Master the art of automated testing using Selenium with Java in this comprehensive guide. Whether you're a beginner or an experienced tester, the book equips you with the knowledge and techniques to build robust and maintainable test suites, ensuring the quality and reliability of your web applications. This book starts introducing the basics of automated testing and the importance of Selenium. It then covers the setup and configuration of the Selenium WebDriver in Java, providing a solid foundation for your testing environment. You'll learn essential aspects of Selenium testing in Java, including working with different browsers, locating web elements using locators, and performing actions on them. From there, you'll explore how to handle dynamic web pages and effective wait mechanisms and verifications to ensure accurate and reliable test results. The book also guides you in setting up Selenium in Java for continuous integration and emphasizes best practices for test codeorganization and maintainability, such as the Page Object Model (POM) and structuring test suites effectively. By the end, you'll have the expertise to address advanced scenarios, such as working with iframes, and know how TestNG enhances Selenium automation, enabling structured tests, data-driven insights, and swift parallel executions. Throughout the book, you'll benefit from real-world examples and practical exercises that reinforce the concepts. The clear explanations and step-by-step guidance make it easy to follow along and apply the knowledge to your own testing projects.

This book will teach you the basics of Streamlit, a Python-based application framework used to build interactive dashboards and machine learning web apps. Streamlit reduces development time for web-based application prototypes of data and machine learning models. As yoüll see, Streamlit helps develop data-enhanced analytics, build dynamic user experiences, and showcases data for data science and machine learning models.Beginner's Guide to Streamlit with Python begins with the basics of Streamlit by demonstrating how to build a basic application and advances to visualization techniques and their features. Next, it covers the various aspects of a typical Streamlit web application, and explains how to manage flow control and status elements. Yoüll also explore performance optimization techniques necessary for data modules in a Streamlit application. Following this, yoüll see how to deploy Streamlit applications on various platforms. The book concludes with a few prototype natural language processing apps with computer vision implemented using Streamlit.After reading this book, you will understand the concepts, functionalities, and performance of Streamlit, and be able to develop dynamic Streamlit web-based data and machine learning applications of your own.What You Will Learn How to start developing web applications using Streamlit What are Streamlit's components Media elements in Streamlit How to visualize data using various interactive and dynamic Python librariesHow to implement models in Streamlit web applicationsWho This Book Is ForProfessionals working in data science and machine learning domains who want to showcase and deploy their work in a web application with no prior knowledge of web development.
