    RSpec Essentials

    Mani Tadayon, "RSpec Essentials"
    English | ISBN: 1784395900 | 2016 | PDF/EPUB/MOBI | 199 pages | 5 MB/7 MB/9 MB

    Key Features
    Explore the concept of testability and how to implement tests that deliver the most value
    Maximize the quality of your Ruby code through a wide variety of tests
    Master the real-world tradeoffs of testing through detailed examples supported by in-depth discussion
    Book Description
    This book will teach you how to use RSpec to write high-value tests for real-world code. We start with the key concepts of the unit and testability, followed by hands-on exploration of key features. From the beginning, we learn how to integrate tests into the overall development process to help create high-quality code, avoiding the dangers of testing for its own sake.

    We build up sample applications and their corresponding tests step by step, from simple beginnings to more sophisticated versions that include databases and external web services. We devote three chapters to web applications with rich JavaScript user interfaces, building one from the ground up using behavior-driven development (BDD) and test-driven development (TDD).

    The code examples are detailed enough to be realistic while simple enough to be easily understood. Testing concepts, development methodologies, and engineering tradeoffs are discussed in detail as they arise. This approach is designed to foster the reader's ability to make well-informed decisions on their own.

    What you will learn
    Identify a unit of software for the purposes of testing
    Manage test states with hooks, fixtures, and mocks
    Handle external web services in tests using various techniques
    Configure RSpec flexibly and cleanly using support code and environment variables
    Interact with rich web apps in tests using Capybara
    Build the right feature with behavior-driven development
    Customize matchers and failure messages
    Verify correct development and production environments
