Embedded systems have high coupling and dependency among different hardware and software components in heterogeneous layers, which makes location and issue tracking in their testing difficult. Despite these poor verification conditions, even the most important reliability quality verification among embedded system characteristics is verified with insufficient sample size, typical test cases, and general test strategies, following limitations such as development costs and scheduling. As a result, shipments are highly likely to lead to various reliability quality problems because items have not been verified considering reliability quality characteristics. Hence, to address this gap, this study developed remote embedded device test framework on the cloud (RED-TFC), which has an innovative reliability test manager component that can automatically perform various tests for the evaluation of reliability and performance of distributed shared devices by utilizing the cloud concept. RED-TFC offers two key enhancements over existing testing services: (i) the adaptive sample scale for reliability test (ASRT), a feature that identifies the most appropriate sample size for performing functionality and reliability tests of remote verification targets connected to the RED-TFC server; and (ii) the mass sample reliability test (MSRT), which uses a test case that is specific to reliability, with the sample size obtained by ASRT, to perform verification following the Markov prediction process. This paper analyses two Android smartphone models considered the most generic examples, including many embedded components, and presents a method of detecting a high number of reliability problems in smartphones using the proposed RED-TFC and its implications.

云端远程嵌入式设备测试框架

嵌入式系统在异构层中的不同硬件和软件组件之间具有高度耦合和依赖性，这使得其测试中的定位和问题跟踪变得困难。尽管验证条件很差，但即使是嵌入式系统特性中最重要的可靠性质量验证，也是在样本量不足、典型测试用例和通用测试策略不足、开发成本和进度安排等限制的情况下进行验证的。因此，出货很可能会导致各种可靠性质量问题，因为项目尚未考虑可靠性质量特性进行验证。因此，为了弥补这一差距，本研究开发了云端远程嵌入式设备测试框架（RED-TFC），它具有创新的可靠性测试管理器组件，可以利用云概念自动执行各种测试，用于评估分布式共享设备的可靠性和性能。RED-TFC 提供了对现有测试服务的两个关键增强功能：(i) 可靠性测试的自适应样本量表 (ASRT)，该功能可确定最合适的样本量，以执行连接到 RED 的远程验证目标的功能和可靠性测试- TFC服务器；(ii) 大规模样本可靠性测试（MSRT），它使用特定于可靠性的测试用例，以 ASRT 获得的样本量，按照马尔可夫预测过程进行验证。本文分析了被认为是最通用的两个 Android 智能手机型号，包括许多嵌入式组件，
