I am currently using JMETER with plugin for Selenium Web Driver Sampler. Why is this happening? any solution I can use so that I can use implicit wait, explicit wait, and fluent wait?

Here is my code

I would like to create a JMeter test setup with important sampling and test variation parameters entirely controlled by csv-Files (i.e. not modifying the JMX-File). It should be run with maven. Ideas is as follows: sources.csv contains

Running a Gitlab project that uses a Docker image I created.

Problem: Gitlab job execution log shows that image is not being pulled. Here is the .gitlab-ci.yml file, with the company stuff removed:

I have created a JMeter script with 2 Thread groups. One keeps Putting multiples messages on an IBM MQ queue1 and then still at runtime, another one Gets and consumes the responses to each of these messages from another IBM MQ queue2.

The purpose is to generate load and measure the response times for all messages. For this goal, in order to synchronize the threads, I am using the Inter Thread Communication Plugin to pass the JMScorrelationID of each message from threads operating on queue1 (producers) to threads operation on queue2 (consumers). To do this I use JSR223 samplers with groovy code and these two libraries:

I would like to remove the test results during the ramp-up and ramp-down periods. This will help me to get test results during constant workloads. Also, it will remove outliers during the ramping time.

The solution shall be integrated with the JMeter script (JMX) itself. Removing the test results from the test result files (jtl,csv,xml) adds some extra work.

Synthesis Report plugin could help to a certain extent. But it needs manual intervention and has limited reporting capability. Synthesis Report is a mix between Summary Report and Aggregate Report:

I am using Jmeter 5.2.1 along with Concurrency Thread Group with ${__tstFeedback(ThroughputShapingTimer,1,10,10)} in combination with the Throughput Shaping Timer to dynamically change the target throughput throughout the test duration.

The Test Plan consists of a Thread group having a Module Controller and the ThroughputShapingTimer underneath it. The module controller controls a Test Fragment which contains the test logic.

I am encountering an issue at the end of the test where most of the time, a few last samplers result in a "java.net.SocketException: Socket closed" exception. This happens regardless if I have a ramp-down to 0 at the end of the test or not.

By contrast, if I use the same script with the same setup but just control it from a normal Thread Group, then all of the samplers complete successfully at the end of the script without issues.

Here are some screenshots of my setup:

Full error text from the sampler:

Referring to the JMeter Plugin Concurrency Thread Group documentation.

The Configurable Properties Section has two sub-topic with the same name. dynamictg.propertiescaching_validity:

The default value in the two sections is 20ms and 10ms.

Is this referring to same property or there is a typo in the property naming?

I am trying to use JMeter Throughput Shaping Timer on a JMeter distributed environment. JMeter master was configured with the JMeter Maven plugin. I have added the required plugins on the pom.xml and JMeter slave nodes. I double-checked my plugin versions on both sides and can confirm those versions are similar.

JMeter master runs with below dependencies list

From https://jmeter-plugins.org/?search=jpgc-casutg

I downloaded Maven Artifact: kg.apc:jmeter-plugins-casutg:2.9 which has Concurrency Thread Group.

1. Then I copied jmeter-plugins-cmn-jmeter-0.6 to Lib folder of Jmeter.
2. Also copied jmeter-plugins-casutg-2.9 to ext folder in Jmeter.

Then I restarted Jmeter and tried to add thread group but the Concurrency Thread Group option is not there .
