Version 0.2.0

scenario

Define and test CLI behavior scenarios under controlled terminal conditions.

scenario provides infrastructure for running CLI applications across different terminal environments — with or without a TTY, at various terminal widths, with or without color support.

Quick Start

use scenario::{Scenario, Terminal};

// Run a command with piped stdio (no TTY)
let output = Scenario::new("echo")
    .arg("hello")
    .run()
    .unwrap();
assert!(output.stdout().contains("hello"));

// Run in a real PTY with specific dimensions
let output = Scenario::new("my-cli")
    .args(["--help"])
    .terminal(Terminal::pty(80, 24))
    .run()
    .unwrap();

// Interactive session
let mut session = Scenario::new("my-cli")
    .args(["init"])
    .terminal(Terminal::pty(80, 24))
    .spawn()
    .unwrap();
session.expect("Choose:").unwrap();
session.send_line("default").unwrap();
let output = session.wait().unwrap();
