Argus Panoptes
This is a visual testing module for Codeception., (*1)
Usage
Install the module using composer and add Argus, together with
WebDriver, to the modules in your suite.yml file, and sprinkle
$I->eyeball("filename/description") through your test., (*2)
Run your tests and they should fail due to new screen-shots. Look
through all the *.result.png files and make sure they look as they
should, and rename them to *.original.png., (*3)
Now Argus will compare the screen-shots of new test runs with the
originals and fail if detecting any differences. It will also leave the
new *.result.png file and a *.diff.png highlighting the
differences for inspection. Replace the *.original.png file with the
corresponding *.result.png to accept the changes, or fix the error., (*4)
