Software system testing is the final stage of software development project. It is a comprehensive testing approach that will determine the full operation of the program if applied on actual IT architectures. When a software system testing is scheduled, it usually means that all other quality tests have been conducted. System testing will try to launch the application on complete computer hardware and determine how the program behaves or reacts to its system host.
After a successful system test, the software is now ready for full deployment and it could be launched and distributed in the market. Software developers usually look for possible compatibility problems during comprehensive system testing. That’s because the software is expected to perform on different environments so it is very important to determine if the software can run on various hardware platforms. Developers also look for possible issues related to the capabilities of the software to communicate with other programs. This is especially true for programs that are expected to execute cross-platform commands and inter-program interface.
Software system testing is usually supervised by a certified software test professional. This is to ensure that the software will conform to the universally accepted standards for applications development. In most cases, the software will be subjected to extreme test procedures in order to determine its stability under extreme usage. System testing also utilizes an investigative approach wherein product developers scrutinize every aspect of the software if it performs according to the expected output. Successful system testing means that the software is safe and will be useful for end users.
