The new external classes/exporters are covered by unit tests, to manually test you can do the following:

1. Log in as admin
2. Enable web service
3. Enable web service protocols at admin/settings.php?section=webserviceprotocols
4. Generate, and make note of, token for the admin user
5. Select Reports from the user menu
6. Create a new report from Users report source
   • Make a note of the report ID (look at URL: reportbuilder/edit.php?id=<REPORTID>)
7. Execute the following web service request

   $ curl --silent "<WWROOT>/webservice/rest/server.php?moodlewsrestformat=json" --data "wstoken=<TOKEN>&wsfunction=core_reportbuilder_retrieve_report&reportid=<REPORTID>" | python -m "json.tool"

8. Confirm the following output:

   {

   "data": [

   {

   // Report data.

   },

   "details": [

   {

   // Report details.

   },

   ],

   "warnings": []

   }

9. Confirm that the "Report data" contains the data within your report:
   • "headers" should contain a list of headers
   • "rows" should contain an array of items, each containing a "columns" property with the actual row data
   • "totalrowcount" should contain total row count
10. Confirm that the "Report details" contains information about the report you created (name, source, modified by, etc)
