Solidify Fragile Tests

Joe Ferguson shares a tip on how to make a version of PHPUnit’s assertArraySubset where the order of the array does not matter.

The problem with this test is that `assertArraySubset()` will fail if the items in the array are out of order. And since we don’t have an `ORDER BY` on our query in our data source we cannot guarantee the order of the returned data.
