gqls-cli 0.14.0

//! Live-endpoint introspection smoke test.
//!
//! This hits a public GraphQL API over the network, so it is `#[ignore]`d by
//! default — a plain `cargo test` stays offline and hermetic. Run it now and
//! then (or when touching the URL/introspection path) with:
//!
//!     cargo test --test http_introspection -- --ignored
//!
//! Target: the Countries API (https://countries.trevorblades.com) — a small,
//! stable, auth-free public schema.
