ATTOL is a software unit testing tool produced by the ATTOL Testware SA in France. It automates the entire software unit testing process: test plan template and test program generation, test program execution, test result analysis and test report generation. ATTOL is suited for the development of embedded software as it allows programmers to operate in native and cross development environments. Particularly, it is used for the development of the flight software which is embedded in the Communication Ocean Meteorological Satellite (COMS). As the flight software is mission-critical, it requires the strict software quality and high testing constraints. The flight software of COMS is verified by ATTOL in native and cross platforms. In 2002, ATTOL was taken over by the IDM Rational Software and has been supplied with the name of Test RealTime (TestRT). The test process of TestRT becomes different from that of ATTOL as TestRT provides the new functionalities that were absent from ATTOL. TestRT provides the new features in the test script language, as well. In this paper, we compare the test process of ATTOL to TestRT With an example of COMS and explain what has been changed in the test script language.

Crowd-based outsourcing is an emerging trend in testing, which integrates advantages of crowd-based outsourcing in software testing. Open call format is used to accomplish various network tasks involving different types of testing levels and techniques at various places by software testers. Crowd-sourced software testing can lead to an improper testing process as if it does not allocate the right task to the right crowd with required skills and not choose the right crowd; it can lead to huge results, which become time-consuming and challenging crowd-source manager for the identification of improper one. The primary purpose of this research is to make crowd-based outsourced software testing more effective and reliable by relating association between the software tester, personality characteristic, and different levels of software testing, i.e., unit, integration, and system, in order to find appropriate personality characteristic for required testing level. This research has shown an observed experiment to determine which software testing level suits which personality characteristic tester in a crowd-based software testing environment. A total of 1000 software testers from different software houses and firms in Pakistan were registered to perform tasks at different software testing levels. The Myers-Briggs Type Indicator (MBTI) test is used to identify each tester's personality characteristic involved in this research study.

내장형 시스템의요구사항이 복잡해짐에 따라 내장형 소프트웨어의 신뢰도를분석하기 위한 도구가 요구되고있다. 소프트웨어의 신뢰도를 분석하는 방법으로는 확률적 모델링을 이용하는데, 다수의 디바이스를 제어하는 내장형 소프트웨어에 적용하기 위해서는 내장형 소프트웨어에 특성화 시킬 필요가 있다. 또한, 기존의 신뢰도 분석 도구는 각 상태간의 전이 확률을 다른 방법으로 측정해야 하고, 한 번 작성한 모델에 대해 재사용을 고려하고 있지 않는다. 본 논문은 내장형 소프트웨어의 신뢰도를 분석하기 위해 내장형 소프트웨어 마르코프 체인 모델과 단위 테스팅 도구를 이용한 신뢰도 분석 도구를 제안한다. 내장형 소프트웨어 마르코프 체인 모델은 신뢰도 분석 방법으로 많이 사용되고 있는 마르코프 체인 모델을 내장형 소프트웨어에 특성화 시킨 모델이다. 그리고 단위 테스팅 도구는 내장형 소프트웨어의 개발환경에 적합한 호스트/타겟 구조를 가지고 있다. 제안하는 도구는 신뢰도 분석을 위해 단위간 전이 확률을 단위 테스트 결과로부터 자동으로 측정하여 기존의 도구보다 용이하게 신뢰도를 분석할 수 있다. 그리고 소프트웨어 모델을 XML 기반의 문서로 표현하여 단위 테스팅 도구가 업데이트 시킨 테스트 결과를 바로 적용할수 있고, 웹 기반의 인터페이스와 SVN 저장소를 이용하여 다수의 개발자가 쉽게 접근할 수 있는 장점을 갖는다. 본 논문에서는 예제를 이용하여 신뢰도의 분석을 보이고 신뢰도 측정에 유용함을 보인다.

Unit testing which is the first task to perform software testing has a major impact on reducing s/w development cost and improving s/w quality. In order to make unit testing become the formal procedure rather than ad-hoc tasks performed by developer, the language-neutral measures are necessary in the programming which is able to specify the test cases. This paper presents a test assertion language for the language-neutral specification of the test cases. The suggested language is based on the ISO/IEC 24709-1, but it supports object oriented features and can describe test cases for unit testing. The test cases that are specified by the language can be used for generating test oracle source codes by test oracle generation tools.

