Testing / Apache JMeter Interview questions

What is the HTTP(S) Test Script Recorder?

The HTTP(S) Test Script Recorder is a built-in proxy server that JMeter runs locally; when a browser is configured to route its traffic through it, every request the browser makes gets captured and automatically added to a test plan as HTTP samplers.

This is commonly used to quickly bootstrap a test plan by manually clicking through a real user journey in a browser, rather than hand-writing every HTTP sampler and its parameters from scratch.

Recorded scripts typically need cleanup afterward - removing unnecessary requests (like static assets), adding correlation for dynamic values, and parameterizing hardcoded data - since a raw recording just replays exactly what one specific browser session did, verbatim.

The Test Script Recorder works by acting as a:
A recorded script typically needs:
