Do Code Clones Matter?

Code cloning inflates maintenance costs and can lead to inconsistent changes to code. This paper presents the results of a large-scale case study that was undertaken to find out if inconsistent changes to cloned code can represent faults.

Did We Test Our Changes?

Testing and development are increasingly performed by different organizations. Poor alignment between the two threatens to increase costs. In this paper, we propose a conceptually simple approach to uncover methods that were changed but never executed during testing.

How much does unused code matter for maintenance?

Software systems contain unnecessary code, which causes unnecessary costs. We present tool-support that employs dynamic analysis of deployed software to detect unused code as an approximation of unnecessary code, and static analysis to reveal its changes during maintenance.
