Today's information systems have become large and complex because they must interact with each other via networks. This makes testing and assuring the dependability of systems much more difficult than ever before. DS-Bench Toolset has been developed to address this issue, and it includes D-Case Editor, DS-Bench, and D-Cloud. D-Case Editor is an assurance case editor. It makes a tool chain with DS-Bench and D-Cloud, and exploits the test results as evidences of the dependability of the system. DS-Bench manages dependability benchmarking tools and anomaly loads according to benchmarking scenarios. D-Cloud is a test environment for performing rapid system tests controlled by DS-Bench. It combines both a cluster of real machines for performance-accurate benchmarks and a cloud computing environment as a group of virtual machines for exhaustive function testing with a fault-injection facility. DS-Bench Toolset enables us to test systems satisfactorily and to explain the dependability of the systems to the stakeholders.
