Encapsulation, a fundamental concept in object-oriented programming (OOP), not only promotes code organization and security but also greatly improves the testability of your codebase.
In this article, we’ll explore how encapsulation facilitates unit testing in Python, providing you with practical insights and code examples.
Understanding Encapsulation
Encapsulation involves bundling data and methods that operate on that data within a single unit, typically a class. This principle helps hide the internal state of an object and exposes only the necessary functionality through well-defined interfaces.
The Importance of Unit Testing
Unit testing is a critical aspect of software development that involves testing individual units or components of a system in isolation. By ensuring that each unit functions correctly on its own, unit testing helps detect bugs early in the development process and provides confidence in the code’s correctness.
