This text-based course guides you through setting up a clean, reliable, and modern testing infrastructure from scratch. You will understand how the testing lifecycle works in Rails and learn to configure your application for maximum development speed and reliability. By reading through clear explanations and structured code examples, you will transition from manual testing to a confident, automated workflow. You will learn to establish a solid foundation where your tests run quickly, isolate database states properly, and guide your daily coding decisions. What you'll learn: - Understand the core principles of Test-Driven Development and the Rails testing lifecycle - Configure test databases and manage migrations specifically for testing environments - Set up modern testing frameworks and essential assertion libraries within Rails - Prepare models, factories, and fixtures to generate clean test data - Apply modern testing practices including database cleaning strategies and environment isolation - Write foundational unit tests for models and validations using TDD workflows This course begins with essential testing terminology and fundamental Rails configurations.
