Introduction to JMeter & How to View JMeter Test Results in Real-time?

What is JMeter?
The Apache JMeter is completely Java open-source software. It was first developed by Stefano Mazzocchi who was working for Apache Software Foundation, designed to load test functional behaviour and measure performance. You can use JMeter to measure the performance of a variety of services or web applications. Performance testing means testing a web application against concurrent & multiple user traffic and heavy loads. JMeter originally is used for testing FTP applications or Web Applications. These days it is used for database server tests, functional tests etc.How does JMeter work?
JMeter imitates a group of users. They will send requests to a targeted server and return statistics information of the target server through graphical diagrams & tables.Advantages of JMeter:
Some of the advantages of JMeter are as follows:Open Source License:
Friendly GUI:
The user takes less time to get familiar with it and it is really easy to use.
Platform Independent:
Full Multi-threading Framework:
It allows concurrent and synchronized sampling of different functions by a different thread group.
Visualize Test Results:
Test results can be shown in different formats like table, tree, chart and log file.
Easy Installation:
Highly Extensible:
Multiple Testing Strategy:
Simulation:
Support Multiple Protocols:

Record & Playback:
Script Test:
JMeter Summary Report Analysis in Real-time
The customary way to use JMeter is in Non-GUI mode (CLI). By running in CLI mode, users save resources and ensure their test results are reliable. Using the JMeter, GUI is meant only for development, debugging and test recording.The Problem Viewing JMeter Results File in Real-Time:
Though, running JMeter in CLI mode may bound users who want to understand what is going on in their test in real-time, as CLI mode stops incorporating listeners during the test run. Any listener you used to have in your test plan was probably Graphical User Interface mode-specific and don’t send anything to non-GUI mode.Nowadays, when users want to understand what is occurring in their test, they have to wait for the test to finish running. Then they take the sample.jtl file that their load test produced, open the JMeter GUI and add their preferred listener to the test plan. They can then load the sample.jtl file into the Listener and see the graph/reports.
