最初にテストコードを書き、テストコードに適用するように毎回phpunitを実行しながら実装していく手法
### first step to do
$ composer create-project –prefer-dist laravel/laravel library
$ cd library
$ php artisan –version
$ ls -al
$ git init
$ git status
$ git add .
$ git commit -m “initial commit”
.env
DB_CONNECTION=sqlite
$ touch database/database.sqlite
phpunit.xml
<php>
<server name="APP_ENV" value="testing"/>
<server name="BCRYPT_ROUNDS" value="4"/>
<server name="CACHE_DRIVER" value="array"/>
<server name="DB_CONNECTION" value="sqlite"/>
<server name="DB_DATABASE" value=":memory:"/>
<server name="MAIL_DRIVER" value="array"/>
<server name="QUEUE_CONNECTION" value="sync"/>
<server name="SESSION_DRIVER" value="array"/>

OK (1 test, 2 assertions)
テストコードを正確に書ければ、phpunitによるメッセージに沿って順番に進めることができる。
ただ、これ、migrationfile, route, model, controller書くだけになのに、時間かかりすぎるな。手が空いている時などはいいかもしれないが、毎回これやってたら開発効率が極端に落ちるように思うので、ケースバイケースだが、積極的には採用しずらい。
