How Static Analysis Works?
Static analysis is performed early in the life cycle, early feedback on quality issues has been established. For example, early validation of the user’s requirements. Since analysis is performed earlier, by detecting defects at an early stage, the cost for rework is often relatively low and thus a relatively cheap improvement of the quality of software products can be achieved. As rework efforts are reduced, there is an increase in the development of productivity figures. The advantage of evaluation by the team is that there is an exchange of information or data between all the participants of the team. The static analysis contributes to an increased awareness of quality issues. One of the reasons for using static analysis is related to the characteristics of the programming language themselves.
What are the defects in code analysis?
Defects that arise during the analysis of code depend on the tool. Some of them are as follows: unreachable code that can safely be removed.
