//! Helpers shared by the integration tests that assert over config files.
//!
//! Integration tests are separate crates, so this is the only sharing point
//! they have short of the library's public API - and the reader below has
//! already been transcribed once. `src/test_support.rs` is the wrong home: it
//! is `pub(crate)` and holds mock-endpoint fixtures.
/// A config file from the repository root, with its comment lines stripped.
///
/// The generated files carry an explanatory comment above every key, so a
/// raw-text assertion would be satisfied by the comment describing a setting
/// as readily as by the setting.
