What is Unit testing?

 

Unit testing is a process where individual parts of a software (like functions or methods) are tested to ensure they work correctly. Each part is tested on its own, separate from the rest of the application.

Key Points

• Isolated Tests: Focus on one small piece of the code at a time.
• Automated: Tests are usually run automatically.
• Early Detection: Bugs are found early in development.
• Documentation: Tests show how the code should work.

Benefits

• Better Code Quality: Ensures each part works correctly.
• Easier Maintenance: Makes updating and fixing the code simpler.
• Faster Development: Catches issues early, speeding up the process.
• Confidence: Developers can make changes knowing the tests will catch any new issues.
