/**
* Saves failed tests into tests/_output/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.
