Measuring Test Effectiveness: How Good is Your Testing?

Rick Craig, Software Quality Engineering

Every year companies around the world spend vast sums of money testing software, yet many have no idea of the effectiveness of this effort. Some use flawed metrics, while others find the measurement problems too hard to even attempt. Rick Craig dissects some of the more commonly used measures of test effectiveness and discusses their pros and cons. From this list of measures, including defect removal efficiency, code coverage, and functional coverage, learn a practical and usable (if still imperfect) set of metrics that every organization needs to quantify its test effectiveness.
