Fault Detection Time: An Important Parameter of Test Case Sequencing for Regression Testing

Abstract

Regression testing is one of the imperative activities of software maintenance. It requires lot of efforts to choose those test cases from test suite which are most promising and the execution of which traces maximum number of faults present in software. Due to limited time budget available for regression testing some test case selection techniques are always needed to meet this requirement. Various test case selection techniques have been proposed by different researchers. A Fault-Detection Time selection technique has been proposed in this paper that selects a test case which detects that fault which has been allotted minimum time in the test suite. Through a comparative study, it has been observed that proposed technique performs equally well as other two parallel test case prioritization techniques; Average Percentage of Fault Detection (APFD) based prioritization, and Optimal Test Case Prioritization (OTCP) with minimum number of random selections of test cases.
