Quality Assurance (QA) metrics serve as the compass guiding software development teams toward delivering superior products. These metrics go beyond mere bug counts, delving into various aspects of the testing process to evaluate efficacy, quality, and overall success. Understanding and utilizing these metrics effectively is pivotal in ensuring a robust testing strategy.
