Log suites/tests/steps using Monolog library. Monolog should be installed additionally by Composer.

composer require monolog/monolog

Steps are logged into tests/_output/codeception.log

To enable this module add to your codeception.yml:

extensions:
    enabled: [Codeception\Extension\Logger]

• max_files (default: 3) - how many log files to keep

Saves a screenshot of each step in acceptance tests and shows them as a slideshow on one HTML page. Activated only for suites with WebDriver module enabled.

The screenshots are saved to tests/_output/record_* directories, open index.html to see them as a slideshow.

Add this to the list of enabled extensions in codeception.yml or acceptance.suite.yml:

extensions:
    enabled:
        - Codeception\Extension\Recorder

• delete_successful (default: true) - delete screenshots for successfully passed tests (i.e. log only failed and errored tests).
• module (default: WebDriver) - which module for screenshots to use. Set AngularJS if you want to use it with AngularJS module. Generally, the module should implement Codeception\Lib\Interfaces\ScreenshotSaver interface.

extensions:
    enabled:
        Codeception\Extension\Recorder:
            module: AngularJS # enable for Angular
            delete_successful: false # keep screenshots of successful tests

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

Starting from Codeception 2.1 this extension is enabled by default.

extensions:
    enabled: [Codeception\Extension\RunFailed]

On each execution failed tests are logged and saved into tests/_output/failed file.

This extension demonstrates how you can implement console output of your own. Recommended to be used for development purposes only.
