Abstract
Software Defect Prediction (SDP) is one of the most assisting activities of the Testing Phase of SDLC. It identifies the modules
that are defect prone and require extensive testing. This way, the testing resources can be used efficiently without violating the
constraints. Though SDP is very helpful in testing, it’s not always easy to predict the defective modules. There are various issues
that hinder the smooth performance as well as use of the Defect Prediction models. In this report, we have distinguished some of
the major issues of SDP and studied what has been done so far to address them.
