How We Test - spthemes/best-practices GitHub Wiki

We check that:

1. The theme does not generate PHP fatal errors, warnings, or notices.
2. The block editor works on the front end and in the admin area:
   • Button colors work
   • Full/Wide blocks work
   • Editor styles are present and reflect the front end styles
   • Back end and front end widths match
   • General block editor functionality works
3. All strings are translatable with a text domain that matches the theme name, and a .pot file has been generated.
4. An accessibility test using a tool such as Lighthouse reveals no issues specific to the theme’s design or imported content.
