People seem to face a lot of problems in
differentiating functional and non- functional
testing. To eliminate misunderstandings and to
proof check your knowledge, lets have a brief
learning about the two.

Functional Software Testing
First of all, functional testing is always done
against an applications business requirements
which mean it is a black box type of
testing. It takes the entire integration system
to quantify the compliance of the system with
its requirements. The functional testing type is
carried out on the basis of the product
functional specification document.

While performing the functional tests, one should
bear in mind the following procedural steps

• Prepare the test data based on each functions
  specifications
• The inputs for the tests would be the business
  requirements itself
• The outputs must be found from the functional
  specifications
• Execute the test cases
• And finally, observe both the outputs- the actual
  and the expected ones

5
There are a plethora of tools available for
performing and automating web functionality
testing services. However, the types of tests to
be considered as functional are

• Unit Testing
• Smoke Testing
• Sanity Testing
• Integration Testing
• White box testing
• Black Box testing
• User Acceptance testing
• Regression Testing
•  

6
The Non-Functional type of testing is performed
based on the non-functional requirements of the
product.

• Non-functional requirements are those that
  imitate the quality of a product and
  specifically in terms of its users suitability
  perspective.
