Dynamically replacing Number of Threads parameter in a JMeter script

This is a simple shell script that replaces "Number of Threads" parameter in the original script, accepting it from the command line.

touch ./run_jmeter.sh
chmod +x ./run_jmeter.sh
And finally insert the code below into the file using your favorite editor.

#!/bin/bash
# Call this script with the Number of Threads parameter, e.g.: run_jmeter.sh 10
echo "Preparing JMeter script"
sed "s#<stringProp name=\"ThreadGroup.num_threads\">.*#<stringProp name=\"ThreadGroup.num_threads\">$1</stringProp>#" all_pages.jmx > ./all_pages_converted.jmx
echo "Running JMeter script with $1 Threads"
jmeter -n -t all_pages_converted.jmx -l ./perf_test_results.jtl

Integrating TestRail and Gitlab CI/CD

Perhaps you are using Gitlab CI/CD at your project. Every project requires some test cases for regression testing, and Gitlab actually provides this feature, but it’s only available in Ultimate version that is more expensive. TestRail is another popular platform for managing your test suite that provides way more extensive capabilities and options than Gitlab’s own test case management feature. So the chances are that you are still willing to use TestRail for your acceptance and regression testing efforts. Why not combining the best of two worlds — the flexibility of Gitlab CI/CD and rich test case management capabilities of TestRail? In the following example I’ll demonstrate how this goal could be achieved with ease. Let’s assume that we need to create a new Milestone in TestRail that contains two test runs — the one with Acceptance tests, and another one with Regression tests. The step in your .gitlab-ci.yml Gitlab configuration file would look like this: This step is reading C...

Switching between keyboard layouts in Openbox (Arch Linux)

Switching between two (or more) keyboard layouts in Openbox DE is a task that's quite easy to accomplish, although it might not be so obvious as in other desktop environments. This solution was tested on Arch Linux. You just need to edit this file (assuming you want to switch between English and Ukrainian Phonetic layouts with Alt-Shift): /etc/X11/xorg.conf.d/01-keyboard-layout.conf Section "InputClass" Identifier "keyboard-layout" Driver "evdev" MatchIsKeyboard "yes" Option "XkbLayout" "us,ua(phonetic)" Option "XkbModel" "pc105" Option "XkbOptions" "grp:alt_shift_toggle" EndSection If you have Nvidia card, don't forget to edit /etc/X11/xorg.conf.d/20-nvidia.conf and change Driver from "kbd" to "evdev" in InputDevice section: Section "InputDevice" Identifier "Keyboard0" Driver "evdev" EndSection Y...

Using querySelector in Selenium WebDriver

Sometimes it's very helpful if we are able to click some element directly, by calling JavaScript click event. For example, this can be the case when the element is not visible, or not clickable, thus we cannot use native WebDriver methods. WebDriver driver = new FirefoxDriver(); JavascriptExecutor js = (JavascriptExecutor)driver; js.executeScript("document.querySelector('.pane .object_options .dropdown-toggle span').click();");
