Video description

If you want to get a real-time experience of load testing with the most popular open-source performance testing tool JMeter then this course is perfect for you. The course is designed to help you learn how to use JMeter without any prior knowledge of JMeter or performance testing.

The course starts with an introduction to JMeter, and then helps you install and configure JMeter on your machine. Next, you will learn to record and playback JMeter scripts, analyze the load with listeners, and understand the importance of the thread group in JMeter. Further, you will learn about assertions, controllers, and timers in JMeter and find out the importance of regular expression in JMeter with the help of a flight search application. As you move along, you will perform data-driven testing in JMeter, and handle dynamic responses. Moving ahead, you will perform JMeter validations in non-GUI mode, run tests on the slave machine from the client machine, and become familiar with the basics of BeanShell scripting. Finally, you will learn how to integrate Selenium with JMeter, get an overview of REST API load testing, and understand the importance of server monitoring.

By the end of this course, you will have developed the skills to design robust performance test cases in the JMeter tool and will be able to monitor the performance of an application with different load parameters.

What You Will Learn

  • Record application under test in JMeter with Firefox and Proxy
  • Create REST API test cases in JMeter
  • Put load on web applications and REST APIs and monitor the load
  • Use controllers to track the performance of applications
  • Become familiar with commands to run tests in non-GUI mode
  • Find out how to integrate Selenium with JMeter

Audience

This course is a valuable resource for manual and web service testers, who are looking to get into load testing. Non-programming testers will also find this course useful as prior knowledge of programming or load testing is not required to get started with this course.
