What is Unit Testing
Unit tests are basically written and executed by software developers. The goal of unit testing is to segregate each part of the program and test that the individual parts are working correctly.
Method: Unit testing comes in the white box testing category. White box testing method is used for unit testing.
When Should Unit Testing be done?
Unit testing is the first level of Testing, it should be performed before the integration testing.
Actor : Generally unit testing performed by the developers. In some special cases, special testers may perform Unit testing.
Benefits of Unit Testing :
Bug detected at the early stage of the development.
It makes the code more reusable. For Unit Testing code should be modular, so it means code easier to use.
Since the bugs are found early in unit testing hence it also helps in reducing the cost of bug fixes.
Debugging is easy. When a test fails, only the latest changes need to be debugged.
