High code complexity, often indicated by deeply nested structures, excessive branching, and lack of modularity, correlates directly with increased maintenance difficulty. For example, highly complex code requires more effort to understand, debug, and modify, leading to longer maintenance cycles and increased risk of introducing new errors during modifications. Within the context of the fifth round of NFR testing, high code complexity may necessitate refactoring or code simplification to improve maintainability and reduce long-term costs. Tools like SonarQube can provide quantifiable metrics for code complexity, facilitating data-driven decisions regarding code improvements.
-
Modularity
Modularity evaluates the degree to which a system is composed of independent, interchangeable components. A highly modular system is easier to maintain because changes within one module are less likely to affect other parts of the system. For instance, a modular e-commerce platform allows developers to update the payment gateway module without impacting the product catalog or user account management modules. The fifth round of NFR testing assesses modularity to identify areas where tighter coupling between components increases maintenance complexity. Improving modularity reduces the risk of unintended consequences during maintenance and facilitates parallel development efforts.
-
Testability
Testability refers to the ease with which individual components and the entire system can be tested effectively. High testability simplifies regression testing, facilitates rapid identification of defects, and reduces the cost of quality assurance. For example, a system with well-defined interfaces and comprehensive unit tests allows for efficient and targeted testing of individual components. Within the fifth round of NFR testing, assessing testability helps identify areas where improving test coverage or implementing automated testing strategies can enhance maintainability and reduce the risk of introducing regressions during future modifications.
