Learn JMETER from Scratch on Live Apps -Performance Testing

Boost your jmeter learning from scratch by applying expert video viewing tips, including selecting 720p or 1080p, enabling full screen, and adjusting playback speed to 1.25–1.5 with clear audio.

Record user actions in the browser with the HTTP Test Script Recorder to auto generate a JMeter test plan, then run with a load of 200–300 users to measure performance.

Record actions in Firefox by configuring a proxy on a specific port, install JMeter's certificate for HTTPS, then playback and replay captured requests in a test plan.

Record browser actions in Chrome with the BlazeMeter extension to generate a .jmx script for JMeter and import it into JMeter for load testing.

Learn to use the thread group in JMeter to run a single scenario with multiple users, enabling load testing by executing the same flow with a configurable number of threads.

Apply load on live apps with a thread group using 50 users, ramp up over five seconds, set loop count or forever, and monitor results with listeners.

Learn how JMeter listeners track test execution and capture load results, and use view results tree, aggregate report, and graph results to monitor performance.

Learn how to interpret JMeter's aggregate report: analyze samples, average, min, max, error rate, and throughput per second for reserve.php, and benchmark server capability for load testing.

Identify and compare different listeners in JMeter to measure performance metrics, interpret percentile response times (90/95/99), throughput, and deviation, and visualize results with aggregate, view results tree, and graph results.

Learn to extend JMeter with plugins to simulate real-time load using concurrency and ultimate thread groups, installing the plugin manager, and configuring advanced thread group properties.

Explore concurrency thread group and ultimate thread group usage in JMeter, configuring ramp up time, step counts, and hold target rate to simulate real-time user load.

Learn how the HTTP cookie manager handles cookies in secured, cookie-based apps while recording login/logout flows in JMeter; explore main samplers, sub-samplers, and response verification to avoid false positives.

Learn how the HTTP cookie manager in JMeter stores and reuses cookies like a browser to maintain a session during login and across subsequent requests.

Learn to validate JMeter tests by using response, size, and duration assertions to ensure pass/fail status, verify codes, headers, and messages across live apps.

Learn how to use jmeter assertions, including size and duration assertions, to validate response bytes and load times for authenticate requests, demonstrating how to set thresholds and interpret results.

Create http request samplers using the WebTours sample application, install on Windows, start the Apache server with StartServer.bat, and access 1080/webTours to practice JMETER load testing.

Discover how controllers organize JMeter scripts by grouping samplers into modules like login, flight search, and reservation; use transaction and recording controllers to measure module performance and throughput.

Master JMeter transaction and simple controllers by wrapping samplers into modules, and reuse code with module controllers; learn to interpret aggregate reports and throughput for login, flight search, and reservation.

Learn how the interleave controller selects one sampler per iteration from multiple samplers, with practical examples, and compare its use with runtime, random, if and loop controllers in JMeter tests.

Learn how to use the runtime, random, and interleave controllers in JMeter to rigorously load test live apps, controlling execution time and sampling order for precise performance insights.

Learn how if and loop controllers drive stress testing by executing samplers on conditions and looping a set number of times, with runtime, while, and random controllers.

Learn how timers control thread delays in JMeter to mimic real-time load, using constant, gaussian random, and poisson random timers to insert sleeps between requests.

Explore the constant throughput timer and how it governs request flow to meet a target throughput. Use four servers and real-world examples to illustrate pass mode and throughput calculations.

Learn how to use the regular expression extractor in JMeter to dynamically capture username and password from the login response, then feed them into subsequent requests via post processor.

Learn to extract dynamic usernames in flight search app using regex extractors in JMeter. Build extractors with dot plus, grouping, and debug sampler to verify response body values before authenticating.

Learn to extract username and password from a login response with one regular expression extractor using groups g0, g1, and g2.

Learn to create HTTP request samplers in JMeter from scratch without recording by constructing POST requests and form data via network inspection, and add assertions with a results tree.

Learn to data drive your JMeter scripts from external csv files using csv data set config, enabling unique user registrations via thread groups.
