Unit Testing with Python Training in Dublin, Ireland

Unit testing with Python training focuses on teaching participants how to write effective and maintainable unit tests for Python applications. The course covers the fundamentals of Python's unittest framework, including test case creation, test discovery, and running tests. Participants also learn to use popular libraries like pytest for advanced testing capabilities, such as fixtures, parameterized tests, and mocking. Hands-on exercises include writing test cases, organizing test suites, and integrating testing with CI/CD pipelines for continuous quality assurance. By the end of the training, attendees are equipped to implement robust unit testing strategies to ensure code reliability and quality.

Introduction to Unit Testing and Writing Basic Tests

• Introduction to Unit Testing

• What is unit testing and why is it important in software development?
