Practical Python Testing with Pytest and Static Analysis

Writing functional code is only half the battle; ensuring it stays functional as it grows requires systematic testing. Untested code is brittle code that is difficult to maintain and refactor. This course provides a foundational understanding of modern testing methodologies in Python, enabling you to build applications that are easier to debug, refactor, and deploy with confidence. What you'll learn: * Understand the core principles of unit testing, integration testing, and test-driven development (TDD). * Master the pytest framework, including parameterized tests and fixtures for efficient test setup and teardown. * Apply mocking and patching techniques using built-in Python tools to isolate external dependencies and services. * Configure static analysis tools and code formatters to enforce consistent style and catch common errors before runtime. * Practice writing comprehensive test suites for functions, classes, and basic application logic. We begin with key testing terminology and move quickly into hands-on examples using the powerful pytest library. The material then covers advanced topics like dependency isolation and integrating quality checks into your development workflow. This course is designed for beginner Python developers who want to establish a strong foundation in code reliability. No prior experience with testing frameworks is required.
