//! Shared helpers for runtime integration tests.
//!
//! Cargo's integration test runner compiles each `.rs` file under `tests/` as
//! its own crate, so helpers live under `tests/common/mod.rs` and are brought
//! in with `mod common;` from each test file. Individual tests may use a
//! subset of these helpers, which is why the module allows `dead_code`.
