Unit testing involves testing individual units of code to ensure they function as intended. Unit tests isolate and test each part of a program to show they are correct. Benefits of unit testing include finding problems early, facilitating change, simplifying integration, and serving as living documentation. PHPUnit is a popular unit testing framework for PHP, which can be installed via PEAR. Tests are written to make assertions and test exceptions, data, and dependencies. Results can be logged in verbose mode or testdox format.

- 2. What is a unit test? In computer programming, unit testing is a method by which individual units of source code are tested to determine if they are fit for use. A unit is the smallest testable part of an application. http://en.wikipedia.org/wiki/Unit_testing
- 3. For whom? Unit tests are typically written and run by software developers to ensure that code meets its design and behaves as intended. http://en.wikipedia.org/wiki/Unit_testing
- 4. What for? The goal of unit testing is to isolate each part of the program and show that the individual parts are correct. A unit test provides a strict, written contract that the piece of code must satisfy. As a result, it affords several benefits. Unit tests find problems early in the development cycle. http://en.wikipedia.org/wiki/Unit_testing
