XReq – Executable Requirements for DO-178B – is the latest project to join the Open-DO initiative. XReq, first contributed by Sogilis, is a tool designed to help testing and verifying a project. It has been specifically adapted for the DO-178B context but can be used by a much wider audience. To help DO-178B projects, it bring together the tests (HLT/LLT) with their requirements, thus helping traceability of the tests.
