Four rules for simple design

1. Run All tests

Tightly coupled code is difficult to write tests, using tools such as dependency injection, interfaces, and abstractions to minimize coupling

2. Non-repeatable

3. Expressing the programmer's intentions

The obvious class name and function name can help others to shorten the time to understand the code and reduce maintenance costs; Short classes and functions are often easy to name, easy to write, and easy to understand

4. Minimizing the number of classes and methods
