testing-conventions 0.0.15

//! E2E tests for the packaging rule's foundation (#70): drive the built CLI
//! binary against fixture "artifact" trees and assert the exit code. The rule
//! (README "Packaging"): test files must never ship in a built artifact. Each
//! fixture stands in for an unpacked built artifact (a wheel, a `dist/`).
//!
//! These start red — the `packaging` command does not exist yet, so the binary
//! exits with a usage error rather than `1`/`0` — and go green once the command
//! and the scanner land.
