Python Unit Testing with Unittest and Pytest

Writing reliable code requires a structured approach to testing. Understanding how to automate tests ensures your Python software remains stable, bug-free, and easy to maintain as it grows. This course guides you step-by-step through the core concepts of software testing in Python. You will move from foundational testing terminology to writing robust unit test suites with both the built-in unittest module and the popular pytest framework. What you'll learn: - Understand foundational testing concepts, terminology, and test-driven principles - Write isolated unit tests using the standard unittest library - Create flexible and readable test suites with pytest - Utilize pytest fixtures to manage test setup and teardown efficiently - Implement parametrized tests to verify multiple execution scenarios - Apply basic mocking techniques to isolate code dependencies - Measure code coverage to identify untested paths in your codebase. The course begins with key terminology, basic assertion methods, and core testing paradigms before moving to practical test design and execution patterns. Designed for beginner Python developers who want to introduce automated testing into their workflow, with no prior testing experience required.
