It is also aimed at test engineers who need to automate the testing of complex systems. Knowledge of Ruby is helpful, but even someone new to the language should find it easy to follow the code and tests.\u003c\/p\u003e\u003cb\u003eWhat You Will Learn\u003c\/b\u003e\u003cul\u003e\n\u003cli\u003eIdentify a unit of software for the purposes of testing\u003c\/li\u003e\n\u003cli\u003eManage test states with hooks, fixtures, and mocks\u003c\/li\u003e\n\u003cli\u003eHandle external web services in tests using various techniques\u003c\/li\u003e\n\u003cli\u003eConfigure RSpec flexibly and cleanly using support code and environment variables\u003c\/li\u003e\n\u003cli\u003eInteract with rich web apps in tests using Capybara\u003c\/li\u003e\n\u003cli\u003eBuild the right feature with behaviordriven development\u003c\/li\u003e\n\u003cli\u003eCustomize matchers and failure messages\u003c\/li\u003e\n\u003cli\u003eVerify correct development and production environments\u003c\/li\u003e\n\u003c\/ul\u003e\u003cb\u003eIn Detail\u003c\/b\u003e\u003cp\u003eThis book will teach you how to use RSpec to write highvalue tests for realworld code. We start with the key concepts of the unit and testability, followed by handson exploration of key features. From the beginning, we learn how to integrate tests into the overall development process to help create highquality code, avoiding the dangers of testing for its own sake.\u003c\/p\u003e\u003cp\u003eWe 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 behaviordriven development (BDD) and testdriven development (TDD).\u003c\/p\u003e\u003cp\u003eThe 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 wellinformed decisions on their own.\u003c\/p\u003e\u003cb\u003eStyle and approach\u003c\/b\u003e\u003cp\u003eThis comprehensive tutorial is packed with realworld examples of testing with RSpec. The most important features of RSpec are introduced in the early chapters and are used in examples of growing complexity in the following chapters. Concepts and methodologies are discussed in detail.\u003c\/p\u003e","brand":"Packt Publishing, Limited","offers":[{"title":"Default Title","offer_id":47039173460208,"sku":"9781784395902","price":39.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0737\/7593\/9824\/files\/9781784395902_p0.jpg?v=1763726522","url":"https:\/\/shop-qa.barnesandnoble.com\/products\/9781784395902","provider":"Barnes \u0026 Noble (DEV)","version":"1.0","type":"link"}
