Selenium Framework Design in Data-Driven Testing. Build data-driven test frameworks using Selenium WebDriver, AppiumDriver, Java, and TestNG

Carl Cocchiaro

The Selenium WebDriver 3.x Technology is an open source API available to test both Browser and Mobile applications. It is completely platform independent in that tests built for one browser or mobile device, will also work on all other browsers and mobile devices. Selenium supports all major development languages which allow it to be tied directly into the technology used to develop the applications. This guide will provide a step-by-step approach to designing and building a data-driven test framework using Selenium WebDriver, Java, and TestNG.The book starts off by introducing users to the Selenium Page Object Design Patterns and D.R.Y Approaches to Software Development. In doing so, it covers designing and building a Selenium WebDriver framework that supports both Browser and Mobile Devices. It will lead the user through a journey of architecting their own framework with a scalable driver class, Java utility classes, JSON Data Provider, Data-Driven Test Classes, and support for third party tools and plugins.Users will learn how to design and build a Selenium Grid from scratch to allow the framework to scale and support different browsers, mobile devices, versions, and platforms, and how they can leverage third party grids in the Cloud like SauceLabs.Other topics covered include designing abstract base and sub-classes, inheritance, dual-driver support, parallel testing, testing multi-branded applications, best practices for using locators, and data encapsulation.Finally, you will be presented with a sample fully-functional framework to get them up and running with the Selenium WebDriver for browser testing.By the end of the book, you will be able to design your own automation testing framework and perform data-driven testing with Selenium WebDriver.

Selenium WebDriver w Javie. Praktyczne wprowadzenie do tworzenia testów systemowych

Boni García

Selenium pozwala na automatyzację pracy przeglądarek internetowych. Kluczowym komponentem tego projektu open source jest Selenium WebDriver - biblioteka do programistycznego kontrolowania przeglądarek. 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!

Simplifying Application Development with Kotlin Multiplatform Mobile. Write robust native applications for iOS and Android efficiently

Róbert Nagy

Sharing code between platforms can help developers gain a competitive edge, and Kotlin Multiplatform Mobile (KMM) offers a sensible way to do it. KMM helps mobile teams share code between Android and iOS in a flexible way, leaving room for native development.The book begins by helping you to gain a clear understanding of the Kotlin Multiplatform approach, how it works, and how it is different from cross-platform technologies, such as React Native and Flutter, and code sharing options, such as C++. You'll then see how your team can use this software development kit (SDK) to build native applications more effectively by learning timeless concepts and working through practical examples. As you advance, you'll get to grips with the core concepts, understand why UI sharing fails, and get hands-on with developing a small KMM application. Finally, you'll discover expert tips and best practices, along with production- and adoption-related questions, that will help you take the next step in your project and career.By the end of this Kotlin book, you'll have gained a solid understanding of the capabilities of KMM and be able to share code between Android and iOS flexibly.
