In a catalog UI test, after sorting by price you need to check the order of the products. Write a helper function isSortedByPrice: it takes a list of products, each with a price, and a direction, ascending or descending, and returns true if the list is sorted. Then show how to call it in the test's assertion.

How to approach it

They're checking whether you can write a simple but correct order check: a pairwise non-strict comparison of neighbors, both directions, edge cases. And whether you can build it into a test so the test doesn't pass vacuously and it's clear what broke when it fails.
