[quality] code quality evaluation standard

Today, let's think about how to evaluate code quality ？

Seven standards recognized and recognized by the industry ：

Maintainability （maintainability）、 Readability （readability）、 Extensibility （extensibility）、 flexibility （flexibility）、 Conciseness （simplicity）、 Reusability （reusability）、 ...Testability （testability）.

One 、 Maintainability

Not because of new features feature or bugfix introduce bug, It can efficiently complete the development of new functions and bugfix, The code is easy to maintain , Low maintenance costs and risks

Two 、 Readability

Code doesn't just need to follow the syntax rules of the programming language , You also need to follow the team's coding conventions , Students in the team need to be able to easily understand each other's code , For example, whether it meets the coding specification 、 Is the name meaningful 、 Is the note exhaustive 、 Is the function the right length 、 Whether the module division is clear 、 Whether it meets the requirements of high cohesion and low coupling, etc , Generally, teams need to rely on coding specifications to constrain , Pass code review To detect readability , Readable code , be responsible for review My classmates read the code faster , There's no doubt to go straight to the code problem , conversely , Code questions are too many to understand ,review The effect is greatly reduced , therefore , Code readability can greatly enhance code review effect , Reduce risk .

3、 ... and 、 Extensibility

Modify the inner closure , Opening up and expansion , Need to meet “ High cohesion and low coupling ” Code design principles , The extension of new functions will not destroy the modification of internal code and introduce unnecessary risks , But through extended design , Ensure that the new function code is relatively independent , Does not affect the original code logic ; Try not to modify the original code , And realize new functions .

Four 、 Reusability

Reusability refers to the degree of code reusability , Whether the new function development can reuse the original code , This requires that code module design should not be mixed with business logic , Reduce code writing and changes , Yield twice the result with half the effort .

5、 ... and 、 flexibility

seeing the name of a thing one thinks of its function , Is to write a very clever code , To meet the scalability , And meet the reusability , Affect existing code as little as possible , Write the least code , You can realize the expansion of new functions , Maintaining the status quo , Call it magic .

6、 ... and 、 Conciseness

There is one that states the design principles ：KISS（“Keep It Simple,Stupid”） Keep your code simple , This requires a deep knowledge of code algorithm , Master moves , A deadly move , There is no false move . however , Conciseness may run counter to readability , Keep it simple , There is a need to ensure code readability , Need balance , It's not easy , Think deeply and act simply , Thick and thin hair .

7、 ... and 、 ...Testability

Code testability can reflect the level of code quality from the side , It is convenient to write unit test cases , The function development code is not changed completely , Instead, the risk of modification will converge within the controllable range .

So how to measure code quality ？ Welcome to discuss .
