+- Abstract
+	- [Pytest](https://docs.pytest.org/en/stable/) is a popular testing framework for Python known for its simplicity. It breaks away from the class-based structure, offering a more flexible and intuitive approach. (Yep. More Pythonic than [unittest](https://docs.python.org/3/library/unittest.html)!)

+- Note
+	- 雖不追求100%測試覆蓋率，但我在寫測試時都會裝上[Pytest-cov](https://pytest-cov.readthedocs.io/en/latest/readme.html)插件以掌握專案當下覆蓋率的情況
+		- 透過``--cov``引數調用，例如``pytest --cov=./src ./tests``
+	- 專案越肥大通常測試會花上更多時間，搭配[Pytest-xdist](https://pytest-xdist.readthedocs.io/en/stable/distribution.html)插件可簡單地將測試平行化以節省寶貴時間
+		- 透過``-n``引數調用，例如``pytest -n auto``
+		- 善用pytest namespace可以將某些資料暫存給後續測試使用，進一步節省測試時間
+		- 若測試物件之間有依賴性，可使用xdist_group_mark將物件分群，同群的物件將會被同一行程執行
+		- 平行化通常伴隨更多資源的消耗，使用時需小心～
+	- Pytest也支援[pyproject.toml](https://docs.pytest.org/en/stable/reference/customize.html#pyproject-toml)進行配置
