Abstract

In this paper, we propose a software testing environment, called D-Cloud, using cloud computing technology and virtual machines with fault injection facility. Nevertheless, the importance of high dependability in a software system has recently increased, and exhaustive testing of software systems is becoming expensive and time-consuming, and, in many cases, sufficient software testing is not possible. In particular, it is often difficult to test parallel and distributed systems in the real world after deployment, although reliable systems, such as high-availability servers, are parallel and distributed systems. D-Cloud is a cloud system which manages virtual machines with fault injection facility. D-Cloud sets up a test environment on the cloud resources using a given system configuration file and executes several tests automatically according to a given scenario. In this scenario, D-Cloud enables fault tolerance testing by causing device faults by virtual machine. We have designed the D-Cloud system using Eucalyptus software and a description language for system configuration and the scenario of fault injection written in XML. We found that the D-Cloud system, which allows a user to easily set up and test a distributed system on the cloud and effectively reduces the cost and time of testing.
