Functional testing

• Functional Testing, also known as
  Specification-based testing, evaluates individual
  functions of a software system to verify that
  they adhere to pre-defined specifications. It
  tests the functional accuracy, interoperability
  of subsystems and compliance with pre-defined
  standards in the context of functional and
  business requirements.

• A proper Functional Testing assures that every
  function of the system is working as required

What is Functional Testing?

• Functional Testing, also known as Specification-ba
  sed testing, evaluates individual functions of a
  software system to verify that they adhere to
  pre-defined specifications. It tests the
  functional accuracy, interoperability of
  subsystems and compliance with pre-defined
  standards in the context of functional and
  business requirements.
• The primary focus of this type of testing is
  validating the results of processing, not how
  the processing is done. It can also be termed as
  a form of Black Box testing.

• Functional Testing is applicable at any level of
  granularity, be it at individual module levels or
  overall system levels. Depending on the level of
  granularity and interdependence, appropriate test
  cases are designed.
• Any software system also has certain functions or
  plugins that can be tested independent of other
  functionalities. Such features are known
  as Independently Testable features. Such features
  either take inputs from modules of software under
  test or provide inputs to them.
