Unit testing involves verifying the smallest testable parts of an application—usually individual functions or methods—in isolation. These tests confirm that each unit of code behaves correctly based on expected inputs and outputs.
Purpose
- Catch bugs early in development
- Facilitate code refactoring with confidence
- Improve overall code quality and maintainability
Characteristics
- Fast to execute
- Easy to automate
- Written and maintained by developers
Best Practices
- Test one function or logic unit at a time
- Use clear, descriptive test names
- Keep tests independent and repeatable
- Include both typical and edge-case scenarios
