You can get BlazeMeter's Google Chrome Plugin directly from the Chrome Web Store. Users do not have to install JMeter or any other software in order to record and run a performance test. Users can also edit the requests the browser will include or download the generated script and use JMeter locally - all via the Chrome extension. Using basic commands like start, stop, pause, edit or upload, users can easily record any HTTP/S requests recorded by the browser as well as offering advanced filtering options, like allowing filter requests based on regular expressions. There, the script can be executed with a single click or users can opt to download the generated JMeter script (.jmx file) locally. BlazeMeter's Chrome extension allows users to record all browser activity directly from their browser without the need for any additional software.īlazeMeter's Chrome extension records all of the HTTP/S requests made through the user's browser, creates a JMeter script and automatically uploads it to BlazeMeter's platform. To do this, right-click on Test Plan -> Add -> Listener -> Backend Listener:NEW YORK, NY-(Marketwired - Oct 8, 2013) - BlazeMeter today announced the release of its Google Chrome extension as the newest addition to their performance testing platform for developers.But before that, to follow our test in real time, we will add the Backend Listener element to enable live monitoring of the progress of the test with Grafana ( ).So, let's use best practices directly and run our test from the command line in CLI mode (also called Non-GUI mode in JMeter).NoteĪn easy and quick solution to monitor JMeter can be to use the Servers Performance Monitoring plugin from the JMeter Plugins ( ). Note that this is not specific to JMeter but should be done regardless of the tool you use. This ensures that if we get bad response times, the cause is the application being tested and not JMeter. When load testing, it is advisable to monitor the injectors (servers where JMeter runs) at least during the first test at full load to validate the correct behavior of the injectors.We could run our load test directly from the JMeter GUI, but this is not recommended as it would not be optimal for performances of injection (although, in our case, with only 10 users, it shouldn't be a problem).This point will be discussed deeply in Chapter 2, JMeter Overview. Several strategies for setting the load test exists. By the end of this book, you'll know all that's needed to perform comprehensive load testing on your applications by using all the best practices and features of JMeter.įigure 1.27: Load test parameters Caution You'll discover ways to use the eco-system of JMeter to integrate new protocols, enrich its monitoring, and leverage its power through the use of the cloud. Finally, you'll see how to integrate JMeter into the DevOps approach and create professional reports. You'll also explore the different protocols offered by JMeter through various real-world examples. You'll learn the best practices that you must follow while designing test cases. This book is written by JMeter developers and begins by discussing the whole process, including recording a script, setting it up, and launching it, enabling you to almost immediately start load testing. By leveraging the features and capabilities of JMeter, you can perform extensive load testing and fix issues in your application before they become problematic. One popular open source tool for load testing is JMeter. Load tests help identify the maximum number of requests a software system can handle.
