Hi,,,

System testing of software or hardware testing is performed on an integrated system to verify and assess the system with its requirements. System testing falls within the scope of black box testing, and as such, should require no knowledge of the interior design of the code or logic.

In general, the test system has, as its entry, all the "integrated" software components that have successfully passed the integration tests and the software itself incorporated into any applicable hardware system (s). Test system is a limiting type of testing, it seeks to detect defects both within the inter-assemblages "and also in the system as a whole.

System testing is performed throughout the system as part of a functional specification (s) (FRS) and / or a System Requirement Specification (SRS). Test system is a phase of inquiry, where the emphasis is to have almost a destructive attitude and test not only the design but also the behavior and believed the same expectations. It is also intended to test and beyond the limits defined in the hardware / software specification (s). Test system includes load testing and stress testing. Once the load testing and stress tests are completed successfully, the next level of Alpha or Beta Testing Testing will proceed.

Types of system testing

The following examples are the different types of tests that should be considered during the system test:

  • GUI software testing
  • Usability testing
  • Benchmarks
  • Compatibility tests
  • Error handling test
  • Load test
  • Volume test
  • Stress tests
  • Help for usability testing
  • Testing for safety
  • Scalability tests
  • Capacity test
  • Sanity testing
  • Smoke tests
  • Test
  • Ad hoc tests
  • Regression testing
  • Reliability testing
  • Recovery test
  • Test facility
  • Maintenance Test
  • Accessibility tests
