XPath, or XML path, is a query language used for locating a node from a DOM. It is one of the most common ways of identifying an element while writing Selenium UI tests.

In this course, you will learn various techniques for writing an expression that identifies a complex locator. In the process, you will also learn the tips and tricks of writing an efficient and optimized locator. We have used puppeteer with Javascript to demonstrate evaluating an XPath expression in this course.

This course is designed for both beginner and intermediate level developers, as well as QA engineers who want to master the art of writing effective XPath expressions.
