testing-conventions 0.0.26

//! Integration tests for the Rust packaging slice (#74): exercise the
//! `packaging::inspect` library API over pre-built `cargo package` **crate
//! tarball** fixtures (`.crate`). Rule (README "Packaging"): the source tarball
//! must not ship the crate-root `tests/` directory.
//!
//! The e2e suite (`packaging_crate_e2e.rs`) drives the same crates through the
//! built binary; this checks the library contract — `inspect` unpacks the
//! `.crate` (a gzipped tar) and the `tests/` directory pattern flags files under
//! the crate-root `tests/`.
