CTT: Load Test Automation for TOSCA-based Cloud Applications

Despite today's fast and rapid modeling and deployment capabilities to meet customer requirements in an agile manner, testing is still of utmost importance to avoid outages, unsatisfied customers, and performance problems. To tackle such issues, (load) testing is one of several approaches. In this paper, we introduce the Continuous Testing Tool (CTT), which enables the modeling of tests and test infrastructures along with the cloud system under test, as well as deploying and executing (load) tests against a fully deployed system in an automated manner. CTT employs the OASIS TOSCA Standard to enable end-to-end support for continuous testing of cloud-based applications. We demonstrate CTT's workflow, its architecture, as well as its application to DevOps-oriented load testing and load testing of data pipelines.
