+### Test
+
+テスト用のライブラリをインストールしてください。
+
+```sh
+pip install -r requirements-dev.txt
+```
+
+テストを実行する
+
+```sh
+pytest tests/
+# ログを出力する場合
+# pytest -s tests/
+```
+
+### Lint
+
+
+```sh
+pip install -r requirements-dev.txt
+```
+
+**lintを実行する方法**
+
+```sh
+ruff check .
+```
+
+例えば使われていない変数が存在する場合はなどは以下のように表示される
+
+```log
