Python Unit Testing and Automation with pytest

Writing reliable software requires more than just code that runs—it requires ensuring your code continues to work as your project grows. Automated unit testing enables developers to detect bugs early and refactor with confidence. This comprehensive guide equips you with foundational testing skills in Python, beginning with core testing terminology and progressing through essential testing patterns using the pytest framework. In this course, you will learn to: Understand fundamental testing concepts, assertions, and test organization in Python; Write clean unit tests using pytest functions and test discovery features; Manage test setups and teardown routines using reusable pytest fixtures; Parameterize test cases to evaluate multiple input scenarios efficiently; Isolate external dependencies using test doubles and mock objects; Measure code coverage to identify untested branches in your application. You will begin by exploring basic testing vocabulary and framework setup before working through fixture design, test organization, and isolation techniques using written explanations and practical code snippets. Designed for beginners with a basic knowledge of Python syntax, this course requires no prior experience with software testing. Start reading today to write maintainable, reliable Python code with confidence.
