Looks good, i like the test re-structuring, just some minor comments on that.
- there are some commented out asserts.
- take or leave the following... the providers could be simplified a little if
you return a Stream rather than a Collection for those make methods:
Supplier<..> s = () -> Collections.synchronizedSortedSet(new
TreeSet<>(BASE_COLLECTION));
Stream.of(s.get(),
s.get().headSet("Foxtrot"),
...)
map(c -> new Object[] {c})
and also use Stream.concat.
