"You can't improve what you don't measure" - this saying is rightfully true for the world of software quality assurance. Quality Assurance (QA) metrics are used to estimate the progress and outcome of test results. Through metrics, it is easy to track the status of QA activities, measure team efficiency, and optimize processes.
Quality is the true measure of product success. Poor user experience or application performance negates any advantages you achieve in delivery speed or production cost. Put simply, if it does not work, it is not worth producing.
It is, therefore, critical to our product success that we can accurately measure and track test results to ensure our testing is delivering against our business goals. Understanding software quality metrics, especially in automated testing, helps us identify what is working well and what needs improvement.
