Module testing 

Testing utilities for click-rs applications.

This module provides utilities for testing CLI applications built with click-rs. The main component is CliRunner, which allows invoking commands with captured output for assertions.

Reference

Based on Python Click’s testing.py.

Example

use click::testing::CliRunner;
use click::command::Command;

let cmd = Command::new("hello")
    .callback(|_ctx| {
        // Your command logic here
        Ok(())
    })
    .build();

let runner = CliRunner::new();
let result = runner.invoke(&cmd, &[]);

assert_eq!(result.exit_code, 0);
assert!(result.is_success());
