Performance test-jmeter: installation/basic use

1. Understand jmeter

Official website-Apache JMeter-Apache JMeter™

JMeter is an open source performance testing tool, mainly used to simulate a large number of users concurrently accessing the target server to evaluate the performance and stability of the server.

JMeter can perform the following tasks
serial number	use	describe
1	Performance Testing	By simulating multiple users making requests to the server at the same time, you can test the server's response time, throughput, number of concurrent users and other indicators under different loads.
2	load test	Test the server's performance limits by gradually increasing user load to determine the server's stability and reliability under high load conditions.
3	pressure test	Through continuous high load testing, the stability and performance of the server under long-term operation are evaluated.
4	function test	You can simulate user operations in actual applications, such as clicking buttons, filling out forms, etc., to check whether the application functions normally.
5	API testing	You can simulate requests to web services or RESTful APIs and verify whether the response results are as expected.
6	Distributed testing	Test by spreading the load across multiple machines to simulate more realistic user behavior and load conditions.
7	Monitoring testing	The server's resource usage, such as CPU, memory, disk IO, etc., can be monitored to detect server bottlenecks and performance issues.
JMeter is a powerful tool that helps developers and testers perform performance and load testing and evaluate the performance and stability of an application or server.

Record 1. Does installing JMeter require a maven environment?

Installing JMeter does not require a Maven environment. JMeter is a standalone Java application that can be downloaded and installed directly from the official website. However, if you want to use Maven for project management and build, you can introduce JMeter into the Maven project and use Maven to manage JMeter's related dependencies and build process.
