#lmti #learnmoretrainings
In this video, we address a common Selenium error — the Invalid Selector Exception. Learn why this exception occurs, its root causes, and how to effectively handle it in your test automation scripts. This tutorial is explained in Tamil to help Tamil-speaking QA professionals understand Selenium debugging more comfortably.
InvalidSelectorException in Selenium occurs when the provided selector (like CSS or XPath) is invalid
.This means Selenium can't parse the selector correctly.
1. Syntax Errors in XPath or CSS
2. Using CSS Selectors with Unsupported Expressions - # , .
3. Invalid XPath Axes
4. Compound Class - space
