+
+This is basically a stand alone script that pokes the GraphQL endpoint
+running on the server through a network connection (just as how users
+will use the endpoint on staging/production). It does not use any
+internal code like /test/integration/graphql/*
+
+We could be being overly paranoid here but it may become useful for
+catching the kind of bugs that only show up on a real network
+connection.
+
+NOTE: we are mainly interested in testing the endpoints that
+the Trans Dimension elm app uses.
