Rails View Testing with Capybara and End-to-End TDD

Are your Rails views breaking silently when you update your backend code? Testing the user interface is often the most neglected part of web development, yet it is critical for delivering a seamless user experience. This text-based course guides you through the principles of Test-Driven Development (TDD) specifically tailored for Rails views, helping you catch UI bugs before they reach production. You will transform from manually clicking through your application to writing automated, reliable tests that verify your HTML, CSS classes, and interactive elements. What you'll learn: - Understand the core concepts of TDD and how they apply specifically to the Rails view layer - Configure RSpec and Capybara in a modern Rails environment for seamless integration testing - Write precise assertions to test DOM elements, CSS selectors, and dynamic page content - Implement system tests to simulate real user interactions like clicking buttons and filling out forms - Apply modern testing best practices including clean setup, AAA pattern, and robust selectors - Debug failing view tests efficiently by inspecting the rendered HTML output This course starts with foundational testing concepts, guiding you through the essential terminology of assertion libraries, drivers, and the test lifecycle. You will then progress step-by-step through practical written scenarios, learning how to write tests first, watch them fail, and implement the exact code needed to make them pass. This course is designed for beginner to intermediate Rails developers who want to adopt a professional testing workflow; no prior testing experience is required, though a basic familiarity with Rails and Ruby is recommended.
