Program Inspection And Testing Techniques For Code Clones And Refactorings In Evolving Software, Zhiyuan Chen Oct 2017

Program Inspection And Testing Techniques For Code Clones And Refactorings In Evolving Software, Zhiyuan Chen

Student Work

Developers often perform copy-and-paste activities. This practice causes the similar code fragment (aka code clones) to be scattered throughout a code base. Refactoring for clone removal is beneficial, preventing clones from having negative effects on software quality, such as hidden bug propagation and unintentional inconsistent changes. However, recent research has provided evidence that factoring out clones does not always reduce the risk of introducing defects, and it is often difficult or impossible to remove clones using standard refactoring techniques. To investigate which or how clones can be refactored, developers typically spend a significant amount of their time managing individual clone …


Improving Software Quality By Synergizing Effective Code Inspection And Regression Testing, Bo Guo May 2017

Improving Software Quality By Synergizing Effective Code Inspection And Regression Testing, Bo Guo

Student Work

Software quality assurance is an essential practice in software development and maintenance. Evolving software systems consistently and safely is challenging. All changes to a system must be comprehensively tested and inspected to gain confidence that the modified system behaves as intended. To detect software defects, developers often conduct quality assurance activities, such as regression testing and code review, after implementing or changing required functionalities. They commonly evaluate a program based on two complementary techniques: dynamic program analysis and static program analysis. Using an automated testing framework, developers typically discover program faults by observing program execution with test cases that encode …
