Foundations of Test and Behavior Driven Development (TDD/BDD)

Writing code without tests often leads to endless debugging and fragile applications. By adopting test-driven and behavior-driven development, you shift from reacting to bugs to preventing them entirely. This text-only course guides you through the practical philosophy of writing tests first. You will understand how to structure your development process around clear requirements, turning specifications into executable documentation that keeps your codebase robust as it grows. What you'll learn: - Understand the core principles of TDD using the Red-Green-Refactor cycle. - Apply BDD concepts to translate user stories into clear, automated test specifications. - Write structured test suites using modern testing frameworks and mock objects. - Implement Gherkin syntax (Given-When-Then) to align business goals with technical tests. - Integrate automated testing workflows into modern continuous integration environments. You will start with key terminology, basic concepts, and foundational definitions of software testing before moving through practical TDD cycles and BDD scenarios. The material concludes with strategies for integrating these practices into your daily software development workflow. This course is designed for beginner developers, QA professionals, and product managers who want to understand modern testing methodologies. No prior testing experience is required.
