Behat utilities to manage the test environment

Usage:
  php util_single_run.php [--install|--drop|--enable|--disable|--diag|--updatesteps|--help]

Options:
--install           Installs the test environment for acceptance tests
--drop              Drops the database tables and the dataroot contents
--enable            Enables test environment and updates tests list
--disable           Disables test environment
--diag              Get behat test environment status code
--updatesteps       Update feature step file.
--no-axe            Disable axe accessibility tests.
--scss-deprecations Enable SCSS deprecation checks.

-o, --optimize-runs Split features with specified tags in all parallel runs.
-a, --add-core-features-to-theme Add all core features to specified theme's

-h, --help Print out this help

Example from Moodle root directory:
\$ php admin/tool/behat/cli/util_single_run.php --enable
