Agile development practices (2)

1. The higher the test, the higher the quality. The test must be effective. If the test fails to detect any problems, they may not have conducted a valid test.

2. There are two ways to design software. One is to make the design as simple as possible without obvious defects. Another way is to design as complex as possible without obvious defects.

3. Make the functions of the class as concentrated as possible, and make the components as small as possible. Avoid creating large classes or components, or create a wide variety of classes.

The introduction of automated testing tools in various development processes will greatly improve the code quality.
