performance testing using jmeter

performance testing, the thread group is a required element. This element can be used to simulate multiple users to perform stress tests on the server. You can even preset the testing time, which is a detailed display of the thread group. On the other hand, the same test plan can be extended to include functional or regression

Performance testing is an important part of any distributed or Web application test plan. Performance evaluations in the planning and development cycle ensure that applications delivered to customers meet customer requirements for high load, availability, and scalability. Determining the load limit of the software in advance can help with proper system configurat
