Agile Python Development with TDD and BDD

Writing software that works is good, but writing software that is easy to maintain, adapt, and scale is what separates great developers from the rest. Python developers can achieve this by integrating Test-Driven Development (TDD) and Behavior-Driven Development (BDD) into their daily Agile workflows. This written course guides you through the core principles of test-first development, helping you transform how you design, write, and verify your code. You will transition from writing code and hoping it works to systematically designing software that meets precise business requirements and remains bug-free over time. What you will learn: • Understand the foundational principles of Agile software development and how testing fits into the lifecycle. • Write clean, isolated unit tests using the modern pytest framework. • Implement the Red-Green-Refactor cycle of Test-Driven Development (TDD) to design better software architectures. • Define clear, human-readable software behaviors using Behavior-Driven Development (BDD) methodologies. • Practice writing executable specifications that bridge the gap between technical teams and business stakeholders. • Integrate modern Python practices, including basic type hints and structured testing workflows. The course begins with essential testing terminology and foundational Agile concepts before moving step-by-step through practical TDD and BDD scenarios. You will read through clear code examples, analyze test suites, and learn how to structure Python projects for continuous reliability. This course is designed for beginner to intermediate Python developers who want to improve their code quality and understand Agile testing methodologies, with no prior testing experience required.
