order. description should be a meaningful name for the comparator.

Implementation 

Matcher pairwiseCompare<S, T>(
        Iterable<S> expected, bool comparator(S a, T b), String description) =>
    new _PairwiseCompare(expected, comparator, description);
