After completion of software Integration and Integration testing, the development team is releasing a software build to Test engineer team.

The testing team is conducting system testing on that software in two sub levels such as

  1. Functional Testing
  2. Non-Functional Testing

Functional testing is concentrating on customer requirements and the Non-Functional testing is concentrating on customer expectations.
