In-Depth Tackling: System Testing

What is system testing? System testing refers to the process of validating a complete and fully integrated software application. We will be learning more about system testing in this article.

Defining System Testing

System testing verifies an application’s performance of tasks as designed. It is a type of black-box testing that concentrates on the functionality of the software. For instance, it might check that every kind of user input produces the intended output across the application.

The QA team gauges if an application meets all of its requirements, which includes technical, business, and functional needs. To accomplish this, the QA team might utilize a variety of test types, including performance, usability, load testing, and functional tests.

System testing should investigate both functional and non-functional requirements. It plays a vital role in producing high-quality software products. It means testing the system as a whole. System testing is responsible for evaluating the end-to-end specifications of the system. It tests an integrated system to confirm if it meets specified requirements.

Types of System Testing

Load Testing

Load testing is necessary for verifying that software performs properly under maximum load on real-life scenarios.

Recovery Testing

Recovery Testing demonstrates a software solution is reliable, trustworthy, and can successfully recoup from possible crashes.

Usability Testing

Usability Testing’s primary focus is on the user’s ease to use the application. Likewise, flexibility in handling controls and the ability of the system to meet its objectives.

Regression Testing

Regression testing involves testing to ensure that none of the changes made throughout the software development process resulted in new defects. It also provides that the old bugs do not reappear.

Functional Testing

Functional testing involves trying to think of any possible missing functions. Testers might make a list of additional functionalities that a product could have to improve it during functional testing.

Hardware/Software Testing

Hardware/Software testing is also called as HW/SW Testing. This is done so the tester gives attention to the interactions. That is, between hardware and also the software.

Migration Testing

Mitigation Testing is done to ensure that the software can be moved from older system infrastructures. And transferred to current system infrastructures. Hence, without any issues.

Importance of System Testing

  • System testing makes the completion of a full testing cycle possible.
  • It happens in a similar environment to that of production. 
  • It helps minimize support calls and also troubleshooting after the product’s deployment. 
  • Both business and application architecture is tested in this testing type.

In Conclusion

System Testing is a type of black-box testing technique. It verifies the system’s compliance against specified requirements. It includes both functional and likewise, non-Functional testing.

A QA team checks if a test case corresponds to each of an application’s most crucial requirements. They also give attention to user stories. These individual test cases resolve the overall test coverage for an app and help the team catch critical defects that hamper an application’s core functionalities before release. A QA team can log and tabulate each error per requirement.

It is the process in which the quality assurance (QA) team evaluates the various components of an application. In other words, the QA team verifies if they interact together in the full, integrated system or application.
