What are the various kinds of listeners in JMeter?
Performance testing is examining server responses in multiple formats before delivering them to the client. As a sampler component of JMeter is implemented, listeners give a graphical representation of data gathered by JMeter regarding those test cases. The user can view sampler results in the form of tables, graphs, trees, or plain text in a log file.
Listeners can be changed at any point during the test, including within the test plan. JMeter provides roughly 15 listeners, but the most commonly used ones are table, tree, and graph. In short, Listeners are used to storing the results of load testing execution in various formats, such as a table, tree, graph or any other appropriate format that may be given to the client. JMeter comes with a variety of built-in listeners, and many more can be added through plugins, depending on your needs. The following are a few of the inbuilt listeners: View Results in Table, Graph Results, Aggregate Report, Aggregate Graph, Response Time Graph and Assertion Results.
