jMeter-Performance Testing Tool

Introduction:

Apache JMeter is a 100% pure Java desktop application designed to load test functional behavior and measure performance. It was originally designed for testing Web Applications but has since expanded to other test functions. Apache JMeter may be used to test performance both on static and dynamic resources (files, Servlets, Perl scripts, Java Objects, Data Bases and Queries, FTP Servers and more). It can be used to simulate a heavy load on a server, network or object to test its strength or to analyze overall performance under different load types. You can use it to make a graphical analysis of performance or to test your server/script/object behavior under heavy concurrent load.

Features:

Apache JMeter features include:

• Ability to load and performance test many different server/protocol types:
• Web - HTTP, HTTPS
• SOAP / REST
• FTP
• Database via JDBC
• LDAP
• Message-oriented middleware (MOM) via JMS
• Mail - SMTP(S), POP3(S) and IMAP(S)
• Native commands or shell scripts
• TCP
• Complete portability and 100% Java purity.
• Full multithreading framework allows concurrent sampling by many threads and simultaneous sampling of different functions by separate thread groups.
• Careful GUI design allows faster Test Plan building and debugging.
• Caching and offline analysis/replaying of test results.
• Highly Extensible core:
• Pluggable Samplers allow unlimited testing capabilities.
• Several load statistics may be chosen with pluggable timers.
• Many advanced plugins are available to generate final report of jmeter.

Advantages & Disadvantages:

1.  It’s easy to use and GUI are very user friendly, which helps in executing and recording application sessions.
2.  It is open source. So, you can modify or change or add new features.
3.  Apart from above two reasons, the excellent benefit is that it is free. So, no license cost.
4.  It’s pure Java tool, which allows to execute this tool in any platform (i.e. platform independent)
5. It’s have many configuration mechanism like Http Request, FTP Request, java request, SOAP Request etc.
6. This tool mainly used for performance testing (load, stress)
7. It’s used only for web based application not windows base application.
8. If you are using it for a big project, then no guarantee of support or further enhancements.

Conclusion:
Need to test your web services, database, FTP- or web server? Both performance and functional testing? We can easily use JMeter. It is free, very intuitive and has all the possibilities you need to automate your work. Another big advantage of JMeter: open source tool.You can download the source and make modifications to it if you like. Also direct contact with the developers through a mailing list is very handy.
