Python Unit Testing: Fundamentals and Pytest

Python developers need confidence that their code works reliably and can be changed without breaking existing functionality. Unit testing is the critical skill required to achieve this confidence. Master the essential practices of unit testing and refactoring to build robust, high-quality Python applications from the start. What you'll learn: * Understand the core concepts of unit testing, integration testing, and test isolation principles. * Write clear, effective test cases using standard Python assertion patterns and the popular pytest framework. * Apply essential refactoring techniques to improve existing code structure and testability. * Configure and utilize pytest fixtures and parameterized testing for efficient test setup and data handling. * Practice using mocking and patching techniques to manage external dependencies and isolate units under test. The course begins with foundational testing theory, moves into practical implementation using pytest, and concludes with strategies for refactoring code to be more testable and maintainable. Learners will follow written explanations and code examples to solidify their understanding. This course is designed for beginner Python developers who want to adopt professional testing practices immediately. No prior testing experience is required.
