Non-functional testing

Testing software for non-functional behavior

Non-functional testing is testing software for its non-functional requirements: the way a system operates, rather than specific behaviors of that system. This is in contrast to functional testing, which tests against functional requirements that describe the functions of a system and its components.

Non-functional testing includes:

  • Accessibility testing
  • Baseline testing
  • Compliance testing
  • Documentation testing
  • Endurance testing or reliability testing
  • Load testing
  • Localization testing and Internationalization testing
  • Performance testing
  • Recovery testing
  • Resilience testing
  • Security testing
  • Scalability testing
  • Stress testing
  • Usability testing
  • Volume testing
