Health Score reference

Calculation

The Health Score is the average of four equally weighted factors, producing a value from 0 to 100.

Recency

Recently synced projects score highest. The factor receives full credit when the latest sync is no more than seven days old, falls linearly, and reaches zero at thirty days.

Momentum

Momentum compares additions with deletions. Positive net growth contributes to the factor, scaled by the proportion of additions that remain after deletions. A flat or shrinking suite receives zero for momentum.

Churn

Churn measures deletions as a proportion of recorded additions and deletions. Rates of ten percent or less receive full credit, rates of fifty percent or more receive zero, and values between them fall linearly.

Breadth

Breadth considers how tests are spread across files. Full credit currently requires at least three test files containing five or more tests each.

Labels and interpretation

Scores are labelled Excellent from 80, Good from 60, Fair from 40, and Needs Attention below 40.

The score is a heuristic for investigation. It does not measure assertion quality, production risk, or functional coverage by itself.
