Test Velocity
01 Definition
Test Velocity meaning: How many experiments a team runs in a given period, often per month or quarter.
Test velocity measures the rate at which a team launches experiments, such as tests per month. Higher velocity means more chances to learn and improve, provided each test is well designed. Volume alone does not guarantee gains; underpowered or careless tests raise activity without producing trustworthy wins.

Why it matters
How Test Velocity fits the work
Test velocity reflects how fast a program can learn, since more valid experiments create more opportunities to find changes that help.
In context
The team raised its test velocity from two experiments a month to eight, giving it far more chances to find improvements without lowering test quality.
Practical note
Chasing velocity can tempt teams to cut samples short or skip good hypotheses, which produces noise. Pair velocity with test quality and adequate power to keep the learning real.
