14	make fix-all
15```
16* Validation can be done with:
17```sh
18	composer test
19	# or (targeting more than just PHP)
20	make test-all
21```
22* Check [`composer.json`](../../composer.json) scripts for details about available individual commands.
23* For instance, running a single unit test can be done with:
24```sh
25	composer run-script phpunit -- tests/app/Models/SearchTest.php
