Abstract: Abstract-Test suite augmentation techniques are used in regression testing to identify code elements affected by changes and to generate test cases to cover those elements. In previous work, we studied two approaches to augmentation, one using a concolic test case generation algorithm and one using a genetic test case generation algorithm. We found that these two approaches behaved quite differently in terms More recently, we empirically studied several factors that can affect augmentation techniques [34]. The… Show more

“…For example, in previous work [9] where the goal was to improve upon manually written tests, we re-used the existing test cases by modifying the search operators of EVOSUITE such that whenever a new test case was generated, it was based on an existing test case with a certain probability. Xu et al considered the reuse of test cases during test suite augmentation for DSE [37] or search-based and hybrid techniques [36], by using the old tests as starting population of the next test generation run; in this approach the success of the augmentation depends strongly on the previous tests.…”

“…To address this problem, recently, researchers started working on test suite augmentation techniques which create new test cases for areas that have been affected by changes [17], [18], [19], [20], [21], [22]. Apiwattanapong et al [17] and Santelices and Harrold [18] presented a propagation-based approach which uses program dependence analysis and symbolic execution to identify areas affected by code changes, and then provides test requirements for changed software.…”

Xu et al [19], [20] presented an approach to generate test cases by utilizing the existing test cases and adapting concolic and genetic test case generation techniques. Taneja et al [21] proposed an efficient test generation technique that uses dynamic symbolic execution, eXpress, by pruning irrelevant paths.…”
