An airplane is composed by many complexes and embedded systems. During the integration testing phase, the design office produces requirements of the targeted system, and the test center produces concrete test procedures to be executed on a test bench. In this context, integration tests are mostly written in natural language and manually executed step by step by a tester. In order to formalize integration tests procedures dedicated to each system with domain specific languages approved by testers, and in order to automatize integration tests, we have introduced agile practices in the integration testing phase. We have chosen a Behavior Driven Development (BDD) approach to orchestrate Domain Specific Test Languages produced for the ACOVAS FUI project.
