We would like to run Web UI tests with Chromium( the binaires are …\Google\Chromium\chrome.exe) but when We use the menu “Run” (with differents browser) it’s all time Chrome(…)\Google\Chrome\Application) which launches.
In Katalon Studio Preferences web browser : we add Chromiun browser or we change the directory path Chrome but nothing…
Can you help
Thank you
