The vehicle handling performances have a close relation with the driver's safety. And the CAT(Computer aided testing) system has been introduced as a powerful tool for improving the handling performances. In this study, a CAT system for effectively measuring and analysing the handling performances is developed based on the windows GUI(Graphic user interface) environment. Especially, in order to derive a lot of significant handling performance parameters from a series of proving ground tests, the CAT system has various functions related to real time measurement, time domain analysis, frequency domain analysis, steady state analysis and so on.

In this paper, we propose and develop a test automation program tool that automates GUI based testing using black box testing technique in Windows environment. The main features of the proposed test automation program tool are as follows. First, an error condition is designated as an image, a screen is captured for each test step, and an error message is detected through comparison of image similarity. Second, the proposed system supports various setting options such as event waiting time during execution and coordinate increment value between each test step. Such black box test automation research was common in environments such as Android and Web, but not in Windows environment. The results of performance evaluation show that the proposed system performs GUI test automation as an image comparison module and confirms that the test is performed normally by confirming process status and error image detection.

Smartphones have features that users feel free to install/delete the program they want. Their emergence makes many developers rush into the Smartphone application development market. Thus, developing good applications quickly is becoming even more intense competition in the market. Because, however, the application development and deployment procedures are simple in the Android environments and anyone can participate in the development easily, applications not validated thoroughly are likely to be deployed. Therefore, a systematic approach that can verify Android-based applications with fewer burdens is required. In this paper, we propose a method that generates automatically GUI-based testing scenarios for the Android applications. The automated test scenario generation can reduce the time which the developer spends on testing, thus it can improve the productivity of the development in the testing phase.

Under the conflicting objectives of maximum user satisfaction and fast launching, there exist great needs for automated mobile app testing. In automated app testing, detection of usage-state changes is one of the most important issues for minimizing human intervention and testing of various usage scenarios. Because conventional approaches utilizing pre-collected training examples can not handle the rapid evolution of apps, we propose a novel method detecting changes in usage-state through graph-entropy. In the proposed method, widgets in a screen shot are recognized through DNNs and 'onverted graphs. We compared the performance of the proposed method with a SIFT (Scale-Invariant Feature Transform) based method on 20 real-world apps. In most cases, our method achieved superior results, but we found some situations where further improvements are required.

The accelerated testing technique using the equivalent load condition plays an important part in development process. However, in the industrial field, the theoretical background and advantages of this accelerated testing technique have been lack of understanding. Because the environmental durability condition forms the foundation of the accelerated testing technique, it is important to analyze the loading components and damage in service environment. In this work, we present the theoretical background and process for accelerated testing, and introduce our accelerated equivalent load analysis program. We developed the GUI program, and the user can easily obtain the result by selecting the program module.

Due to the recent surge of wireless Internet and concurrent development of the end user terminal devices having standardized graphical user interface(GUI) and unified operation mechanism for better interactivity in information representation and ease of use, various efforts on the improvement of GUI is widely recognized as one of the key factors that will usher in the next stages of the wireless Internet for the users. Especially, improved usability along with unique visual effect are considered to be the key elements for GUI considering the rapid improvement of the resolution and color on the end user handset devices; thus, the study and research on the subject of GUI is expected to increase along with the wireless Internet using smart phones. User interface of the wires Internet end user handsets will have a definite and significant effect on the user interaction as well as productivity. Domestically, wireless Internet service providers and GUI design companies are making various efforts in producing a common GUI models for standardized operation scheme and improved graphical display capabilities of the hand phones, PDAs and smart phones. In the study, Nokia 3650 model and Microsoft Orange SPV model were chosen as test devices for usability comparison and data collection to collect directional benchmark data in developing next generation smart phone user interface integrating PDAs and phones. The mail purpose of this study is to achieve the most efficient user accessibility to WAP menu through intensive focus on developing WIPI WAP menu having most effective usability for the users in their twenties and thirties. The result of this study can also be used as the base research materials for WAP service development, VM browser development and PDA browser development. The result of this study along with the evaluation model is expected to provide effective analysis materials on the subject of user interface to the developers of the wireless Internet user devices, GUI designers and service planners while short listing key factors to consider in developing smart phones therefore serving as the GUI guideline of WIPI phones.

Graphic User Interface(GUI) of mobile application is the working environment exchanging informations and almost functions on mobile are operated by it. In order to increase the productivity and to develop reliable mobile software, GUI test is absolutely needed. In this paper, we introduce the scenario based GUI test method and automatic tool(MoGuT). The MoGuT can detect the functional faults using scenarios and operate in SKVM environment.

최근 IT 기기는 GUI를 지원하여 사용자들에게 편의성을 제공하였지만, 개발자들에게는 테스팅에 어려움을 겪게 만들었다. 기존의 GUI 자동화 테스트기법인 Record Play-back 기법과 새로운 GUI 테스트 도구인 Sikuli가 등장 하였지만 기능이 추가되고 변경되는 소프트웨어를 테스팅하기 부족하다. 본 논문에서는 GUI 어플리케이션에서 점진적인 테스팅을 위해 단위 테스트인 각 테스트 케이스를 만들고 연결하는 시나리오 편집기와 시나리오 수행과 테스트 케이스 결과를 검증하는 수행 및 검증기로 구성된 자동화 테스트 도구를 설계한다.

GUI는 안정성과 견고성 그리고 사용성을 검증하기 위하여 반드시 테스트가 되어야 한다. 하지만 이러한 GUI 테스팅은 기존 소프트웨어 테스트 과정보다 복잡하고 많은 양의 테스트 작업을 요구하게 된다. 그리하여 많은 자동화된 테스트 도구가 개발 되어왔으며, 많은 산업체에서는 이러한 자동화된 테스트 도구를 사용하여 소프트웨어의 품질을 측정하고 있다. 하지만 모바일 소프트웨어의 GUI를 테스트하기 위한 도구는 현재까지 개발 중이며 많은 연구가 선행 되고 있다. 본 논문은 이러한 모바일 애플리케이션의 GUI를 테스트 하기 위하여 많이 사용되고 있는 오픈 소스 기반의 도구 3개를 선정하여 실제 애플리케이션에 적용하여 보고 분석을 통하여 향후 테스트 도구 개발에 대한 방향을 제시 하고자 한다.

A GUI automated test can be divided into two areas. The first one is a regression test automation and the second one is an automated test. The former includes generating test cases manually and executing them automatically but the latter includes both generating test cases and executing them automatically. Costs of a software test are increasing more and more. Many companies are searching for a test automation method but most used things are limited to regression test automation. So, when testing at first, there should be test cases which are drawn up by a human. This paper explains to make test cases based on a source code and execute them automatically. In this paper, the study proceeds with a digital television set-top box application and explains to test without any effort of human. Of course, this study is far from a realization to industries. But this paper has a contribution at reducing more human efforts than the previous regression test automation and showing that later, fully automated test can be possible.
