/**
 * Saves failed tests into tests/log/failed in order to rerun failed tests.
 *
 * To rerun failed tests just run the `failed` group:
 *
 * ```
 * php codecept run -g failed
 * ```
 *
 * To change failed group name add:
 * ```
 * --override "extensions: config: Codeception\Extension\RunFailed: fail-group: another_group1"
 * ```
 * Remember: if you run tests and they generated custom-named fail group, to run this group, you should add override too
 *
 * Starting from Codeception 2.1 **this extension is enabled by default**.
 *
 * ``` yaml
 * extensions:
 *     enabled: [Codeception\Extension\RunFailed]
 * ```
 *
 * On each execution failed tests are logged and saved into `tests/_output/failed` file.
