🌟 Core Components of JMeter

•  Thread Group: In JMeter, the thread group defines the number of users and their interaction pace. It’s the starting point of any test plan in JMeter.
•    Samplers: Samplers in JMeter simulate different types of requests, like HTTP, FTP, or JDBC. These requests allow JMeter to measure response time, data size, and server behavior.
•   Timers: Timers in JMeter introduce delays between user requests to simulate real-world user interactions. Common timers in JMeter include Constant Timer, Uniform Random Timer, and Gaussian Timer.
•  Assertions: Assertions validate server responses in JMeter to ensure expected results. For example, Response Assertions or Size Assertions are widely used to verify output.
•    Processors: JMeter includes Pre-processors and Post-processors to modify requests or analyze responses dynamically.
