The document discusses various metrics that can be collected during software testing. It describes metrics for the requirements phase like requirement stability index and requirements leakage index. For the test design phase, it discusses metrics like test case preparation productivity. Metrics for the test execution phase include test case pass percentage and test case execution percentage. Defect metrics covered are defect summary, defect discovery rate, defect severity, defect density, and defect rejection ratio. Formulas for calculating these metrics are provided along with descriptions of what each metric measures.