Software testing during development and operation should exercise to obtain the desired software quality and leave failure data set. So far, many software reliability models are classified and can be used to measure a software reliability only based on its failure history But, in practice, developers or testers of software systems must decide which existing software reliability model can be fitted. In this paper, we will show that an appropriate reliability model can be selected by considering relations between characteristics of each testing environment and models' assumptions. Several methods of software testing are presented and discussed. Also, unit test, integrated test, function test and system test that are sequentially exercised during development will be introduced.

최근 사물인터넷 서비스가 점차 보편화되면서 사물인터넷에 사용되는 임베디드 시스템의 신뢰성 및 안전성 이슈가 부각되고 있다. 사물인터넷 시스템 등과 같은 임베디드 시스템 개발의 경우, 개발과정에서 소프트웨어 가상 수행환경을 구축하는 것이 쉽지 않아 단위테스트를 거의 수행하지 않고 있어 기능 신뢰성을 보장하기 어려운 실정이다. 이 연구에서는 실제 플랜트 환경에서 로그 기반 단위테스트 수행방법을 제안한다. 실제 시나리오 수행과정에서 함수별 수행경로를 고려하여 중복된 수행로그를 제거하여 저장되는 로그를 최소화하고 나중에 대표 수행경로만을 분석하여 단위테스트를 진행하는 방식이다. 제안된 방식은 시스템 테스트를 진행하는 과정에서 로그 기반 단위테스트를 효율적으로 수행할 수 있는 장점이 있다.

One of the activities to improve software quality in ISO 26262 is to apply the design principles for software unit design and implementation mentioned in ISO 26262-6, including the evaluation activity. Before evaluation activity, the tool is compared and selected for evaluation. Because the results of the tool a company selected might have an effect on product quality. In this paper, we suggest the method to compare industrial static analysis tools with some of "MISRA C : 2004 Exemplar Suite" and all lessons learned from comparing tools are described. The result on comparison shows that we just couldn't rely on a result of Static Analysis Tool and need to have another appropriate processes and guidelines to evaluate a software.

최근 세계 자동차 업계는 AUTOSAR 소프트웨어 플랫폼 표준을 제정하여 소프트웨어의 신뢰성과 재사용성을 향상키고 있다. 그러나 테스트 시스템 및 테스트 프로세스의 신뢰성 확보와 테스트에 소요되는 기간 단축을 위하여 테스트의 표준화 및 자동화가 절실하다. 특히 RTE 및 베이직 소프트웨어 모듈은 표준화를 만족하는 설계 도구를 사용함으로써 최소한의 신뢰성이 보장되지만, 여전히 응용 소프트웨어 컴포넌트에 대해서는 철저한 테스트가 필요하다. 본 논문에서는 표준화된 AUTOSAR 설계 정보를 이용하여 소프트웨어 컴포넌트의 유닛 테스트를 위한 테스트 시스템의 생성 및 테스트 케이스 생성 자동화 방법을 제안하였으며, 테스트 시스템은 TTCN-3 테스트 표준을 적용하였다. 본 논문에서 제안한 방법을 적용함으로써 차량 소프트웨어의 개발 기간 단축 및 신뢰성을 향상시킬 수 있었다.

It is highly requested that the more complicated embedded software is used for high performance and multiple functions of the systems. This is inevitably increasing the errors. Therefore the embedded software testing is getting important recently. There are not general testing methods which are able to be applied for any embedded systems, but via this research, we introduce a testing method which is based on TTCN-3, a testing standard, for embedded systems. A testing environment for network-based embedded software is implemented with considering the features of TTCN-3 testing which is based on message exchange. The testing environment has two additional parts with TTCN-3 test system, the network analyzer to access the network-based systems and the communication interface which is suggested for embedded systems in previous work, and we have implemented the whole testing environment with interacting these two parts. In addition to the normal testing domain, called single node testing as a unit testing of V-model, we suggest another concept to test multiple nodes in network. It could be achieved by adding keywords such as supervisor and object which are describing the feature of TTCN-3 testing component and generating the TTCN-3 Executable code which contains new keywords. The testing has done for embedded software which is based on CAN network and the demonstration of the testing environment has been shown in this paper.
