Since JMeter 5.0 testers have an option of generating additional charts as a part of the report dashboard. Did you know about that? Thanks to this you can visualize a specified variable over time of a test like below: Let’s check how to do it. What can I visualize? As already mentioned you..
In the last post I wrote about sending a simple text message to the Oracle’s AQ queue. This time let’s have a look at a bit different case of having an object marshalled to JSON and then sent to the queue as a byte message. And yes, we still will be sending the message to..
In this post I will tackle a task of sending a simple text JMS message to a Oracle AQ queue using JMeter. Next week, I will follow that with a description of what to do to send a JMS byte message in JSON format. Stay tuned for that one. There are two samplers in JMeter..
A spike test is a type of performance test where we simulate a sudden and considerable change in workload. How the simulated workload looks like in a spike test Check out an example of the workload below: apply some low load to the system first to make sure that everything works OK and system..
In the last post I’ve written how you can quickly generate a chart that compares results of two JMeter tests. Now, let’s add some more info to this graph. This is where we finished the last time and what we will be improving today: Difference in number of samples between two runs ..
Today I want to cover a topic of how to compare results of two test runs in JMeter. As there is nothing provided out of the box solution, I have seen a few solutions in my career as performance tester. The one presented here I like the most. A goal behind the solution presented..
In one of the previous posts I presented an improved version of JMeter’s Time vs Threads chart. Now, it’s time to tackle another gap in JMeter’s dashboard graphs: transactions per minute. You may ask why I need it, since there is a similar chart already available – transactions per second. I have to admit..
“I have found a deadlock in the database” – I said few years ago to a product owner on the customer’s side. “What!? Really?” – She said anxiously as we were close to the release date. “Yes, when the processes are at certain stage, the deadlock appears. As a result one of the processes fails” –..
Few years ago, JMeter has added a great html report that could be generated after a test run. Even though the report is constantly improving, it’s still far from being perfect. I like the variety of graphs a lot, however, in my opinion, there is an issue with the graphs being only available with a..
This time I want to share with you a script that can be used to parse the JMeter’s .jtl results file removing some not needed stuff from it. When such script might be useful? The script was already used in these situations: you have a huge results .jtl file – I’m talking about gigabytes in..
