 * The `$fields` argument can always be unset, even if `$count` is true, as that parameter will already distinguish in the cache key between whether to store a count or not.
 * For the unit tests, it would be better to have three distinct tests (only one assertion per test):
     * Run the same query twice, once with `$fields` set to `all`, the other with `$fields` set to `ids`.
     * Another one similar to the above, but with `$count` set to `true` in both queries.
     * Run the same query twice (with the same `$fields` value!), but one time with the `$count` argument as true.
+    * Run the same query twice, once with `$fields` set to `all`, the other with `$fields` set to `ids`. `$wpdb->num_queries` should match.
+    * Another one similar to the above, but with `$count` set to `true` in both queries. `$wpdb->num_queries` should match.
+    * Run the same query twice (with the same `$fields` value!), but one time with the `$count` argument as true. `$wpdb->num_queries` should differ.
