Software testing is probably the most critical part in any software development project. Through a series of software functional testing and performance appraisal, developers would be able to determine their product’s reliability before they deploy it in actual IT infrastructures. In essence, functional testing and performance testing are the two most basic pre-deployment stage of any application development initiative. These two test processes will determine if the software would be able to compete with other similar applications.
Of the two test processes, software functional testing plays a significant role in the development. It is process where developers determine if the intended purpose of the application will work as expected. Essentially, functional testing is a way to see if the application’s specification can be executed by users. It involves testing different commands and executable scripts, data handling, and process integration. Functional testing also determines how the program reacts to its host system’s various configurations. There are also issues that can be resolved through functional testing such as program security concerns and stability of its utilities whenever an upgrade has been implemented.
Normally, software functional testing is carried out at the end of development. At first, developers will test their program’s compatibility and performance. Different application components will be written and tested separately if they will interface with the general executable format of the entire application. After all these have been carried out, developers will test run their project and see how its different functions will work. That is why this stage is called software functional testing.
