//! Shared scaffolding for the integration test suites in
//! `wdotool/tests/`. Each `cli_*.rs` test crate brings this in via
//! `mod common;` and uses it to build a `DispatchCtx` over a
//! `MockBackend` plus capture buffers, run a parsed command, and
//! return the recorded call sequence + captured stdout/stderr.
//!
//! The single entry point is [`run`]: pass the argv you'd pass to the
//! CLI (with or without the leading `wdotool`), and it returns
//! everything the test needs to assert on.
