What is Unit Testing?

Unit Testing is a development process in which smallest unit of an application code is tested to ensure expected working. Kent Beck developed Extreme Programming (XP), a software development methodology and unit testing evolved as a part of that methodology. In programming context, an unit could be a class, method, function or other smallest segment of code that can be tested and verified in isolation.
