Understand the TDD cycle - You will learn to work deliberately in the Red–Green–Refactor loop, so you can build code in small steps, catch defects earlier, and keep your project easier to maintain over time.
Write Python tests - You will practice creating unit tests with unittest and pytest, so you can write your own tests with clear assertions, exception checks, and a structure ready for real project work.
Start with a test - You will go through your first TDD iterations from an empty task to a working solution, helping you define expected behavior before implementation and make coding decisions with more confidence.
Test functions and classes - You will learn how to test simple functions as well as class and method behavior, which will help you design code that is more predictable, modular, and easier to extend safely.
Organize test scenarios - You will use setUp, tearDown, and test parameterization to build repeatable scenarios faster, reduce duplication, and keep larger test suites easier to read and maintain.
Isolate external dependencies - You will learn mocking and stubbing for code that depends on APIs, databases, or files, so you can verify application logic without relying on unstable or slow external systems.
Avoid common pitfalls - You will see when to choose unit tests and when integration tests make more sense, how to avoid overengineering, and how to keep tests useful instead of turning them into overhead.
Apply TDD in a project - While building a simple application, you will practice the full TDD workflow in context, making it much easier to transfer this approach into your own everyday development tasks.
Python basics - You should be comfortable with basic Python syntax, including functions, conditionals, loops, and working with data, so you can follow examples and write your own code.
Working with classes - You should understand what classes, objects, and methods are in Python, because during the training you will test object behavior and build simple code structures.
Running Python code - You should be able to run a Python script from the terminal or your development environment, so you can execute tests smoothly and review each iteration as you go.
Project basics - It will help if you already know how to read simple code and move around a project structure, because you will work with test files and code developed step by step.
