Automated testing is critical for the complex products development and manufacture. In generally, connecting multiple test environments in geographical distributed environment to share resources is a way to reduce cost. However, it conflicts with the principle of "keep test environment clean". Moreover, high latency between geographical different networks may impact origin automated test activities in reality. In this paper, we propose an automated testing framework for geographical distributed testing environment to solve the problems of sharing resources. In the proposed framework, improved Test Harness (TH) and integrated Test as a Service (TaaS) are proposed to assure automated testing flow and guarantee test integrity. The proposed framework may not impact origin automated test activities, which could reduce the cost of test activities in really. In addition, a basic implementation of Test Harness and TaaS Console in the proposed framework are presented in this paper.

To appropriately realize the performance of a web service, it is essential to give it a comprehensive testing. Although an elastic test could be guaranteed in traditional cloud testing systems, the geographical test that supports real user behavior simulation remains a problem. In this paper, we propose a testing system based on a crowdsourcing model to carry out the distributed test on a target web server automatically. The proposed crowdsourcing-based testing system (CTS) provides a reliable testing model to simulate real user web browsing behaviors with the help of web browsers scattered all around the world. In order to make the entire test process the same as the real situation, two test modes are proposed to simulate real user activity. By evaluating every single resource of web service automatically, a tester can not only find out internal problems but also understand the performance of the web service. In addition, the complete geographical test is available with the performance measurements coming from different regions in the world. Several experiments are performed to validate the functionality and usability of CTS. It demonstrates that CTS is a complete and reliable web service testing system, which provides unique functions and satisfies different requirements.

Ethereum smart contract makes developers can deploy decentralized applications to inherit features from blockchain, such as decentralization and openness. Although Ethereum provided a decentralized platform, Ethereum Virtual Machine for smart contracts, it lacks of ability to fetch off-chain data. The general solution is Oracle data carrier. However, Oracle results in rising deployment costs. It requires Ethereum smart contract developers to follow format in programing contract, this constraint decreases the readability of smart contract. This paper proposes an off-chain data fetching architecture which is cost-effective and highly elastic for smart contract. It also compatible with exited contract, which makes Ethereum smart contract owner able to automate the reply process.
