Computer software is widly used such as nuclear electric development, missle system, large scale industrial process etc. In these systems, small mistake may bring on serious damage. There are unit testing, integration testing, and system testing by the view of scale. Also there are functional testing and structral testing by the view of methodology. There are some trouble-such as inheritance, encapsulation, and reusable-object-oriented program apply to procedural program testing in unit testing. However object-oriented program testing is need for additional consideration. Object-oriented program is constitute interaction of message. So almost object-oriented program testing is focus to functional testing. But functional testing technique cannot find error because don't know implementation of program. In this paper, I suggest Class Call Graph in order to know how interaction object and function. And then perform traditional testing technique to object-oriented program testing.

Random Testing: The Best Coverage Technique - An Empirical Proof

K Koteswara Rao,Prof GSVP Raju 보안공학연구지원센터 2015 International Journal of Software Engineering and Vol.9 No.12

Soft testing is one way of assuring quality of the software. There are many testing techniques to test the software, however random testing is one among the best alternatives, which will generate the test inputs based on some dissemination. It is evaluated theoretically and concluded that the performance of random testing is very impressive when it is compared with partition testing even though it gives good results for testing. Here in this paper we addressed the difference in coverage between random testing and partition testing, here we have taken one example program and written the test cases for that. To test the program we have used automated tools JUnit for partition testing and Randoop for random testing. Once it is over using EclEmma the coverage of test cases is evaluated and proved RT is best.

Sunju Park,Seong-Cheon Woo,Hyo-Jeong Ban,Siwoo Lee,김송이,진희정 한국한의학연구원 2021 Integrative Medicine Research Vol.10 No.2

Background: Currently, genetic testing is widely used to understand individual characteristics. In Korea, genetic testing has been in use, but not actively in Korean Medicine (KM). To examine the perceptions of genetic testing, we performed online survey to Korean Medicine doctors (KMDs). Methods: The survey was a mobile-based study that was developed by 6 survey specialists based on electronic database search results. The questionnaire consisted of 6 categories: general characteristics of respondents, understanding of genetic testing, demand for using genetic testing, application field and utilization level of genetic testing, limitations of genetic testing, and plans and necessary efforts to begin using genetic testing based on an 11-point Likert scale. Results: With the response rate of 27.2% (n = 544), 46.9% of respondents answered that they understood the definition and mechanism of genetic testing. About 80% of KMDs responded that they would be willing to use genetic testing results; a notable reason for this was the need for more objective and evidence-based test results. KMDs recognized that genetic testing could not only provide personalized treatment and care, but also help communicate with patients. Conclusions: This study observed KMDs’ perceptions of the potential clinical benefits of genetic testing. We confirmed that development of genetic testing technology, knowledge of their use, and new technology-friendly policies are essential for expanding the genetic testing technology in Korean medicine.

Slam testing of a door module is one of the most significant fatigue-related testing process to meet the qualified performance guideline that is stipulated by major car makers. And every testing procedure of the slam testing is done as slamming the moving part of a door module by hydraulic actuators in practice. Current testing situation is required considerable efforts on the way to prepare the slam testing and even more, even a single specimen result sacrifices at least two weeks or more physically. In this paper, a accelerated similarity testing methodology of a door module is proposed using vibration test equipment instead of the honest testing procedure, that is purely slamming the target system repeatedly up to a failure mode. The response of a door plate module during slam testing indicates that fundamental resonance behaviors of the specimen accumulates the fatigue damage on hot spot of the door plate module. So, The accelerated similarity alternatives of the slam testing is proposed by the block cycle excitation of which spectrum is consisted of resonance frequencies of a target system. Also, the calibration of block cycle testing is conducted through the comprehend the fact of failure mode obtained by the multi-axial vibration testing.

A Program Model Based Regression Test Selection Technique For D Programming Language

Nitesh Chouhan,Dr. Maitreyee Dutta,Dr. Mayank Singh 보안공학연구지원센터 2015 International Journal of Hybrid Information Techno Vol.8 No.6

