018第11章 TESTING YOUR CODE

💛20230118晨讀感言：

💔學習設置測試用例的語法需要一些時間來適應，但一旦你設置了測試用例，就可以直接為你的函數添加更多的單元測試。

💔至此，python 的基礎語法已經告一段落了，接下來就是 進入本書 第二階段：實作，本書有 三個 project 要實作，所以，每日晨讀內容進度將會 視 對程式的理解和實作進度 而有所不同。

💛晨讀摘要：

💚211 Unit Tests and Test Cases： A _unit test_ verifies that one specific aspect of a function’s behavior is correct. A _test case_ is a collection of unit tests that together prove that a function behaves as it’s supposed to, within the full range of situations you expect it to handle. A good test case considers all the possible kinds of input a function could receive and includes tests to represent each of these situations.

💚211 To write a test case for a function, import the unittest module and the function you want to test. Then create a class that inherits from unittest.TestCase, and write a series of methods to test different aspects of your function’s behavior.
