Create a few courses. Create multiple forums in each course. Enrol a user into one of the courses. Create a web service client (similar to the one attached) that includes the course they are enrolled in in the courseids array. Execute the client and ensure the forums for that course are returned. Edit the courseids array so that it is empty. Execute the client and ensure the forums for the course they are enrolled in are returned. Add the courseids for the courses they are not enrolled in. Execute the client and ensure a capability error is thrown. Run the PHP Unit test (phpunit -c mod/forum/phpunit.xml).
