 **Base class:** Extend `Tests\Support\PluginTestCase` (registers plugin namespaces in `setUp`). Pure-PHP tests may extend `CodeIgniter\Test\CIUnitTestCase` directly.
+- Run PHPUnit tests: `composer test`
+- Tests must pass before submitting changes
+- **One test file per class under test.** A controller, model, library, or helper gets exactly one test file covering all of its behavior — `Item_kits.php` → `tests/Controllers/Item_kitsTest.php` (or `Item_kitsControllerTest.php`, matching this codebase's existing `*ControllerTest.php` suffix for controllers), `Sale_lib.php` → `tests/Libraries/Sale_libTest.php`, etc. Do not create feature- or endpoint-scoped test files alongside a class's main test file (e.g. no `Item_kitsBarcodeTest.php` next to `Item_kitsControllerTest.php`) — add the new test methods to the existing file for that class instead. If no test file exists yet for the class, create the one canonical file rather than a narrowly-scoped one.
