 Nyash provides a macro-powered lightweight test runner in Phase 16 (MVP).
 
 - Enable and run tests in a script file:
-  - `nyash --run-tests apps/tests/my_tests.nyash`
+  - `nyash --run-tests apps/tests/my_tests.hako`
   - Discovers top-level `test_*` functions and Box `test_*` methods (static/instance).
 - Filtering: `--test-filter NAME` (substring match) or env `NYASH_TEST_FILTER`.
 - Entry policy when a main exists:
