Think Time
// Definition
Pauses between user actions in a load test that simulate real reading, scrolling, or decision time. Without think time, a load script generates an unrealistic, machine-gun request pattern that doesn't match production traffic.

Load Testing
Verifying system behaviour under expected production load. Confirms the application meets performance targets at typical concurrent-user counts before release.
Concurrent Users
The number of users actively interacting with the system at the same moment. A primary input to load and stress test design.
Ramp-up Period
The duration over which virtual users gradually start hitting the system at the beginning of a load test. A short ramp-up can mimic a flash crowd; a longer one models steady traffic growth.
