Puppeteer

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.

# Tips for writing effective XPath

The practices below can help us write an effective XPath. They have already been discussed in the course so far:

* Always use relative XPath; it starts with (`//`).

* Look for unique `id` or `name` attributes, or combinations using XPath operators (`or`, `and`, etc ).

* Use function or a combination of functions (`contains`, `text()`, etc.) and attributes for writing the XPath expression. 

* Look for `sibling`, `ancestors`, `descendants` or `parents` to identify the web element uniquely.

* ***Avoid*** using `text` comparison to locate as much as possible, since any change in the text will break the XPath.

* ***Avoid*** using any dynamic attribute to locate the XPath. Rather, use the techniques discussed in the earlier lessons to identify the element uniquely.

* ***Avoid*** using absolute XPath (`/`), *always* use relative XPath (`//`).
