This package is a work in progress. It will contain all the matchers you were missing. If you have a good general purpose matcher, submit a PR!
Currently we have:
isAfter(Comparable)isAfterOrEqualTo(Comparable)isBefore(Comparable)isBeforeOrEqualTo(Comparable)
iterableStartsWith(Iterable)iterableEndsWith(Iterable)
stringContainsNTimes(String, int)
throwsTestFailurethrowsTestFailureContaining(String)
