I'm Lendude on drupal.org, long time core contributor, a subsystem maintainer for Views in Drupal core and co-Initiative lead for the PHPUnit Initiative for Drupal core.
Kickstart for Automated testing in Drupal (core)
Help people get up and running with writing automated tests for Drupal (core), helping them understand the different types of tests available to them. Help set up a working environment where you can run core tests.
Very much aimed at backend developers, I will assume no prior knowledge but will probably deep dive pretty quickly.
