Duplicate defects put extra overheads on software organizations, as the cost and effort of managing duplicate defects are mainly redundant. Due to the use of natural language and various ways to describe a defect, it is usually hard to investigate duplicate defects automatically. This problem is more severe in large software organizations with huge defect repositories and massive number of defect...
Defect prioritization is a decision making process wherein stakeholders determine the temporal order of open defects to be fixed. It is critical to the software development life-cycle as the decisions made during this process directly affect release planning, resource management, and maintenance costs. In fact, defect prioritization is complex as many factors need to be taken into consideration and...
Open source projects incorporate bug triagers to help with the task of bug report assignment to developers. One of the tasks of a triager is to identify whether an incoming bug report is a duplicate of a pre-existing report. In order to detect duplicate bug reports, a triager either relies on his memory and experience or on the search capabilities of the bug repository. Both these approaches can be...
In manual testing, testers typically follow the steps listed in the bug report to verify whether a bug has been fixed or not. Depending on time and availability of resources, a tester may execute some additional test cases to ensure test coverage. In the case of manual testing, the process of finding the most relevant manual test cases to run is largely manual and involves tester expertise. From a...
Although used extensively in industry, regression testing is challenging from both a process management as well as a resource management perspective. In literature, proposed test case prioritization techniques assume a constant pool of test cases with non-changing coverage during the regression testing process, and therefore they work with a fixed, prioritized test suite. However, in practice, test...
