camel-integration-test 0.46.0

//! Partner scripting end to end (ADR-0069 sections 5, 8, 9).
//!
//! The first file-run proof of the shipped address/bindVar stack: a
//! YAML string loads through the crate's document path, partners bind
//! (scripted where the document declares a `partners:` entry,
//! permissive otherwise), `fill_bind_vars` writes the bound authority
//! into the scenario variables, and the whole document runs through
//! [`run_scenario_document`]. The assertions inspect the partner's
//! recorder — a literal `:0` dial cannot produce a recorded arrival,
//! so a recording is the proof the send reached the bound address.
//!
//! The helper mirrors the CLI driver's partner mapping (status
//! default 200, headers default empty, body through the client send
//! path's `value_to_wire` encoding) at the library level. The
//! scenarios exercise the client-role wire path
//! only — except the two-layer test, which boots one route the same
//! way the CLI driver does, to prove the env-tier binding form.
