virtual-tty-pty

PTY integration for virtual-tty - run real processes in virtual terminals for integration testing.

Features

• Real Process Execution: Run actual terminal applications (vim, less, bash) in virtual terminals
• PTY Integration: Uses pseudo-TTY for realistic terminal emulation
• Input/Output Control: Send input and capture output from running processes
• Integration Testing: Test your CLI tools against real terminal applications

Usage

use virtual_tty_pty::PtyAdapter;
use std::process::Command;

// Create a PTY adapter
let mut pty = PtyAdapter::new(80, 24)?;

// Spawn a command
let mut child = pty.spawn_command(
    Command::new("echo").arg("Hello from PTY!")
)?;

// Wait for completion
child.wait()?;

// Get the output
println!("{}", pty.get_snapshot());

Interactive Sessions

use virtual_tty_pty::PtyAdapter;
use std::process::Command;

let mut pty = PtyAdapter::new(80, 24)?;
let mut child = pty.spawn_command(Command::new("bash"))?;

// Send commands
pty.send_input_str("echo 'Hello'\n")?;
pty.send_input_str("ls -la\n")?;
pty.send_input_str("exit\n")?;

child.wait()?;

Platform Support

This crate requires Unix-like systems (Linux, macOS) due to PTY API dependencies.

Use Cases

• Integration testing with real terminal applications
• Validating ANSI escape sequence handling
• Testing interactive CLI tools
• Automating terminal-based workflows
