/**
 * A convenience wrapper on top of `addMocksToSchema`. It adds your mock resolvers
 * to your schema and returns a client that will correctly execute your query with
 * variables. Note: when executing queries from the returned server, context and
 * root will both equal `{}`.
 * @param schema The schema to which to add mocks. This can also be a set of type
 * definitions instead.
 * @param mocks The mocks to add to the schema.
 * @param preserveResolvers Set to `true` to prevent existing resolvers from being
 * overwritten to provide mock data. This can be used to mock some parts of the
 * server and not others.
