The IMDEA Software Institute will participate in a newly funded Horizon 2020 EU project called ElasTest: an elastic platform for testing complex distributed large software systems. The ElasTest project will develop infrastructure to help developers test and validate “software in the large”, while maintaining compatibility with current practices and tools. ElasTest will use a combination of instrumentation, test orchestration and test recommendation specifically crafted for improving the software reliability in the large software and in particular for cloud applications. The ElasTest consortium involves 11 companies, universities, and research centers from 6 European countries. The IMDEA Software Institute involvement focuses on runtime verification (Dr. César Sánchez) and security (Dr. Juan Caballero). The project will launch on January 2017 and will last for 3 years.
