The Testing Workgroup will be responsible for the creation, review and approval of testing documentation, checklists and use cases. The workgroup will determine interoperability testing requirements to enable robust testing of information exchange among participants of the eHealth Exchange for Coordinating Committee approved use cases. Under the advice and guidance of the Coordinating Committee, and with approval from the Specification Factory and Policy and Technical Task Group, the Testing Workgroup will be responsible for testing requirements to ensure interoperable exchange among differing technology platformsand architectures. The Testing Workgroup shall focus on the broad needs for industry and remain grounded in existing capabilities implemented in production and where there are gaps or issues with information exchange.
