Apache jmeter domain names7/28/2023 You can also run the tests a specified period of time by checking the InfiniteĬheckboxes and entering the runtime in seconds in the Duration When the InfiniteĬheckbox is not checked, the test will perform the steps a Loop Count The thread group also controls how long the test will run by the value in Loop Count The Ramp-up periodĭefines how many seconds it will take before all threads have started. A thread group controls how many threads (users) are used when running the test and is the number of parallel tests that will be run at any given time. In the left pane and selecting Threads (Users) | Thread Group The first step is to add a thread group by right clicking on Test Plan To support your tests, you need to add a few building blocks. Understanding JMeter ScriptsĪfter opening JMeter, you start with an empty testing project. Inspired to take a closer look, I took JMeter out for a test spin. From the Internet, I found that JMeter users also had some testing issues, but in general, they were all quite glad to get away from LoadRunner. I first learned about JMeter while looking for solutions for my LoadRunner problems. Some fairly pricey solutions from software vendors can assist in this process (e.g., LoadRunner), but the good news is that the open source world has come up with some pretty compelling solutions of their own. Testing can mean a lot of things to a lot of people, but for me, it comes down to testing Internet applications and services when under high load, which usually means testing REST APIs or connecting to and stepping through various scenarios on a website. What I did discover was configuration errors in my Apache setup in the test environment. When I first started down this path, it did not take much to imagine that I might not have enough power on my laptop or that the test server could run out of connections – but none of that happened. Even if you know your website can handle a load of 30 users a second or that more than 500 users causes a small fire in the data center, the big question is: Will the next release work under the same load? Finding an answer to this question offers peace of mind when getting ready to put up a new version of your software live in the middle of the Christmas season.
