Test effort estimate
Estimate tester days and calendar time for a test cycle or release.
Quality & testingHow it's worked out
- Hours = (design cases × design minutes + execution cases × minutes × cycles × (1 + overhead)) ÷ 60. Tester-days = hours ÷ productive hours
- Steady productivity; overhead covers retest and defect logging
NoteUse your own measured minutes per test case; they vary widely with domain and test data. Add time for environment set-up and test data if it is not in the overhead.
