Abstract

Objectives: Development of an efficient test suite minimization approach in order to reduce the size of a previously acquired test suite and produce a new representative suite which will guarantee the same requirement coverage that was achieved before minimization for an effective and efficient regression testing. Method: Test suite minimizations techniques try to reduce the size and redundancy of test suite by removing certain test cases since requirement covered by them are already covered by other test cases. But, it has been found that the acquired test cases after minimization severely lacks ability to achieve the desirable code coverage because the minimization was done based on a single test adequacy criteria. In this paper, we propose an efficient heuristic based test suite minimization algorithm which will reduce the size of the test suites with respective to multiple test adequacy criterions in order to preserve the fault detection effectiveness and code coverage characteristics of the final test suite. Findings: Our experimental results indicate that a significant percentage of reduction in the test suite size is achieved when the minimization is performed with respect to multiple test adequacy criterions. Our approach is unique compared to the existing approaches in the sense that, we carried out minimization based on multiple test adequacy criterions while most of the existing approaches usually take one or two criterions into consideration. The proposed approach is evaluated based on two well known software testing metrics; one indicate the percentage of reduction in test suite size and the second one indicate the percentage of code coverage achieved by the minimized test suite. Our experimental results indicate that a significant percentage of reduction in the size as well as significant code coverage characteristics is achieved when the minimization is done according to the proposed approach. Improvements: The important contribution of this study is that, it presents a novel and efficient test suite minimization technique that optimizes the test suite size based on multiple adequacy criterions.

Abstract

This study is focused on the preliminary investigations of soil of southern district Bannu, KPK, Pakistan in the form of geotechnical and mineralogical details, obtained by performing various kinds of tests on soil samples collected from selected spots, where the unusual cracks were observed to have been appeared in the pavements, boundary walls and some other parts of the buildings. Similar cracks were observed in most parts of the world where the soil was found to be expansive which depends on clay mineralogy, binding agents, migration of water beneath the surface and the ability of soil to absorb water. X-Ray diffraction analysis was used to study the minerals present in the soil and its fabric was studied with the help of Scanning Electron Microscopy and those minerals were explored which are not involved in the swelling phenomenon such as kaolinites, chlorites, quartz and poligorskite. Geotechnical investigation was performed by digging the trial pits and collecting soil samples in polythene bags for determining its Atterberg, s limits and studying different geotechnical reports prepared by soil mechanics lab, UET Peshawar. The soil was found to lie within the range termed as low plasticity clay whose swelling potential is moderate to medium.
