What is JMeter
JMeter, short for Apache JMeter, is an open-source software
application designed for performance testing and load testing of web
applications. It was developed by the Apache Software Foundation and has gained
popularity as a powerful tool for assessing the performance, reliability, and
scalability of web services and servers.
Key Features of JMeter:
Testing: JMeter allows testers to simulate real-world scenarios by creating
virtual users and generating requests to test the performance of web applications
under various load conditions.
Testing: With JMeter, testers can apply heavy loads to web servers and
applications to determine their capabilities and identify potential
Testing: Apart from performance testing, JMeter also supports functional
testing by enabling testers to create and execute test scripts to verify the
correctness of web application functionality.
Support: JMeter supports various protocols such as HTTP, HTTPS, FTP, JDBC,
SOAP, and others, making it versatile for testing different types of
applications and services.
Testing: JMeter supports distributed testing, allowing multiple JMeter
instances to work together, which is particularly useful for load testing
Testers can use assertions in JMeter to verify the responses received from the
server, ensuring that the application meets the expected criteria.
and Reporting: JMeter provides graphical representations and comprehensive
reporting of test results, making it easier for testers to analyze performance

How JMeter Works:
Plan Creation: Testers create a test plan using JMeter's graphical user
interface (GUI) or by editing the test plan XML file directly. The test plan
defines the structure of the test, including the number of threads (virtual
users), loop count, and other configuration settings.
Groups: Testers define thread groups within the test plan, representing
different sets of virtual users and their behavior. Each thread group simulates
user actions such as logging in, browsing pages, submitting forms, etc.
Within each thread group, testers add samplers to generate requests to the web
application or server. Samplers represent different types of requests, such as
HTTP requests, database queries, or SOAP requests.
Elements: Testers can add configuration elements to modify the behavior of
samplers or provide additional data for testing purposes. Examples include HTTP
cookies, HTTP headers, and user-defined variables.
and Listeners: Testers can add assertions to check the responses received
from the server, ensuring that the application behaves as expected.
Additionally, listeners capture test results and display them in various
formats, such as graphs and tables.
the Test: Once the test plan is set up, testers run the test, and JMeter
starts sending requests to the web application or server, simulating the
behavior of virtual users under the specified load.
Results: After the test is complete, testers analyze the results using
JMeter's built-in listeners or by exporting the data for further analysis. The
test results help identify performance bottlenecks and potential areas for
JMeter is a powerful and versatile open-source tool used for
performance testing, load testing, and functional testing of web applications
and services. Its user-friendly interface, support for multiple protocols, and
extensive reporting capabilities make it a valuable asset for assessing the
performance and reliability of web systems. With JMeter, testers can ensure
that their web applications can handle real-world user loads and provide a
seamless user experience.
The Apache JMeterTM is unadulterated Java open source programming, which was first evolved by Stefano Mazzocchi of the Apache Software Foundation, intended to stack test utilitarian way of behaving and measure execution. You can utilize JMeter to dissect and gauge the exhibition of web application or different administrations. Execution Testing implies testing a web application against weighty burden, various and simultaneous client traffic. JMeter initially is utilized for testing Web Application or FTP application. These days, it is utilized for a practical test, data set server testOpen source permit: JMeter is thoroughly free, permits designer utilize the source code for the turn of events
Well disposed GUI: JMeter is very simple to utilize and doesn't carve out opportunity to get to know itStage free: JMeter is 100 percent unadulterated Java work area application. So it can run on different stagesFull multithreading structure. JMeter permits simultaneous and concurrent examining of various capabilities by a different string bunchImagine Test Result: Test result can be shown in an alternate organization, for example, outline, table, tree and log recordSimple establishment: You duplicate and run the *.bat document to run JMeter. No establishment required.Exceptionally Extensible: You can compose your own tests. JMeter additionally upholds representation modules permit you to broaden your testingNumerous testing procedure: JMeter upholds many testing techniques, for example, Load Testing, Distributed Testing, and Functional Testing.Recreation: JMeter can mimic various clients with simultaneous strings, make a weighty burden against web application under test
Support multi-convention: JMeter doesn't just help web application testing yet in addition assess data set server execution. All fundamental conventions like HTTP, JDBC, LDAP, SOAP, JMS, and FTP are upheld by JMeterRecord and Playback - Record the client movement on the program and mimic them in a web application utilizing JMeter
Test: Jmeter can be coordinated with Bean Shell and Selenium for mechanized testing.How does JMeter functionThe fundamental work process of JMeter as displayed in the figures underneathJMeter reproduces a gathering of clients sending solicitations to an objective server, and return measurements data of target server through graphical diagramsIt's not plausible to orchestrate 100 individuals with PC and web access at the same time getting to google.com Think of the foundation prerequisite when you test for 10000 clients (a modest number for a website like google). Thus you really want a product instrument like JMeter that will mimic genuine client ways of behaving and execution/load test your site.
