//! Shared helpers for integration tests.
//!
//! Pulled in from `tests/integration.rs` via `mod common;`. Not all
//! integration test files use every helper — the `allow(dead_code)` knobs
//! below silence the per-binary unused-warning noise that Cargo emits when a
//! helper is referenced by some tests but not others.
// `setup` wires `ctor::ctor` / `ctor::dtor` hooks that spawn and reap the
// vendored test_server once per test binary. Merely `mod`ing it is enough to
// activate the hooks — nothing else imports from it.
