⚪Jmeter
Apache JMeter is a Java-based stress test tools developed by Apache. For software to do the stress test, which was originally designed for testing Web applications, but later extended to other test areas. It can be used to test static and dynamic resources, such as static files, Java servlets, CGI scripts, Java objects, databases, FTP servers, and so on. JMeter can be used to great load to a server, or network objects in the simulation, testing and analysis of their strength from the overall performance under different load types. In addition, JMeter can do functional / regression testing for application by creating a script with the assertion to verify your program returns the results you expect. For maximum flexibility, JMeter allows the use of regular expressions to create assertion.
Apache jmeter can be used in the performance of static and dynamic resources (files, Servlet, Perl scripts, java objects, database and query, FTP server, etc.) for testing. It can be used on a server, or network subject to heavy load simulation test its strength or overall performance analysis types at different pressures. You can use it to do a graphical analysis of performance or in large concurrent load test your server / script / object.
⚪Jmeter major components
Jmeter create a performance test project engineering, configuration, and is composed of a series Jmeter each component.
This feature Jmeter to the performance test provides a very large degree of freedom as how to select, configure these components is completely free.
Because of its open source nature, Jmeter components very much, want to introduce them all is almost impossible, we need to understand their core components and ideas.
⚪Thread Group (thread group)
⚪Config Elements (Configuration element)
⚪Pre-Processors (preprocessor)
⚪Timer (timer)
⚪Assertions (assertion)
⚪Post-Processors (post processor)
⚪Listener (listeners)
⚪ assembly sequence
In the same scope, the implementation of the above components to follow a certain order, as follows:
