From 8f74dafce025916ab5bf41664305ac87d397201e Mon Sep 17 00:00:00 2001 From: Michael Ball Date: Thu, 23 Apr 2026 21:44:25 +0000 Subject: [PATCH 01/10] test: setup GitHub Actions CI suite and testing infrastructure - Add GitHub Actions workflow with jobs for Luacheck, Busted, Playwright, and Axe-core. - Configure Busted for Lua unit and model testing with a Postgres service container. - Integrate Playwright for end-to-end and accessibility (axe-core) testing. - Implement database safety guards to ensure tests only run against `snapcloud_test`. - Scaffold test support including factories, DB helpers, and fixture data. - Add Makefile targets and npm scripts for local test execution.
