Introduction
- You should consider writing tests as your safety net. It will make you more confident in your work, allow you to refactor with confidence, and be certain that you are not breaking other parts of the system.
- A test suite is a must-have if you are porting a Python 2 code base to Python 3, as any guide will tell you, (https://docs.python.org/3/howto/pyporting.html#have-good-test-coverage).
- It is a good idea to write tests for the external APIs you depend on, if they don't have automated tests.
- One of the reasons pytest is a great choice for beginners is because it is easy to get started; write your tests using simple functions and assert statements.
