Benefits of Unit Testing

• Increases confidence in changing/maintaining code
• Codes are more reusable as Unit testing requires code to be modular.
• Development is faster and bugs are found early on in the development cycle.
• Cost of fixing a bug at the time of writing a unit test is much less as compared to fixing it if the code is in production
• Debugging is easy as when a test fails, only the latest changes need to be debugged.
• Code is more reliable.