Software testing can be stated as the process of validating and verifying that a computer program, application and product [1]. Software testing can also provide an objective, independent view of the software to allow the business to appreciate and understand the risks of software implementation. Software testing, depending on the testing method employed, can be implemented at any time in the development process. Traditionally most of the test effort occurs after the requirements have been defined and the coding process has been completed. Testing can never completely identify all the defects within software. A primary purpose of testing is to detect software failures so that defects may be discovered and corrected. Testing cannot establish that a product functions properly under all conditions but can only establish that it does not function properly under specific conditions. There are many approaches to software testing. Reviews, walkthroughs, or inspections are referred to as static testing, whereas actually executing programmed code with a given set of test cases is referred to as dynamic testing. Regression testing is an important but expensive software maintenance activity performed with the aim of providing confidence in modified software. Regression test selection techniques reduce the cost of regression testing by selecting test cases for a modified program from a previously existing test suite. Regression testing is done every time when a program is modified to ensure that the modifications do not introduce new bugs into previously validated code. Regressions Testing can be done by collectively perform Regression Test Selection, Test Minimization and Test Case Priotrization Technique. An important research problem, in this context, is the selection of a relevant subset of test cases from the initial test suite. Regression test selection (RTS) techniques minimize both the regression testing time and effort. Regression test selection (RTS) techniques select a subset of valid test cases from an initial test suite (T) to test that the affected but unmodified parts of a program continue to work correctly. Use of an effective regression test selection technique can help to reduce the testing costs in environments in which a program undergoes frequent modifications. D is a new programming language. This is an object-oriented, imperative, multi-paradigm system programming language. Regression testing on D programming language still untouched by researchers. Our research attempts to bridge this gap by introducing a techniques to revalidate D programs. A framework is proposed which automates both the regression test selection and regression testing processes for D programming language. As part of this approach, special consideration is given to the analysis of the source code of D language. In our approach system dependence graph representation will be used for regression test selection for analyzing and comparing the code changes of original and modified program. First we construct a system dependence graph of the original program from the source code. When some modification is executed in a program, the constructed graph is updated to reflect the changes. Our approach in addition to capturing control and data dependencies represents the dependencies arising from object-relations. The test cases that exercise the affected model elements in the program model are selected for regression testing. Empirical studies carried out by us show that our technique selects on an average of 26.36. % more fault-revealing test cases compared to a UML based technique while incurring about 37.34% increase in regression test suite size.

Genetic testing in clinical pediatric practice

유한욱 대한소아청소년과학회 2010 Clinical and Experimental Pediatrics (CEP) Vol.53 No.3

Completion of the human genome project has allowed a deeper understanding of molecular pathophysiology and has provided invaluable genomic information for the diagnosis of genetic disorders. Advent of new technologies has lead to an explosion in genetic testing. However, this overwhelming stream of genetic information often misleads physicians and patients into a misguided faith in the power of genetic testing. Moreover, genetic testing raises a number of ethical, legal, and social issues. Diagnostic genetic tests can be divided into three primary but overlapping categories: cytogenetic studies (including routine karyotyping, high-resolution karyotyping, and fluorescent in situ hybridization studies), biochemical tests, and DNA-based diagnostic tests. DNA-based testing has grown rapidly over the past decade and includes pre- and postnatal testing for the diagnosis of genetic diseases, testing for carriers of genetic diseases, genetic testing for susceptibility to common non-genetic diseases, and screening for common genetic diseases in a particular population. Theoretically, once a gene’s structure, function, and association with a disease are well established, the clinical application of genetic testing should be feasible. However, for routine applications in a clinical setting, such tests must satisfy a number of criteria. These criteria include an acceptable degree of clinical and analytical validity, support of a quality assurance program, possibility of modifying the course of the diagnosed disease with treatment, inclusion of pre-and postnatal genetic counseling, and determination of whether the proposed test satisfies cost-benefit criteria and should replace or complement traditional tests. In the near future, the application of genetic testing to common diseases is expected to expand and will likely be extended to include individual pharmacogenetic assessments.

Reverse Engineering from Exploratory Testing to Specification-based Testing

Dea-Kwang Kim,Lee-Sub Lee 보안공학연구지원센터 2014 International Journal of Software Engineering and Vol.8 No.11

GUI testing takes a crucial role of acceptance testing. SBT (Specification-based Testing) and ET (exploratory testing) are mainly used for GUI testing. SBT is not practical because it requires high level experts and a lot of efforts for creating specifications. Therefore, in most cases, test cases are manually written based on ET by testers. However, ET requires heavy labor cost for enhancing coverages. Thus, it is not programmatic for better coverage than SBT. In this paper, to take advantages of SBT we proposed a method applying a reverse engineering concept which automatically generates formal specifications from manually written test cases. The paper also proposed a method to expand uncovered test paths and test data. The generated specifications could contribute to enhance the quality of software with a few additional manual tasks.

의사국가시험을 컴퓨터시험으로 치를 수 있을까?

