System Testing: Complicated Process in Simple Words

System testing is one of the stages of the whole software system testing lifecycle (STLC), which comprises three others: unit testing, integration testing, and acceptance testing. Each of these stages has their objectives and technical features. This article dedicated to one of the most volumetric phases.So system testing is a software testing which executing on an accomplished integrated system with a purpose to find out if the structure, functional, data and other issues comply with initial stakeholders’ requirements. The main goal of executing this fraction is to checkup functional, as well as non-functional requirements in the system on the whole. Herewith testers detecting such defects as the wrong usage of system resources, unexpected combinations at the user level, incompatibility with an environment, unintended scenarios, absence of functionality or its’ incorrect performance and ect.Let’s have a simple example for a better understanding of how does this testing phase is executing. Imagine you are an electric guitar manufacturer. Electric guitar consists of many details such as fretboard, tunes, body, volume/tone controls, electronic fillings etc. Let’s say you completed chips and boards installation into the guitar body. Each of them has exact functions and resemble, in our case, separate units. But altogether, this units shape an integration system. In order to make sure they work properly you run a test-drive. So, actually, this verification procedure of integration system calls system testing. It shall be carried out on a systematic basis during the construction process to avoid unexpected surprise on the final chord. There is a big chance that off-color element in the very beginning stage of the whole product development lifecycle can roll back entire project.Within system testing stage the following types of tests should be executed:
