## 伺服器機器與伺服器程式 { #server-machine-and-server-program }

有個命名上的小細節請留意。💡

「server（伺服器）」一詞常同時用來指遠端／雲端電腦（實體或虛擬機器），也用來指在該機器上執行的程式（例如 Uvicorn）。

因此看到「server」時，文意可能指這兩者之一。

Existe um pequeno detalhe sobre estes nomes para se manter em mente. 💡

cluster, it is recommended to write unit tests or REST tests instead.

In short, most new functionality should come with unit tests, and optionally
REST tests to test integration.

==== Refactor code to make it easier to test

Unfortunately, a large part of our code base is still hard to unit test.
Sometimes because some classes have lots of dependencies that make them hard to
