lithium\test\Integration

Extends lithium\test\Unit
class

This is the base class for integration tests.

Integration tests are for determining that different parts of the framework will work together (integrate) as expected. An example of a common integration test would be for ensuring that an adapter interacts correctly with the class it is designed to interface with. Example: the Session class and the Php adapter. Unit tests will ensure that both the Session and Php classes behave correctly under isolation, while an integration test ensures that the two classes interact and interface correctly.
