Effective software testing strategies rely on a combination of functional and non-functional testing to ensure robust application performance and user satisfaction. Functional testing focuses on verifying that an application meets specified requirements through a variety of methods, such as unit, integration, and user acceptance testing, emphasizing the correct execution of processes. Non-functional testing evaluates aspects like performance, usability, and security, which contribute to the overall user experience but are not directly tied to specific functionalities. While functional tests are often prioritized due to their direct impact on usability and the relatively lower cost and time required for execution, non-functional tests are equally critical, particularly for identifying issues at scale. A balanced approach involving both testing types, integrated into a continuous integration and continuous deployment (CI/CD) pipeline, enhances the reliability and efficiency of software development, addressing both the accuracy and quality of code execution.
