안드로이드의 인텐트를 이용하여 주소록 어플리케이션에서 이메일 어플리케이션을 실행시킬 수 있다. 또한 어플리케이션 동작 중 배터리 부족 경고 또는 충전 케이블이 연결됨과 같은 시스템에서 브로드캐스트를 발생시킨다. 다른 어플리케이션의 컴포넌트를 실행시키고 시스템의 브로드캐스트를 처리하는 모든 것이 컴포넌트들 간의 상호작용이다. 컴포넌트들 간의 상호작용이 올바르게 이루어지지 않을 경우 다른 어플리케이션이 시작되거나, 보안상의 문제점 등이 발생할 수 있다. 본 논문에서는 위와 같은 문제점을 발견하기 위해 인텐트 기반의 안드로이드 상호작용 테스트를 위한 테스트 시나리오를 설계하는 기법에 대한 연구이다. 어플리케이션 내부의 컴포넌트 상호작용에 사용되는 명시적 인텐트와 다른 어플리케이션 또는 시스템의 컴포넌트들과의 상호작용에 사용되는 암시적 인텐트를 함께 고려하여 인텐트 목록을 생성하고 컴포넌트 상호작용 테스팅에 사용할 테스트 시나리오를 생성한다.

Android applications are composed of one or more components. The components within an application or several applications may interact with each other primarily through intents. Such interactions may cause security and reliability issues such as broadcast theft, activity hijacking, and intent spoofing. These problems need to be resolved through testing techniques using various interaction test scenarios before an application gets launched. However, with the existing test scenario generation approach, some infeasible test scenarios may be generated since they do not consider the re-execution order based on activity setting when pressing the back button. This paper proposes a test case generation technique which removes infeasible interaction paths by utilizing the activity stack information.

Using the intent of the Android application, an application can execute other application's components. However, if interaction between these components are not processed normally, such problems as incorrect component execution and unhandled system broadcast may be occurred. In this paper, to generate test scenarios for inter application interaction, a testing approach is proposed using a merged intent list and a single merged diagram. The proposed method can effectively be carried out to check the abnormal interaction among the applications which was not considered in existing testing approaches.

Graphical user interface testing (GUI testing) techniques have been widely used to test the functionality of Android applications (apps) and to detect faults for verification of the reliability and usability of apps. To adequately test the behaviors of apps, a number of studies on model-based GUI testing techniques have been performed on Android apps. However, the effectiveness of model-based techniques greatly depends on the quality of the GUI model, because model-based GUI testing techniques generate test inputs based on this model. Therefore, in order to improve testing effectiveness in model-based techniques, accurate and efficient GUI model generation has to be achieved using an improved model generation technique with concrete definition of GUI states. For accurate and efficient generation of a GUI model and test inputs, this study suggests a hierarchical GUI state comparison technique and evaluates this technique through comparison with the existing model-based techniques, considering activities as GUI states. Our results show that the proposed technique outperforms existing approaches and has the potential to improve the performance of model-based GUI testing techniques for Android apps.

The context-awareness of mobile applications yields several issues for testing, since mobile applications should be able to be tested in any environment and under any contextual input. In previous studies of testing for Android applications as an event-driven system, many researchers have focused on using generated test cases considering only Graphical User Interface (GUI) events. However, it is difficult to find failures that could be detected when considering the changes in the context in which applications run. It is even more important to consider various contexts since the mobile applications adapt and use the new features and sensors of mobile devices. In this paper, we provide a method of systematically generating various executing contexts from permissions. By referring to the lists of permissions, the resources used by the applications for running Android applications can be easily inferred. To evaluate the efficiency of our testing method, we applied the method on two open source projects and showed that it contributes to improve the statement code coverage.

안드로이드 어플리케이션은 인텐트를 이용하여 다른 어플리케이션의 컴포넌트를 실행시킬 수 있다. 이러한 상호작용이 정상적으로 호출되거나 처리되지 않으면 기대한 컴포넌트가 실행되지 않는 등의 문제점이 발생할 수 있다. 본 논문에서는 이와 같은 어플리케이션간의 상호작용 문제점을 검사하기 위해 어플리케이션들의 소스코드와 매니페스트 파일로부터 컴포넌트 다이어그램과 인텐트 목록을 각각 추출하여 결합된 액티비티 다이어그램을 생성하고 이로부터 테스트 시나리오를 생성하는 기법을 제안한다.

Most Android applications are being developed by one or a few person without professional testing team. In such a poor development environment, applications may contain severe errors which may also affect the Android platform. In order to detect these errors, the behaviors of Android activities should be identified by considering user-defined lifecycle as well as the system-defined one. This paper proposes a method to generate test scenarios based on the both of user-defined and system-defined activity lifecycle of Android GUI applications. The test scenarios are generated by a state diagram extracted from the source code and are transformed into Jython scribes by using GUI layout information for automatically performing testing.
