//! Test helpers shared by the `run` and scenario test modules.
//!
//! Feature-gated at the `mod` declaration in `commands/mod.rs` to the
//! union of the caller features (`security` for `run_tests.rs`,
//! `integration-http` for the scenario tests) so minimal-feature test
//! builds see no dead code.

/// Deliver an exchange to a `direct:` endpoint exactly as the scenario
/// harness `DirectStimulus` does (crates/camel-integration-test
/// adapters.rs): a fresh endpoint + producer per send through the
/// component registry, one `oneshot` per exchange, retrying the
/// consumer-startup race (`EndpointCreationFailed`) on a bounded
/// deadline.
