Beginner LoadRunner Notes

1. Terminology

Throughput: Flow through the system under test per unit time, unit (b/s)

Server language: JSP (Java Server Pages)-tomcat ASP (Action Server pages)-lls PHP (hypertext Preprocessor)-apache

Concurrency: Multiple simultaneous operations

CTR: The number of HTTP requests that the client sends to the server in unit time (s)

Stability test (Reliability test): continuous operation of the system under test, to see the stability of the system operation, the general use of 24*7 way to make the system uninterrupted operation

Load test: Allows the tested system to run continuously within the tolerable pressure range to see the stability of the system

Stress testing: Continuously increases the pressure on the system until the system is crushed to test the maximum pressure that the system can withstand

2.LR is divided into: Visual User Generator, Controller, analysis

Script Builder: Record Debug Script scene controllers: Generate scenes with scripts, execute scenes, and monitor results in a scene analyzer: Analyzing monitoring metrics results

3. Process for performance testing using LR: Test plan-record test script-Create run scenario-run test-monitor scene-Analyze test results

4. Editing scripts include insert transaction (transaction), insert collection point (Rendezvous), insert Comment (comment), insert checkpoint, insert function, script Parameterization, association, and more

Note: 1. Transaction and rendezvous can be inserted at the same time, no order required; 2.rendezvous can only be inserted into the action section, User_init and User_end cannot be inserted in the collection point

5.controller: Components for designing and executing scenarios for performance testing

Key monitoring metrics: CPU utilization, available memory capacity, and the amount of CPU resources consumed by the service thread

Ramp up: Set policy for virtual user to stop

Start all vusers simultaneously stop all users at the same time
