Test Metrics can be used to measure test
coverage prior to software delivery. It provides a measure of the percentage of
the software tested at any point during testing.
It is calculated as follows:
Functional
Test Coverage = number of test requirements that are covered/total number of test requirements.
Types of Test metrics
Software
Release Metrics
The software is ready for release when:
1. It has been tested with a test suite that provides 100% functional coverage,
80% branch coverage, and 100% procedure coverage.
2. There are no level 1 or 2 severity defects.
3. The defect finding rate is less than 40 new defects per 1000 hours of testing
4. Stress testing, configuration testing, installation testing, Naïve user
testing, usability testing, and sanity testing have been completed
