What we have learnt
- Unit testing ensures code behaves as expected and helps catch bugs early.
- Mocking allows isolation from external dependencies to create reliable tests.
- Debugging tools help identify issues in code, while logging provides insight into runtime behavior.
Key Concepts
- -- Unit Testing
- A practice of testing individual components of code in isolation to ensure their correctness.
- -- unittest Module
- Python's built-in framework for organizing tests, handling assertions, and managing test cases.
- -- pytest
- A powerful testing framework that simplifies writing tests with advanced features such as fixtures and parameterized tests.
- -- Mocking
- Replacing external dependencies with controllable stand-ins for reliable tests.
- -- Debugging
- The process of finding and resolving defects or problems in code.
- -- Logging
- The practice of recording information about a program’s execution to track issues and understand behavior.
