Build Your Own Test Framework
Learn to write better automated tests that will dramatically increase your productivity and have fun while doing so. This book is a build-your-own adventure designed for individual reading and for collaborative workshops. You will build an xUnit automated test framework using JavaScript: initially a clone of Jest, but adding a couple of neat features borrowed from RSpec, the genre-defining tool for behavior-driven development (BDD). Along the way, you will explore the philosophy behind automated testing best practices. The automated test runner is one of the most important innovations within software engineering. But for many programmers, automated testing remains a mystery, and knowing how to write good tests is akin to sorcery. As the chapters of this book unfold, you will see how the humble test runner is an elegant and simple piece of software. Each chapter picks a single feature to build, like the "it" function or the "beforeEach" block. It picks apart the theory of why the ...

Pro Kotlin Web Apps from Scratch
Build production-grade web apps from scratch - without using frameworks - with Kotlin on the Java platform. You'll learn how to use and compose libraries, how to choose between different libraries, and the benefits of explicit and straight-forward code, vs. the implicit magic, conventions, and inversion of control you often see in frameworks. The book teaches the Kotlin language by building production-ready Kotlin code. You'll gain a deep understanding of the idiomatic use of the Kotlin language along with knowledge of how to apply Kotlin in production-grade web apps. The book also bridges the gap between building from scratch and using existing frameworks. For example, you'll learn how to integrate Spring Security-based authentication in web apps written from scratch, so you can leverage existing tooling in your organization without having to take on the entire Spring framework. The first section of the book sets up the base structure of your web app, such as routing, configura ...

Introducing Cisco Unified Computing System
The Cisco Unified Computing System (UCS) can be found in the majority of data centers across the world. However, getting hands-on practice to learn this infrastructure can be difficult, as many companies will push to have it production-ready as soon as possible. Home-labs are also cost-prohibitive, cumbersome, electricity-hungry, and noisy. So, how do you get hands-on experience? With Unified Computing System Platform Emulator (UCSPE) and this book. UCSPE is free and can run on a laptop. Using it along with this book, you will learn how to set up, manage and troubleshoot a UCS, including the fabric interconnects, chassis and IOMs, and servers through the GUI and the CLI. All from the comfort of your own home. Introducing Cisco Unified Computing System will show you how to set up a UCS (comparing the UCSPE to a real-world deployment), customize the hardware, configure the UCS system, and secure it. You'll start by creating an organization and then the policies to control storage ...