허선 대한의사협회 2012 대한의사협회지 Vol.55 No.2

In November 2011, the standing Committee of the Korean Medical Licensing Examination (KMLE) recommended that the National Health Personnel Licensing Examination Board introduce computerized testing to the KMLE. Therefore this article contextualizes and explores the possibility of applying computerized testing to the KMLE. Computerized testing comprises computer-based testing (CBT), ubiquitous-based testing (UBT), internet-based testing (IBT), and computerized adaptive testing (CAT). CBT refers to testing administered via a computer as the user interface, while testing with a smart phone or smart pad as the user interface is known as UBT. IBT is testing done online, and CAT is testing tailored so that each item provided fits the examinee’s ability level. The benefits and drawbacks of each computerized testing option were surveyed. Among them, I propose CAT as the final goal for KMLE. In order to implement the com-puterized testing more effectively, it is recommended that items contain multimedia data and should involve interpretation or problem-solving. More evidence is needed to support the positive impact of computerized testing for undergraduate medical education and primary health care. Since the rapid progress of information technology such as internet bandwidth and human-com-puter interface methods, the introduction of computerized testing to KMLE will soon be plausible. It is possible to increase the quality of the KMLE with the introduction of computerized testing. Medical schools should prepare for the new testing environment of the KMLE by recruiting or training specialists in this field.

제품의 심미적·형태적 반영을 고려한 디자인 사용성 평가 제안 : 플라스틱 사출 자전거 디자인 사용성 평가를 중심으로

김별 ( Kim Byeol ),하은영 ( Ha Eun Young ),유아현 ( Yu A Hyeon ),조운대 ( Cho Un Dae ),조광수 ( Cho Kwang Soo ) 한국산업디자이너협회(한국인더스트리얼디자인학회) 2021 산업디자인학연구 Vol.15 No.1

연구배경 최근 기업들은 제품 디자인에 사용자들의 다양한 니즈를 반영하기 위해 사용성 평가를 사용하는 추세다. 하지만 일반적 사용성 평가의 결과만으로 제품 디자이너가 제품에 사용자의 니즈를 온전히 반영할 수 있다고 보기 어렵다. 이에 사용성 평가와 함께 시각적 요구사항이 반영될 수 있는 평가가 진행될 필요성이 있다. 따라서 본 연구자는 사용성 평가에 제품의 시각적 평가가 포함된 평가방법인 가칭‘Visual Pointing’을 제안하고 그 가능성을 확인하고자 한다. 연구방법 첫째, 제품 디자이너의 관점에서 일반적 사용성 평가의 단점을 보완한 비주얼 포인팅을 제안한다. 둘째, 비주얼 포인팅의 가능성을 확인하기 위하여 제품의 심미적, 형태적 반영을 고려한 사용성 평가 실험을 통해 타당성을 검증한다. 셋째, 비주얼 포인팅을 적용한 실험 결과를 확인하여 보완점을 찾고 개선안을 제안한다. 연구결과 일반적 사용성 평가의 결과만을 가지고 디자이너에게 제품에 심미적, 형태적 개선 방향을 제안하기 어려운 부분이 있음을 확인하였다. 또한 비주얼 포인팅을 적용한 결과, 일반적 사용성 평가와 함께 보완된 시각적 평가가 가능하며 심미적, 형태적 결과 도출을 통해 제품 디자이너에게 더욱 명확하게 결과를 전달할 수 있음이 확인되었다. 결론 본 연구는 일반적 사용성 평가를 보완한 시각적 평가방법인 가칭‘Visual Pointing’을 제안하고 새롭게 재구성된 평가항목을 적용한 실험을 통해 보완된 사용성 평가의 가능성을 제시하는 것에 의의가 있겠다. Background Recently, companies are using Usability Testing to reflect various needs of users in product design. However, it is hard to say that product designers can fully reflect the needs of users in their products only as a result of a general Usability Testing. Thus, it is necessary to conduct an testing that can reflect visual requirements along with Usability Testing. Therefore, the researcher would like to propose the provisional name Visual Pointing, an testing method that includes a visual assessment of the product in the Usability Testing, and confirm its potential. Methods First, we propose Visual Pointing that complements the defect of general Usability Testing from the perspective of product designers. Second, to verify the possibility of Visual Pointing, feasibility is verified through Usability Testing experiments considering aesthetic and morphological reflection of the product. Third, we check the experimental results applied with Visual Pointing to find complementary points and propose an improvement plan. Results With only the results of the general Usability Testing, we confirm that there are some difficulties in suggesting aesthetic and morphological improvement directions for the product to designers. Furthermore, the application of Visual Pointing confirmed that complementary visual evaluations along with general Usability Testing are possible and that aesthetic and morphological results can be more clearly communicated to product designers. Conclusion This study will be meaningful in proposing a provisional ‘Visual Pointing’, a visual evaluation method that complements general Usability Testing, and suggesting the possibility of a complementary Usability Testing through experiments with newly reconstructed evaluation items.
