Applied the following changes to various testcase classes: - Namespaced with component[\level2-API] - Moved to level2-API subdirectory when required. - Fixed incorrect use statements with leading backslash. - Remove file phpdoc block - Remove MOODLE_INTERNAL if not needed. - Changed code to point to global scope when needed. - Fix some relative paths and comments here and there. - All them passing individually. - Complete runs passing too. Special mention to: - The following task tests have been moved within the level2 directory: - \core\adhoc_task_test => \core\task\adhoc_task_test - \core\scheduled_task_test => \core\task\scheduled_task_test - \core\calendar_cron_task_test => \core\task\calendar_cron_task_test - \core\h5p_get_content_types_task_test => \core\task\h5p_get_content_types_task_test - \core\task_database_logger_test => \core\task\database_logger_test - \core\task_logging_test => \core\task\logging_test - The following event tests have been moved within level2 directory: - \core\event_context_locked_test => \core\event\context_locked_test - \core\event_deprecated_test => \core\event\deprecated_test - \core\event_grade_deleted_test => \core\event\grade_deleted_test - \core\event_profile_field_test => \core\event\profile_field_test - \core\event_unknown_logged_test => \core\event\unknown_logged_test - \core\event_user_graded_test => \core\event\user_graded_test - \core\event_user_password_updated_test => \core\event\user_password_updated_test - The following output tests have been moved within level2 directory: - \core\mustache_template_finder_test => \core\output\mustache_template_finder_test - \core\mustache_template_source_loader_test => \core\output\mustache_template_source_loader_test - \core\output_mustache_helper_collection_test => \core\output\mustache_helper_collection_test - The following tests have been moved to their correct tests directories: - lib/tests/time_splittings_test.php => analytics/tests/time_splittings_test.php - All the classes and tests under lib/filebrowser and lib/filestorage belong to core, not to core_files. Some day we should move them to their correct subsystem. - All the classes and tests under lib/grade belong to core, not to core_grades. Some day we should move them to their correct subsystem. - The core_grades_external class and its \core\grades_external_test unit test should belong to the grades subsystem or, alternatively, to \core\external, they both should be moved together. - The core_grading_external class and its \core\grading_external_test unit test should belong to the grading subsystem or, alternatively, to \core\external, they both should be moved together. - The \core\message\message and \core\message\inbound (may be others) classes, and their associated tests should go to the core_message subsystem. - The core_user class, and its associated tests should go to the core_user subsystem. - The \core\update namespace is plain wrong (update is not valid API) and needs action 1) create it or 2) move elsewhere.
