Testing is crucial in React projects to ensure that components behave as expected. It helps developers catch bugs early, improves the reliability of applications, and builds confidence when making changes or refactoring code. By having a strong test suite, teams can ship features faster and maintain a better developer experience.

Key reasons why testing is important:

• Catch bugs early: Identifies errors before they reach production.
• Ensure component behavior: Confirms that UI components render and function correctly with different props and user interactions.
• Facilitates refactoring: Developers can update or refactor code with confidence if tests protect against regressions.
• Improves documentation: Tests often serve as live documentation of how components should behave.
• Boosts collaboration: Teams can work together smoothly knowing that tests will highlight any unexpected changes.

In short, testing is not just a safety net — it’s an essential part of building high-quality, maintainable React applications.
