Test Studio is Telerik's QA solution for automating your manual testing. With Test Studio's standalone edition or Visual Studio plugin, you can rule out the possibility of unreliable test execution and UI recognition, non indicative test results and reports, dispersed test repository, low code coverage, and unaffordable learning curves. With no code, this tool provides an intuitive IDE to effortlessly create maintainable tests. If you are looking for a solution to automate testing for your web, desktop, or mobile application, you can now benefit from Test Studio's rich automation features.Learning Software Testing with Test Studio will illustrate how to reliably automate test cases when it is time to relinquish manual testing habits. This book is all about less theory and more hands-on examples to present a complete manual and automated solution for your ASP .NET, WPF, Silverlight or iOS apps.This book gets you started directly with automation in Test Studio by exploiting its recording powers through series of concrete test cases built around the equipped applications. Each chapter starts with a typical automation problem which is then approached using Test Studio specialized automation features.You will learn how to create record and playback functional, performance, and load tests. Furthermore, we will see how to insert verification steps, logical constructs, convenient logging operations, and how to convert test scripts in order to implement keyword and data-driven architectures. To endow your tests with additional flexibility, each recorded automation feature will be approached from its coded perspective through the usage of the underlying ArtOfTest Test Studio automation library.This book also illustrates how Test Studio can automate pre-conditions, test result inputting, and the capturing of system states during manual test case execution in order to keep the tester's attention focused on the important details.
Learning Spark SQL. Architect streaming analytics and machine learning solutions
Aurobindo Sarkar
In the past year, Apache Spark has been increasingly adopted for the development of distributed applications. Spark SQL APIs provide an optimized interface that helps developers build such applications quickly and easily. However, designing web-scale production applications using Spark SQL APIs can be a complex task. Hence, understanding the design and implementation best practices before you start your project will help you avoid these problems.This book gives an insight into the engineering practices used to design and build real-world, Spark-based applications. The book's hands-on examples will give you the required confidence to work on any future projects you encounter in Spark SQL.It starts by familiarizing you with data exploration and data munging tasks using Spark SQL and Scala. Extensive code examples will help you understand the methods used to implement typical use-cases for various types of applications. You will get a walkthrough of the key concepts and terms that are common to streaming, machine learning, and graph applications. You will also learn key performance-tuning details including Cost Based Optimization (Spark 2.2) in Spark SQL applications. Finally, you will move on to learning how such systems are architected and deployed for a successful delivery of your project.
Learning Splunk Web Framework. Create, extend and publish real time Splunk applications
Vincent Sesto
Building rich applications on the Web using Splunk is now simpler than ever before with the Splunk Web Framework. It empowers developers to build their own web applications with custom dashboards, tables, charts, form searches, and other functionalities in the datasets at their disposal. The book will start with the fundamentals of the Splunk Web Framework, teaching you the secrets of building interesting and user-friendly applications. In the first application, you will learn to analyze and monitor traffic hitting the NASA website and learn to create dashboards for it. You will then learn additional, and more detailed, techniques to enhance the functionalities of the app such as dashboards and forms, editing simple XML, using simple XML extensions, tokens, post-process searches, dynamic drill-downs, the Splunk Web Framework and REST API, and much more. The second app will use historical stock market data and will create custom dashboards using Splunk Web Framework; the book will now cover important topics such as creating HTML dashboards, enhancing the visual appeal of the app using CSS, and moving your app with SplunkJS.The book will provide different and interesting examples instead of the usual “Log, Index, Search, and Graph” so that Splunk will be the first tool readers think of to resolve a problem.
