1	1	Latest changes can be found in log:rjollos.git:t10018.2:
2	2	* Hint for future: use `FunctionalTestEnvironment.grant_perm` and `FunctionalTestEnvironment.revoke_perm` and it won't be necessary to call `FunctionalTestEnvironment.restart`. See [11764] and #11028. After these changes execution time came down from 30+ seconds to 13 seconds. See also #11443.
3		* I organized some test cases into a class. The pattern is different from what is used for functional tests in the codebase, but I think it may be an improvement since we can eliminate redundant code.
