How to perform System test?
It is basically a part of software testing and test plan should always contain specific space for this testing.
To test the system as a whole, requirements and expectations should be clear and the tester needs to understand real time usage of application too.
Also, most used third party tools, version of OSes, flavors and architecture of OSes can affect system’s functionality, performance, security, recoverability or installability.
Therefore, while testing system a clear picture about how the application is going to be used and what kind of issues it can face in real time can be helpful. In addition to that, requirements document is as important as understanding the application.
Clear and updated requirements document can save tester from number of misunderstandings, assumptions and questions.
In short, a pointed and crisp requirement document with latest updates along with understanding of real time application usage can make ST more fruitful.
