Topics Covered
- 1. Introduction to Python TDD: Learners will be introduced to Test-Driven Development (TDD) principles in Python, understanding the benefits and setting up their development environment. They will gain foundational skills in writing simple tests and running test suites.
- 2. Basic Unit Testing in Python: This module covers writing unit tests for Python functions and classes, using popular testing frameworks like PyTest. Learners will practice creating test cases, assertions, and test fixtures.
- 3. Refactoring for Testability: Learners will learn techniques to refactor legacy code to improve testability, including identifying and isolating dependencies, and writing modular code.
- 4. Advanced Testing Strategies: This module delves into more advanced testing strategies, such as integration testing, end-to-end testing, and testing asynchronous code. Practical skills in setting up and using these strategies will be developed.
- 5. Mocking and Stubs in Testing: Learners will study the use of mocking and stubbing to simulate external dependencies during testing. They will practice using libraries like unittest.mock and pytest-mock.
- 6. Refactoring with Refactoring Patterns: This module focuses on applying refactoring patterns to improve the structure and maintainability of legacy code while preserving functionality. Practical exercises in applying these patterns will be included.
- 7. Continuous Integration and Deployment: Learners will learn how to integrate TDD practices into a continuous integration and deployment (CI/CD) pipeline. They will practice setting up and configuring CI/CD tools to automate testing and deployment processes.
- 8. Performance Testing and Optimization: This module covers performance testing techniques and how to optimize code for better performance. Practical skills in using tools like pytest-benchmark will be developed.
- 9. Testing Complex Systems: Learners will explore testing complex systems, including database interactions, external APIs, and complex workflows. They will practice writing tests for these scenarios and handling complex test setups.
- 10. Applying TDD in Real-World Projects: In this final module, learners will apply all the skills and knowledge gained in a capstone project. They will refactor a real-world legacy codebase using TDD principles and demonstrate their ability to handle complex refactoring tasks with confidence.
