Description

Step by step directions to get started with Selenium using Python as a programming languageKey features Get introduced to the world of Selenium Understand the concept of locators in Selenium Learn how to write scripts using Selenium WebDriver in Python Learn the concepts of synchronization Learn how to handle different HTML elements like form, table, alert, frame, and dropdown Learn about design patterns like the page object model, data-driven tests, and adding assertionsDescriptionSelenium is the most popular open source test automation tool available in the market. In the last decade, its usage has dramatically increased in the IT sector across all types of organizations. The reason for its popularity is mainly because it supports multiple programming languages, test executions on multiple browsers and operating systems. In this book, we will learn about the different components of Selenium. We will discuss the concepts of WebDriver and learn how to apply test automation concepts with it to automate the testing of our application. We will learn the process of recognizing the test objects on the screen and writing Selenium commands using Python as a programming languageWe will also discuss how to use design patterns like the page object mode and data-driven testing to ensure building a robust test framework, which is modular and scalable in nature. What will you learnThe objective is to introduce the world of Selenium to a manual tester who knows Python as a programming language. You will learn to demystify the concept of identifying test objects and writing Selenium commands to create robust test scripts. This book will help learn to automate different HTML elements, which we come across in the web applications we need to test. You will understand how to build a good test suite by learning the concept of design patterns like the page object model and data-driven tests to ensure maintainability of code. Who this book is for This book is for people who have experience in manual testing and knowledge in Python as a programming language. This book will also be helpful for a developer who knows Python as a programming language and is looking for test automation as a career option. Table of contents1.

Preface
Selenium is a test automation tool for web application functional testing that has gained significant popularity in the last decade or so. The reason for its popularity is that it is open source, it supports scripting in different programming languages like Java, C#, Python, Ruby, Perl, and JavaScript. It automates different browsers on different operating systems. No other tool in the market comes with this rich feature set with zero license cost. Many organizations big or small have moved towards Selenium. Also due to adaptation of Agile practices, CI/CD pipeline automation is no longer an option but a necessity.
Selenium implementation using Java as a programming language is widely used. In recent years, a significant rise is seen in the implementation of Selenium with Python, as this language has gained popularity. In this book, we will learn about the concepts of test automation using the tool Selenium, and implement them using the programming language Python.
Chapter 1 – In this chapter, introduces Selenium, the different components of Selenium, discusses why we should use Selenium and the Selenium architecture.
Chapter 2 – In this chapter, discusses the Selenium IDE, its installation, how to create the first test for record and playback. It covers Selenium commands.
Chapter 3 – In this chapter, talks about the concepts of the locators. Locators of Selenium allow us to identify the objects uniquely on the page so that we can perform actions on it.
Chapter 4 – In this chapter, covers the setting system for writing our very first test using selenium webdriver on the eclipse IDE, using the PyDev plugin. It runsa test on Chrome, Firefox and the Internet Explorer browser.
Chapter 5 – In this chapter, discusses the WebDriver, WebElements, and By classes of the selenium webdriver module of Python. It covers the different methods associated with these classes.
Chapter 6 – In this chapter, discusses the unittest module. It is the unit test framework of the Python programming language. It also discusses its assertion module to help us assert our scripts.
Chapter 7 – In this chapter, discuss the concept of synchronization. It covers static wait and dynamic wait.
Chapter 8 – In this chapter, explains how we can parameterize our test using an external dataset like a csv file.
Chapter 9 – In this chapter, discusses how Selenium automates different HTML elements. Form elements, tables, drop down.
Chapter 10 – In this chapter, looks at some other HTML elements like frame, alerts and action class of Selenium
Chapter 11 – In this chapter, discusses the concept of the page object model, which is a famous design pattern for Selenium test suite creations, which help manage object information.
Chapter 12 – In this chapter, discusses how to implement the Selenium grid by invoking the Selenium server in the hub mode and node mode. It also covers how to make some changes in scripts to point it to the hub for execution.
