A) General Verify that complete PHPUnit runs are passing (GHA, ToBiC...) for all branches. B) Testing instructions for MOODLE_311_STABLE and master Install local_codechecker in the site. Run this (see the important note below about the HEAD alternatives and commits): git diff --pretty="" --name-only HEAD~2..HEAD | \ xargs local/codechecker/phpcs/bin/phpcs --standard=moodle --extensions=php \ --sniffs=moodle.PHPUnit.TestCaseNames -p && echo "Yay" Verify that you get 84 (for master) and 84 (for 311_STABLE) dots in the output, without any error and with "Yay" printed at the end. Init phpunit: php admin/tool/phpunit/cli/init.php Run this (see the important note below about the HEAD alternatives and commits): git diff --pretty="" --name-only HEAD~2..HEAD | \ xargs -n 1 -I {} bash -c "echo {}; vendor/bin/phpunit {} > /dev/null || echo ERROR" Verify that you don't get any "ERROR" output, that means that all the tests modified can be run individually. Run this (see the important note below about the HEAD alternatives and commits): git diff --pretty="" --name-only HEAD~2..HEAD | \ grep -v '/tests/.*_test.php' Verify that no files are returned. That means that we only have modified _test.php files within tests/ directories. Run this: find . -name "questiontype_test.php" -o \ -name "upgradelibnewqe_test.php" -o \ -name "behaviourtype_test.php" Verify that no files are returned. That means that all files have been renamed ok. Important Note : the HEAD in the above commands assumes that the branches have been integrated without any merge commit. You may need to replace them by the real commits if the issue has been integrated with merge commit. Here there are the commit details: 311_STABLE: HEAD = 950c3a59ccf854eb3f925e34b521bb01eae51107 master: HEAD = b3c4bd62507ce8c1dfe79998f6bf714793cb6c4d
