How to handle on load event listener in katalon, once page load, i want to fire event
In Katalon Studio (or in Selenium world), there is no “on load event listener” concept like JavaScript.
Usually people do “WebUI.verifyElementPresent(TestObject, timeout)” (or waitForPageLoad() etc) to wait for the page to be completely loaded; and once the page has been loaded, continue to do some tests.
If you want to write your test in an event-driven fashion, then you might prefer Playwright. See
