Automated: Pass all PHPUnit tests on ALL databases. A) Before patch Switch to moodle.git branch (or 1 week old integration.git branch, anything not having the patch installed). Install a site in the selected branch. Copy the file backup_restore_test.php into backup/tests/ folder, and run the phpunit test  to compare performance between master and new branch. Run commands (note that it can take a while!): $ php admin/tool/phpunit/cli/init.php $ vendor/bin/phpunit backup/tests/backup_restore_test.php Annotate results B) After patch Switch to integration.git branch, with the patch applied. Repeat the steps 2-5 in previous section C) Compare results Put the before and after results face to face and verify that , for all the amplifications (1, 5, 10, 20); The "Finish backup - time" is always smaller after patch, with differences becoming bigger for growing amplifications. The "Finish restore - time" is always smaller (better) after patch, with differences becoming bigger for growing amplifications. The "Memory after backup" is always bigger (worse) after patch, with differences becoming bigger for growing amplifications. The "Memory after restore" is always bigger (worse) after patch, with differences becoming bigger for growing amplifications. The total "Time" to run the unit test is smaller (better) after the patch. The total "Memory" to run the unit test is bigger (worse) after the patch.
