Count meaningful behaviours
Use requirements or user paths, not raw lines of code, as the unit of coverage.

How it works
Separate tested from untested
The calculator measures which behaviours have evidence, then highlights the remaining gap.
Weight critical paths
Untested payment, access, data, or core-workflow paths reduce the release-readiness score more heavily.

Frequently asked questions
Is this the same as line coverage?
No. Line coverage measures executed code. This tool measures whether important expected behaviours have meaningful verification.
What is a critical behaviour?
A behaviour whose failure would block the core job, expose data, cause loss, or make a release unsafe.
What percentage is enough?
There is no universal number. Start by making all critical behaviours verifiable, then use the score to prioritise the remaining release risk.
