Functional Testing Software Overview

What is Functional Testing Software?

Functional testing is part of product development where the software is tested to make sure that it conforms to the requirements. Functional testing can be manual or automated.Functional testing software typically feeds some input so that the output can be evaluated to see how the software performs.

Besides input/output testing, functional testing is also concerned with testing usability to make sure that the navigation system performs as designed.

Types of Functional Testing

  • Unit testing refers to testing a small unit of code or a single unit of work or single task within the software code. Unit tests are often automated.
  • Smoke testing is preliminary testing to uncover any severe failures that might make more detailed testing impossible. This is sometimes called sanity testing.
  • Interface testing is the process of testing the product’s graphical user interface to make sure that it meets specifications and that navigation works as designed.
  • System testing is testing of a complete, integrated system to make sure that it behaves in compliance with requirements.
  • Regression testing is designed to uncover new bugs after patches or configuration changes have been made to the system.

Functional testing is distinguished from non-functional testing, which is testing of how well the software behaves in terms of performance, scalability etc. rather than the functional requirements of a system or sub-system.
