We have quite a few of WooCommerce sites that use Sage and they’re doing great, but maintaining them is a bit of a problem as if something “breaks” and for example the payment gateway stops working we’d be losing sales.
Is there a nice workflow for updating plugins and checking if they “break” things?
This was the workflow (on a local setup) we had now:
- WP DEBUG + LOG turned on
- Update WP Core (manually check for “visual problems”, if main links/pages work etc.)
- Update the non-critical plugins (ACF Pro, Offload S3, Compress jpg .,…)
- Update the critical plugins WooCommerce:
** manually check pages and order process (add to cart, cart, checkout,…)
** Update custom theme templates if Woo changed their templates - Update the critical WPML and other plugins (WooCommerce Multilingual, wpml plugin pack,…)
** manually check multilingual pages/subpages and translations if they are ok.
** check links and language switcher,… - update critical GeoIP/our custom plugin (check if redirects work with languages etc.)
- if everything OK, we push live
- make a full order process with a CC card on the live site
How we spot problems:
- visual problems/ Woo css issues (check the Woo pages on mobile/tablet/desktop
- code problems (wp debug, php, mysql logs etc.)
- functional problems (if we get any errors with add to cart/checkout process etc.)
Are there other ways for testing specific plugins (like a custom payment gateway)?
Will the future Trellis have an “solution” for these things? I like how you have a lot of control with Roots products, but the plugins are still a part that we can’t really control that much 
Is there a easier way of doing these things or maybe even some testing workflows? Tips welcomed, thanks
