The Magento Marketplace Extension Quality Program will incorporate version 3 of the Code Sniff test into automated testing on 7/11/19.
With the assistance of ExtDN and the community (Thank You everyone!), there have been several updates and changes to the Code Sniff test. Included with this effort, we also consolidated the test across Magento (internally and externally).
Our desire is to keep this test as up to date as possible, but we recognize that we also need to give extension developers time to understand any new criteria that could potentially cause their submissions to fail. Due to this, we have decided to create two different update cadences, Warnings and Fixes and Errors.
Warnings and Fixes: New warnings (Sev 9 and below) or fixes to existing sniffs, if available, will be updated the 1st week of each month. Notifications will go out via social media and in email as to what has changed.
Errors: Any new errors (Sev 10) will be added once a quarter. To make it easy to remember, this update will coincide with the Magento patch release schedule. Notifications will go out via devblog, social media and in email detailing any changes a month prior to release.
To assist you with troubleshooting any errors, we are now showing the test version number in the test report as well.
You can find all versions of this test on github and packagist:
