Before upgrade: Set up a tool proxy with http://lti.tools/test/tp.php so you can see the launch parameters being passed. Create an instance of this tool proxy, launch it and make a note of the names of each parameter passed. After upgrade: Re-launch the tool proxy from above and check that the same parameters are still being passed (values may be different, just check the names). Delete and re-create the tool proxy with http://lti.tools/test/tp.php - do not enable any of the new capabilities (see comment in this issue for a list). Create an instance of this tool proxy, launch it and check that none of the parameters associated with the new capabilities were passed (unlike as they were before). Delete and re-create the tool proxy with http://lti.tools/test/tp.php - enable all of the new capabilities (see comment in this issue for a list). Create an instance of this tool proxy, launch it and check that all of the parameters associated with the new capabilities were passed (just as they were before).
