The test itself looks good.
Like you said, the cut-n-paste code need some cleanup, you didn't need those no-message version and the array version of assertThrows.

>>> This changeset fixes a small corner case where Arrays.parallelPrefix (all variants) failed to throw NPE if the operation was null. If the array or range was empty then op was never examined. The solution in this patch is to add an an explicit Objects.requireNonNull(op) check.
