Pytest Fundamentals: Testing Exceptions and Fixtures

Writing reliable Python code requires verifying not just correct functionality, but also how your system handles errors and unexpected input. This course teaches you the foundational skills needed to use Pytest, the industry-standard testing framework, allowing you to build professional and comprehensive test coverage for your projects. What you'll learn: * Understand the core architecture of Pytest, including installation and basic configuration for modern Python projects. * Learn to use fixtures for defining reusable test setups and managing application state efficiently. * Master the use of `pytest.raises` context managers to assert that specific exceptions are raised under defined circumstances. * Apply parameterization techniques to efficiently run the same test logic against diverse input data and expected outcomes. * Practice writing clear, readable test functions and effective assertions to validate application logic. We begin by covering essential testing concepts and setting up your environment, then move step-by-step through writing basic tests, leveraging fixtures, and finally focusing on advanced patterns for exception handling. This course is designed for beginner Python developers who want to adopt professional testing practices. No prior experience with testing frameworks is required.
