+Feature: Profile arbitary code execution
+
+  Scenario: Profile a function that doesn't do anything
+    Given a WP install
+    And a wp-content/mu-plugins/lame-function.php file:
+      """
+      <?php
+      function runcommand_do_nothing() {
+
+      }
+      """
+
+    When I run `wp profile eval 'runcommand_do_nothing();'`
+    Then STDOUT should be a table containing rows:
+      | time | query_time | query_count | cache_ratio | cache_hits | cache_misses | request_time | request_count |
+      | 0s   | 0s         | 0           |             | 0          | 0            | 0s           | 0             |
+
+  Scenario: Profile a function that makes one HTTP request
+    Given a WP install
+
+    When I run `wp profile eval 'wp_remote_get( "http://apple.com" );' --fields=request_count`
+    Then STDOUT should be a table containing rows:
+      | request_count |
+      | 1             |
+
+  Scenario: Profile calls to the object cache
+    Given a WP install
+
+    When I run `wp profile eval 'wp_cache_get( "foo" );' --fields=cache_hits,cache_misses`
+    Then STDOUT should be a table containing rows:
+      | cache_hits    | cache_misses |
+      | 0             | 1            |
