Selenium WebDriver 3 Practical Guide. End-to-end automation testing for web and mobile browsers with Selenium WebDriver - Second Edition

UNMESH GUNDECHA, Satya Avasarala

Selenium WebDriver is an open source automation tool implemented through a browser-specific driver, which sends commands to a browser and retrieves results. The latest version of Selenium 3 brings with it a lot of new features that change the way you use and setup Selenium WebDriver. This book covers all those features along with the source code, including a demo website that allows you to work with an HMTL5 application and other examples throughout the book.Selenium WebDriver 3 Practical Guide will walk you through the various APIs of Selenium WebDriver, which are used in automation tests, followed by a discussion of the various WebDriver implementations available. You will learn to strategize and handle rich web UI using advanced WebDriver API along with real-time challenges faced in WebDriver and solutions to handle them. You will discover different types and domains of testing such as cross-browser testing, load testing, and mobile testing with Selenium. Finally, you will also be introduced to data-driven testing using TestNG to create your own automation framework.By the end of this book, you will be able to select any web application and automate it the way you want.

Selenium WebDriver Quick Start Guide. Write clear, readable, and reliable tests with Selenium WebDriver 3

Pinakin Chaubal

Selenium WebDriver is a platform-independent API for automating the testing of both browser and mobile applications. It is also a core technology in many other browser automation tools, APIs, and frameworks. This book will guide you through the WebDriver APIs that are used in automation tests.Chapter by chapter, we will construct the building blocks of a page object model framework as you learn about the required Java and Selenium methods and terminology.The book starts with an introduction to the same-origin policy, cross-site scripting dangers, and the Document Object Model (DOM). Moving ahead, we'll learn about XPath, which allows us to select items on a page, and how to design a customized XPath. After that, we will be creating singleton patterns and drivers. Then you will learn about synchronization and handling pop-up windows. You will see how to create a factory for browsers and understand command design patterns applicable to this area.At the end of the book, we tie all this together by creating a framework and implementing multi-browser testing with Selenium Grid.

Podstawowym zastosowaniem Selenium jest implementacja testów systemowych w celu weryfikacji funkcjonowania aplikacji. Narzędzie to zdobyło ogromną popularność - stanowi ono jedno z wiodących rozwiązań w zakresie testów systemowych. Jest chętnie używane zarówno przez duże organizacje, jak i samodzielnych programistów. Ten praktyczny przewodnik po Selenium WebDriver w wersji 4 z uwzględnieniem implementacji w Javie jest przeznaczony dla programistów Javy, inżynierów jakości i testerów. Przedstawiono w nim główne aspekty zautomatyzowanej nawigacji po stronie, manipulacji w przeglądarce, interakcji z elementami, naśladowania działań użytkownika i automatycznego zarządzania sterownikami. Opisano koncepcję wzorca projektowego POM, który pozwala na modelowanie stron internetowych w zorientowanych obiektowo klasach. Zaprezentowano różne sposoby przeprowadzania testów i wprowadzania odpowiedniej ich kolejności, omówiono też zasady analizy błędnych wykonań w celu określenia przyczyn niepowodzenia. Pokazano także możliwości wzbogacania testów o inne technologie, służące na przykład do raportowania wyników, generowania danych czy implementacji szczególnych przypadków użycia. W książce między innymi: przygotowanie środowiska do testów end-to-end z Selenium WebDriver automatyczne interakcje z aplikacjami internetowymi strategie testowania na wielu przeglądarkach testowanie działania formularzy, komunikatów w oknach i skryptów JavaScript posługiwanie się złożoną infrastrukturą w testach Selenium WebDriver wykorzystanie programowania zorientowanego obiektowo w testowanych aplikacjach Selenium: testowanie, które daje niezawodność i bezpieczeństwo!

Server Side development with Node.js and Koa.js Quick Start Guide. Build robust and scalable web applications with modern JavaScript techniques

Olayinka Omole

Every developer wants to build modular and scalable web applications. Modern versions of JavaScript have made this possible in Node.js, and Koa is a Node.js framework that makes it easy. This book is the ideal introduction for JavaScript developers who want to create scalable server side applications using Node.js and Koa.js.The book shows you how Koa can be used to start projects from scratch, register custom and existing middleware, read requests, and send responses to users. We will explore the core concepts in Koa, such as error handling, logging, and request and response handling. We will dive into new concepts in JavaScript development, and see how paradigms such as async/await help with modern Node.js application development.By the end of this book, you will be building robust web applications in Koa using modern development paradigms and techniques of Node.js development.

Serverless Analytics with Amazon Athena. Query structured, unstructured, or semi-structured data in seconds without setting up any infrastructure

Anthony Virtuoso, Mert Turkay Hocanin, Aaron Wishnick,...

Amazon Athena is an interactive query service that makes it easy to analyze data in Amazon S3 using SQL, without needing to manage any infrastructure.This book begins with an overview of the serverless analytics experience offered by Athena and teaches you how to build and tune an S3 Data Lake using Athena, including how to structure your tables using open-source file formats like Parquet. You’ll learn how to build, secure, and connect to a data lake with Athena and Lake Formation. Next, you’ll cover key tasks such as ad hoc data analysis, working with ETL pipelines, monitoring and alerting KPI breaches using CloudWatch Metrics, running customizable connectors with AWS Lambda, and more. Moving on, you’ll work through easy integrations, troubleshooting and tuning common Athena issues, and the most common reasons for query failure. You will also review tips to help diagnose and correct failing queries in your pursuit of operational excellence. Finally, you’ll explore advanced concepts such as Athena Query Federation and Athena ML to generate powerful insights without needing to touch a single server.By the end of this book, you’ll be able to build and use a data lake with Amazon Athena to add data-driven features to your app and perform the kind of ad hoc data analysis that often precedes many of today’s ML modeling exercises.

Serverless computing in Azure with .NET. Build, test, and automate deployment

Sasha Rosenbaum

Serverless architecture allows you to build and run applications and services without having to manage the infrastructure. Many companies have started adopting serverless architecture for their applications to save cost and improve scalability. This book will be your companion in designing Serverless architecture for your applications using the .NET runtime, with Microsoft Azure as the cloud service provider. You will begin by understanding the concepts of Serverless architecture, its advantages and disadvantages. You will then set up the Azure environment and build a basic application using a sample text sentiment evaluation function. From here, you will be shown how to run services in a Serverless environment. We will cover the integration with other Azure and 3rd party services such as Azure Service Bus, as well as configuring dependencies on NuGet libraries, among other topics. After this, you will learn about debugging and testing your Azure functions, and then automating deployment from source control. Securing your application and monitoring its health will follow from there, and then in the final part of the book, you will learn how to Design for High Availability, Disaster Recovery and Scale, as well as how to take advantage of the cloud pay-as-you-go model to design cost-effective services. We will finish off with explaining how azure functions scale up against AWS Lambda, Azure Web Jobs, and Azure Batch compare to other types of compute-on-demand services.Whether you’ve been working with Azure for a while, or you’re just getting started, by the end of the book you will have all the information you need to set up and deploy applications to the Azure Serverless Computing environment.
