Charitha Kankanamge

Quality is a key to success of service-oriented projects. Utilization of proper tools is important to the outcome of web service testing methodology. Being the leading open source web services testing tool, soapUI helps to build robust and flexible automated tests in a productive manner.Web Services Testing with soapUI guides you on adopting best web service testing mechanisms with the industry leading open source testing tool, soapUI. You will learn to use soapUI effectively in testing service-oriented solutions focusing on testing functional as well as non-functional characteristics of web services. SoapUI is capable of testing JDBC data sources, web applications, RESTful services and web services exposed over transports such as JMS. The book discusses all these features and much more, in detail, through practical and clear examples.This book is focused on learning soapUI in order to test web services in an effective manner. It starts with a general introduction to service-oriented architecture (SOA) followed by testing aspects of service-oriented solutions. This book aims to give readers a comprehensive overview of usage of soapUI in SOA and web services testing projects. Starting with an overview of SOA and web services testing, you will quickly get your hands dirty with a sample project which makes use of open source web service engine, Apache Axis2. All demonstrations and hands-on exercises are based on this sample project. The tests in a soapUI project are organized into TestSuites, TestCases and TestSteps.

Learn LLVM 12. A beginner's guide to learning LLVM compiler tools and core libraries with C++

Kai Nacke

LLVM was built to bridge the gap between compiler textbooks and actual compiler development. It provides a modular codebase and advanced tools which help developers to build compilers easily. This book provides a practical introduction to LLVM, gradually helping you navigate through complex scenarios with ease when it comes to building and working with compilers.You’ll start by configuring, building, and installing LLVM libraries, tools, and external projects. Next, the book will introduce you to LLVM design and how it works in practice during each LLVM compiler stage: frontend, optimizer, and backend. Using a subset of a real programming language as an example, you will then learn how to develop a frontend and generate LLVM IR, hand it over to the optimization pipeline, and generate machine code from it. Later chapters will show you how to extend LLVM with a new pass and how instruction selection in LLVM works. You’ll also focus on Just-in-Time compilation issues and the current state of JIT-compilation support that LLVM provides, before finally going on to understand how to develop a new backend for LLVM.By the end of this LLVM book, you will have gained real-world experience in working with the LLVM compiler development framework with the help of hands-on examples and source code snippets.

ARM!AE Cortex!AE M4 Cookbook. Over 50 hands-on recipes that will help you develop amazing real-time applications using GPIO, RS232, ADC, DAC, timers, audio codecs, graphics LCD, and a touch screen

Mark Fisher, Dr. Mark Fisher

Embedded microcontrollers are at the core of many everyday electronic devices. Electronic automotive systems rely on these devices for engine management, anti-lock brakes, in car entertainment, automatic transmission, active suspension, satellite navigation, etc. The so-called internet of things drives the market for such technology, so much so that embedded cores now represent 90% of all processor’s sold. The ARM Cortex-M4 is one of the most powerful microcontrollers on the market and includes a floating point unit (FPU) which enables it to address applications. The ARM Cortex-M4 Microcontroller Cookbook provides a practical introduction to programming an embedded microcontroller architecture. This book attempts to address this through a series of recipes that develop embedded applications targeting the ARM-Cortex M4 device family. The recipes in this book have all been tested using the Keil MCBSTM32F400 board. This board includes a small graphic LCD touchscreen (320x240 pixels) that can be used to create a variety of 2D gaming applications. These motivate a younger audience and are used throughout the book to illustrate particular hardware peripherals and software concepts.C language is used predominantly throughout but one chapter is devoted to recipes involving assembly language. Programs are mostly written using ARM’s free microcontroller development kit (MDK) but for those looking for open source development environments the book also shows how to configure the ARM-GNU toolchain. Some of the recipes described in the book are the basis for laboratories and assignments undertaken by undergraduates.
