/**
 * Executes tests.
 *
 * Usage:
 *
 * * `codecept run acceptance`: run all acceptance tests
 * * `codecept run tests/acceptance/MyCept.php`: run only MyCept
 * * `codecept run acceptance MyCept`: same as above
 * * `codecept run acceptance MyCest:myTestInIt`: run one test from a Cest
 * * `codecept run acceptance checkout.feature`: run feature-file
 * * `codecept run acceptance -g slow`: run tests from *slow* group
 * * `codecept run unit,functional`: run only unit and functional suites
 *
 * Verbosity modes:
 *
 * * `codecept run -v`:
 * * `codecept run --steps`: print step-by-step execution
 * * `codecept run -vv`:
 * * `codecept run --debug`: print steps and debug information
 * * `codecept run -vvv`: print internal debug information
 *
 * Load config:
 *
 * * `codecept run -c path/to/another/config`: from another dir
 * * `codecept run -c another_config.yml`: from another config file
 *
 * Override config values:
 *
 * * `codecept run -o "settings: shuffle: true"`: enable shuffle
 * * `codecept run -o "settings: lint: false"`: disable linting
 * * `codecept run -o "reporters: report: \Custom\Reporter" --report`: use custom reporter
 *
 * Run with specific extension
 *
 * * `codecept run --ext Recorder` run with Recorder extension enabled
 * * `codecept run --ext DotReporter` run with DotReporter printer
 * * `codecept run --ext "My\Custom\Extension"` run with an extension loaded by class name
 *
 * Full reference:
 * ```
