Performance testing is a vital part of the QA process for making a successful web application product. JMeter is one of the valuable tools for performance testing as it helps to count the user load your application can handle. JMeter is a Java-based application that one can use to measure the performance of various types of services.
JMeter can be used to perform load testing & stress testing for web applications and there are multiple steps involved.
- Step-1: Thread Group → Create a new Thread group from the JMeter application under threads (users)
- Step-2: Once Thread Group is created, add parameters like - Number of threads, ramp-up period, and loop count
- Step-3: Add JMeter elements like HTTP request default.
- Step-4: Execute your test case and analyze the results
For analysis of the report, you can consider "throughput" which is the ability of a server to handle the load.
Note:- Throughput is directly proportional to server performance.
Another parameter for measuring performance is deviation. The smaller the deviation, the better the performance.
