praxis-cli 0.2.0

//! The three paths every `praxis-cli` integration test starts from: the binary
//! under test, the workspace root, and this crate's fixture tree.
//!
//! **Why they live here and not in `praxis-test-support`.**
//! `CARGO_BIN_EXE_praxis` is set by cargo only while compiling *this* package's
//! integration tests, so `bin_path` has to expand the literal inside one of
//! them; a helper crate would see no such variable. The other two follow it
//! rather than being split across two homes.

// Every test binary compiles this whole module and calls part of it, so the
// items a given file does not use are dead *there* and nowhere else — and
// `just ci` runs clippy with `-D warnings`.
#![allow(dead_code)]
