📼Types of System Testing

With system testing, a QA team gauges if an application meets all of its technical, business and functional requirements. To accomplish this, the QA team might utilize various types of software testing techniques that determine the overall test coverage for an application and help catch critical defects that hamper an application's core functionalities before release.

  • Performance Testing: Performance Testing is a type of software testing that is carried out to test the speed, scalability, stability and reliability of the software product or application.

  • Load Testing: Load Testing is a type of software Testing which is carried out to determine the behavior of a system or software product under extreme load.

  • Stress Testing: Stress Testing is a type of software testing performed to check the robustness of the system under the varying loads.

  • Scalability Testing: Scalability Testing is a type of software testing which is carried out to check the performance of a software application or system in terms of its capability to scale up or scale down the number of user request load.

  • Integration testing - Tests the interfacing and interaction of system components that have been already tested as standalone units. Focuses on the interfaces between system units.

  • Functional testing - Tests that the system meets its required functional and non-functional requirements. Involves test cases designed based on system specifications.

  • Security testing - Attempts to compromise the system's security to find vulnerabilities by simulating attacks. Checks for threats like privilege escalation, SQL injection, cross-site scripting, etc.

  • Recovery testing - Determines how quickly the system can recover from any failure and return to normal operations. Involves introducing failures and observing system behavior during and after recovery.

  • Usability testing - Checks how easily users can understand and use the system effectively. Often involves actual users performing representative tasks on the system.

  • Regression testing - Repeats previously performed tests to ensure no new defects have been introduced and existing problems were properly fixed. Provides confidence in system stability.
