+Configs: PHPUnit `phpunit.xml` (+ `tests/bootstrap.php`), Playwright `tests/e2e/playwright.config.js`, wp-env `.wp-env.json` + gitignored `.wp-env.override.json`, PHPStan `phpstan.neon` + `phpstan-baseline.neon` (stubs for optional integrations and dynamic constants live in `tests/static-analysis-stubs/`, loaded only during analysis).
+
+## wp-env Instance
+
+Single environment (`"testsEnvironment": false`): one `wordpress`/`cli`/`mysql` container set serves dev, PHPUnit, and E2E. Login: `admin`/`password`. Port precedence everywhere: `WP_BASE_URL` > `WP_ENV_PORT` > `.wp-env.override.json` > `8888` — `npm run env:start` (`bin/wp-env-up.js`) probes for a free port and pins it in the override file, which the Playwright config reads too.
+
+- PHPUnit runs in the container with `WORDPRESS_TABLE_PREFIX=wptests_` (baked into `test:unit:php:base`). Never drop that prefix override: the container's tests config otherwise points at the dev site's own `wp_` tables and the suite install WIPES the site.
+- `bin/wp-env-setup.sh` (wp-env `afterStart`) sets pretty permalinks, provisions the plugin's default settings, and disables the setup-wizard redirect plus the block-based "new look" (`wpmm_new_look=0`) so the classic settings screens are testable. While `wpmm_settings` is missing, the plugin re-flags the install as fresh on every request — provision settings before touching `wpmm_fresh_install`.
+- The environment runs with `SCRIPT_DEBUG=true`, so unminified assets load and no Grunt build is needed for tests; `WPMM_ASSETS_SUFFIX` is empty in this mode.
+
+## E2E Rules (Important)
+
+- `workers: 1`, always. Maintenance mode is a site-wide option; virtually every spec flips global state. Do not raise the worker count or add `fullyParallel`.
+- Specs must leave maintenance mode OFF when they finish, or every later spec sees the 503 page.
+- Use the helpers in `tests/e2e/utils.js` (`setMaintenanceMode`, `activateSettingsTab`, `saveSettingsForm`, `openAsVisitor`) instead of hand-rolling admin flows. They encode three non-obvious constraints:
+  - After any settings save (form POST + redirect), headless Chromium stops producing animation frames for the page, so non-`force` Playwright interactions hang on the "element is stable" actionability check. Helpers use `force: true` plus explicit state assertions.
+  - The settings tabs are hash-driven; navigating to the hash-less settings URL is a same-document navigation, so the previously active tab persists. Always `activateSettingsTab` explicitly.
+  - The save redirect lands on `?updated=1#<tab>` and WordPress strips the query right after load — wait for the redirect response, not the URL.
+- Visitor contexts: `browser.newContext()` inherits the admin `storageState`; `openAsVisitor` clears cookies to get a real logged-out visitor.
+
+## Testing Practices (TDD)
+
+- Red → green: write the failing test first, then only enough code to make it pass. One seam, one test, one minimal implementation per cycle — don't batch-write tests for imagined behavior (vertical slices, not horizontal). Refactoring is a separate review-stage step, not part of the loop.
+- Test behavior through public seams, never internals: the admin-ajax endpoints (`wp_ajax_wpmm_*`), public helpers (`includes/functions/helpers.php`), rendered frontend output, and the settings screens. If a test breaks when you refactor but behavior hasn't changed, it's testing the wrong thing.
+- Expected values must come from an independent source of truth (a known-good literal, the spec, a worked example) — never recompute them the way the code does.
+- Plugin-specific seams and traps (see `tests/ajax-api-test.php`):
+  - Several AJAX handlers guard with plain `die( $msg )` (not `wp_die`); those guard paths CANNOT be exercised through `_handleAjax` — a plain `die()` kills the PHPUnit process with exit code 0.
+  - Handlers wrapped in `catch ( Exception )` swallow the suite's die-exception and answer twice; the test class installs a die handler that throws `WPMM_Ajax_Die_Signal extends Error` instead.
+  - `_handleAjax()` fires `admin_init` without defining `DOING_AJAX`; keep `maybe_redirect` unhooked in tests or a fresh-install flag turns it into a process-killing wizard redirect.
+  - The WP suite auto-excludes tests annotated `@group ajax` — don't add that annotation.
+  - wp-env's sender address `wordpress@localhost` fails PHPMailer validation; filter `wp_mail_from` in mail tests.
