Synopsis

Test-driven development (TDD) is a programming workflow that helps you build your apps by specifying behavior as automated tests. The TDD workflow future-proofs apps so that they can be modified without fear of breaking existing functionality. Another benefit of TDD is that it helps software development teams communicate their intentions more clearly, by way of test specifications.
This book teaches you how to apply TDD when building React apps. You’ll create a sample app using the same React libraries and tools that professional React developers use, such as Jest, React Router, Redux, Relay (GraphQL), Cucumber, and Puppeteer. The TDD workflow is supported by various testing techniques and patterns, which are useful even if you’re not following the TDD process. This book covers these techniques by walking you through the creation of a component test framework. You’ll learn automated testing theory which will help you work with any of the test libraries that are in standard usage today, such as React Testing Library. This second edition has been revised with a stronger focus on concise code examples and has been fully updated for React 18.
By the end of this TDD book, you’ll be able to use React, Redux, and GraphQL to develop robust web apps.

    Birds, hormones, and extraordinary behavior: The story of the tiny but mighty golden-collared manakin of Panama 
     
     
      
    This book is the story of a remarkable bird, the golden-collared manakin (Manacus vitellinus) of Panama. Males of this species perform one of the most elaborate, physically complex, and noisy courtship displays of any animal on the planet. Barney A. Schlinger delves into the specialized neurons, muscles, bones, and hormonal systems underlying the manakin's unique courtship behavior, creating a rich life-history account that integrates field observations and evolutionary biology with behavioral ecology, anatomy, physiology, biomechanics, and general ornithology. 
     
     
      
    The personal lives of investigators and the natural history of the Panamanian rainforest provide context for this account of the bird's fascinating behavior. Schlinger clearly and approachably explains basic concepts in disciplines such as avian anatomy, endocrinology, sexual differentiation, and the neurobiology of song and aeroacoustics, offering listeners a window into the biology of this exuberant bird. 
     
     
     
    This enhanced audiobook edition includes two short clips of the bird sounds described in the book.

    For the average Joe, fishing may be considered a pretty tedious affair… 
    Long hours spent on the bank by some muddy pond in the middle of nowhere, hunched over a rod, waiting for a bite. 
    Early starts, foul weather, wriggling worms and writhing maggots are enough to turn most people off straight away. But for the staunch angler, this sweeping assumption couldn’t be further from the truth… 
    From wild conspiracies and wacky theories to absurd angling drama, the sport of fishing is more bizarre than most could ever imagine. From the ridiculous ghost story of a man-eating catfish to glorious angling embellishments, The Secret Lives Of Anglers reveals the hidden truths of this puzzling pastime.

    Florida's Space Coast tells the compelling story of America's half century in space exploration from the successful launch of the first two-stage rocket in 1950 through the space shuttle missions of 2000. Told from the unique viewpoint of the people who built the Spaceport, this book shows how the space program transformed the east central Florida coast from a traditional citrus production and tourist area to one of the most influential high-tech centers in the nation. 
     
     
     
    Cape Canaveral was chosen as a missile launch site because of its many geographical advantages. However, in the early years of the space program, the area was far from an ideal place for NASA employees to raise their families. NASA brought in thousands of space-related workers, who, besides sending machines and people into space, had to meet the challenge of moving their families from urban environs to a rural southern county. This book engagingly recounts the parallel stories of the establishment of America's space program and its impact on the development of Brevard County.

    This audiobook is a study guide to prepare for the Respirator Fit Test CNC method exam. It presents more than hundred questions and answers relating to human respiratory system and defence mechanisms, health effects of airborne contaminants, respiratory hazards in the workplace, general respiratory fit testing and respiratory selection requirements, and a sample script to prepare for the submission of a video demonstrating respiratory fit testing by the CNC (Condensation Nuclei Counter) method. 
    Respirator fit testing is a process used to determine whether a particular respiratory protective equipment (RPE) fits an individual properly and provides an adequate seal to protect against hazardous substances. Fit testing is required for tight-fitting respirators, from disposable filtering facepieces to reusable full-face respirators, including some respirators that typically operate in positive pressure mode. 
    There are several methods that can be used for respirator fit testing, including the CNC (Condensation Nuclei Counter) method. The CNC method involves measuring the particulate concentration inside the respirator while the user is wearing it and performing a series of exercises or movements to simulate the physical demands of the job. If the ratio between the air concentration inside the respirator and outside of the respirator meets the respiratory protection standard it is considered to have a good fit. 
    To prepare for the RESP-FIT CNC method exam, this book provides the listener the principles and procedures of respirator fit testing, including the CNC method. This includes excerpts from Australian and International Standards and guidelines and learning about the various types of RPE and their specific fit testing requirements. The listener should also become familiar with the equipment and procedures used in fit testing, as well as the potential risks and limitations of the CNC method.
