Automated testing is more efficient than manual testing, and more and more industries in the IT sector are opting for automated tests for applications, whether desktop or web.

Selenium is the most popular tool used to automate browsers, and as it is currently on the path to become a W3C standard, its importance in the testing world will only grow. Selenium is open source, platform independent, and can be used to interact in a programmatic way with web applications through any major vendor browser (such as Google Chrome, Mozilla Firefox, Internet Explorer, Safari, Microsoft Edge, and Opera).

This book is designed for software quality assurance and development personnel who want to learn how to automate browser activity and web-based user interface tests with Selenium.

, WebElement Functionality , talks about how to use browser developer tools to review the code behind a web page and how to find and interact with elements to later write and perform tests on them.

, Advanced Element Function, covers how to navigate, search, and identify different elements in a web application by using effective element locators.

, Waiting For Elements , trains the students on how to write a stable automation script by waiting for an element to be present. It discusses the differences between implicit and explicit waits, and finally shows how to effectively synchronize a script in a custom condition.

, Page Object Model , covers the principles behind Page Object Model, and how to model and implement an automation script.

, Writing Tests , talks about test frameworks and how to choose them; as well as how to create test scripts and how to validate results.

, Analysis and Troubleshooting , discusses the root cause of a test failure by analyzing a test report, and tracking down errors It also covers how to separate real issues from flaky tests.
