Writing reliable tests is essential for delivering stable web applications, yet simulating how a real person interacts with your software can feel challenging. This text-based course guides you through the core concepts of integration testing, showing you how to write clear, maintainable test suites that mirror actual user behavior. You will learn to navigate pages, fill out forms, and verify content just like a real visitor would. By completing this course, you will transform your approach to testing, moving from basic unit tests to comprehensive integration flows that catch bugs before they reach production. You will gain the confidence to refactor your Rails applications knowing your critical user journeys are fully protected. What you'll learn: - Understand the fundamentals of integration testing and how Capybara integrates with Rails - Simulate user actions using essential interaction methods like filling inputs, choosing options, and clicking buttons - Query and verify page content using robust assertions and selectors - Handle modern dynamic web behaviors, including basic asynchronous page changes and state transitions - Structure clean, readable, and maintainable test suites using modern Rails testing conventions You will start with foundational testing concepts and key terminology before moving step-by-step through practical testing scenarios, building up to complete user flow simulations.
