Classquality

Classquality is a term that denotes the overall quality of a class in object‑oriented programming. It is used by developers and software analysts to assess how well a class fulfills the principles of clean, maintainable design, such as single responsibility, low coupling, high cohesion, and clear encapsulation. The measure is typically expressed through a combination of quantitative metrics—like lines of code, cyclomatic complexity, coupling‑between‑objects, and depth of inheritance—and qualitative judgments about design intent.

The concept emerged in the early 2000s as part of the broader software quality assurance movement. In academic literature, classquality has been studied in relation to defect density, code reusability, and maintenance effort. Practitioners employ static analysis tools that compute classquality scores during continuous integration to flag class design erosion over time. Some frameworks provide a predefined threshold; classes scoring below this threshold are recommended for refactoring or decomposition.

Metrics used to calculate classquality are often weighted to reflect project-specific priorities. For example, a safety‑critical system might weight coupling and cohesion more heavily than code size, whereas a rapidly evolving startup product might emphasize maintainability. In addition to automated tools, code review sessions are considered essential for interpreting the raw scores, ensuring that subjective design trade‑offs are captured.

Classquality has become a component of many code quality dashboards, helping teams achieve predictable delivery cycles, reduce technical debt, and improve overall software reliability.
