Code metrics, maintainability, and security
As developers, we rely on code metrics to evaluate the quality of a software system. These quantitative measures provide insights into various aspects of our code, such as complexity, maintainability, and security. By understanding these metrics, we can identify areas that may need improvement, ensuring that our code base remains manageable, secure, and efficient.
Understanding the metrics
Visual Studio allows us to generate a report containing a list of metrics, such as the following:
- Maintainability Index assesses how easy it is to maintain code, giving a score from 0 to 100, where higher scores indicate better maintainability. Ratings are color-coded: green (20-100) for good, yellow (10-19) for moderate, and red (0-9) for low.
- Cyclomatic Complexity measures a code’s structural complexity by counting its different flow paths. High complexity suggests more tests are needed for good coverage and lower maintainability...
