Why you must write unit tests?

[sahithya]

Unit tests are vital in web development to ensure the functionality and quality of code.

They evaluate individual units or components of a web application, helping developers gain confidence, detect bugs, and maintain high standards of quality.

Unit tests catch bugs early, breaking down complex functionalities into testable units.

This proactive approach saves time and effort, preventing issues from propagating and avoiding regressions.

Unit tests act as code documentation, providing clear examples of expected behavior.

They help developers understand and work with the codebase, reducing the risk of unintended consequences.

Unit tests support code refactoring, ensuring desired functionality remains intact.

They encourage collaboration, providing a clear specification of expected behavior for effective communication within the team.

Unit tests make it easier to spot issues when making changes, maintaining a clean codebase.

They prevent the accumulation of technical debt, leading to more maintainable code in the long run.

Unit tests play a crucial role in CI/CD workflows, enabling automated testing.

They catch issues early and ensure new code integrates smoothly, saving time and reducing the risk of errors in production.
