A Study on the Relation between Software Quality & Test Quantity

Abstract: Testing is an essential phase of software development process. It helps to ensure the quality of the software by finding bugs, errors, and defects that may occur during the development or the deployment of the system. IT companies and field workers, spend a lot of efforts on testing a software. However, how far should testers go with testing? In this research, we study 80 open source real world projects, and explore how much testing code has been written in those projects, in comparison with production code. We also try to find if there is any relation between different project factors, such as: project size, number of contributors and the amount of testing that has been done in those projects. We also give some recommendations to help field workers determine the amount of testing needed for a software.
