GraphQL::Relay::Walker is a Ruby library that generates queries for walking a Relay GraphQL schema. Given a GraphQL::Schema, you can walk from a given starting point, exercising any defined connections. This can be useful for various kinds of automated testing. Check out the GitHub Walker example to see it in action.Requiring graphql/relay/walker/client_ext will add a GraphQL::Client#walk method. This simplifies things by allowing the client to build and execute the query for you.
