How to conduct JMeter stress testing?

The steps for conducting JMeter stress testing are as follows:

1. Install JMeter: Download and install the JMeter software, ensuring that the Java environment is already installed on the system.
2. To create a test plan: Open JMeter, create a new test plan. Right-click on the test plan, select “Add” -> “Thread Group”, and set parameters such as concurrent users, loop count, and delay time in the thread group.
3. Add Sampler: To add a Sampler under the Thread Group, which can be an HTTP request, FTP request, or any other type of request. Choose the appropriate Sampler to simulate real user behavior.
4. Add assertions: Add assertions under the Sampler to verify if the response of the request meets the expectations. Assertions can check the content, response time, response code, and more.
5. Add listeners: Add listeners under the Sampler to collect and analyze test results. Commonly used listeners include Aggregate Report, Graph Results, View Results Tree, etc.
6. Configure thread group properties: Set attributes for the thread group, such as start time, stop time, duration, etc.
7. Configure JMeter settings: Set up options in JMeter such as thread count, ramp-up time, and loop count.
8. Run stress test: After saving the test plan, click the “Run” button to start executing the stress test. JMeter will simulate concurrent users sending requests and monitor the system’s performance metrics.
9. Analyze test results: After completing the test, review the test results in the listener to analyze indicators such as response time, throughput, error rate, etc., identify performance bottlenecks, and optimize them.
10. Optimize the testing plan by analyzing the test results, such as adjusting the number of concurrent users, increasing the number of threads, and changing the order of requests.

By following the steps above, you can conduct stress testing using JMeter, and obtain performance metrics and optimization suggestions for the system.
