# Run the Playwright e2e suite against a small WordPress/PHP version matrix to
# confirm the plugin works on both ends of its declared support window:
#
#   - declared minimum : WP 6.0  / PHP 7.4  (readme.txt "Requires at least" / "Requires PHP")
#   - latest           : WP latest / PHP 8.3
#
# If it passes on the floor and on latest, everything in between is covered, so
# there is no need to bump the declared minimums.
#
# Each row destroys and recreates wp-env so the seeded page tree starts clean and
# the requested core/PHP versions actually take effect. This is slow but correct.
#
# Cores are pinned via **zip URLs** rather than git refs (WordPress/WordPress#x.y):
# git-ref cores all share one cached clone and a `git checkout` to the next row's
# version aborts on the dirty working tree left by the previous row. Zip cores are
# downloaded + extracted fresh, so switching versions can't collide.
#
# WP_DEBUG_DISPLAY is forced off for the run (errors still go to the debug log via
# WP_DEBUG_LOG). Older WP cores can emit PHP deprecations on newer PHP, and any
# on-screen output during login breaks the auth cookie ("Cookies are blocked due to
# unexpected output") — a core/runtime artifact, nothing to do with this plugin.
# Applied via a temporary .wp-env.override.json that is restored/removed on exit.
#
# Usage:  npm run test:e2e:matrix     (or)   bash scripts/test-matrix.sh
# Requires: Docker running, dependencies installed (npm ci), Playwright browsers
# installed (npx playwright install chromium).
