Upholding coding best practices ensures our osCommerce projects are efficient, maintainable, and scalable. This involves following established guidelines for clear, optimized code, facilitating collaboration and minimizing errors.

Unit testing involves testing individual components or units of code in isolation to ensure they function correctly. This process helps identify and fix bugs early in the development cycle, improving overall code quality and reducing the likelihood of regressions. By writing automated tests for each unit of code, developers can verify its behavior under various conditions, enhancing the reliability and maintainability of the software.

Code review practices involve systematically examining code changes made by developers to ensure they meet quality standards and adhere to best practices. This process helps identify potential issues, improve code readability, and share knowledge among team members. By conducting regular code reviews, teams can catch bugs early, maintain code consistency, and promote collaboration and learning within the development team.

Code quality metrics are quantitative measures used to assess the quality of software code. These metrics evaluate various aspects of code, such as complexity, readability, maintainability, and reliability. Common code quality metrics include cyclomatic complexity, code duplication, code coverage, and maintainability index.

By analyzing code quality metrics, developers can identify areas for improvement, prioritize refactoring efforts, and ensure that code meets established quality standards. These metrics provide valuable insights into the overall health and maintainability of a codebase, helping teams make informed decisions to enhance software quality and reduce technical debt.
