Topic: Unit Testing - Simplifies integration

															Unit testing helps to eliminate uncertainty in the units themselves and can be used
															in a bottom-up testing style approach. By testing the parts of a program first and then 
															testing the sum of its parts, integration testing becomes much easier.
															A heavily debated matter exists in assessing the need to perform manual
															integration testing.


															While an elaborate hierarchy of unit tests may seem to
															have achieved integration testing, this presents a false sense of confidence
															since integration testing evaluates many other objectives that can only be
															proven through the human factor. Some argue that given a sufficient variety of
															test automation systems, integration testing by a human test group is unnecessary. Realistically, the
															actual need will ultimately depend upon the characteristics of the product
															being developed and its intended uses. Additionally, the human or manual
															testing will greatly depend on the availability of resources in the
															organization.
