// Example showing how to migrate from TempDir to TestHomeGuard
mod common;
use assert_cmd::Command;
use common::TestHomeGuard;
// OLD PATTERN (using TempDir directly)
/*
use tempfile::TempDir;
use std::fs;
use std::path::{Path, PathBuf};
fn setup_test_home() -> (TempDir, PathBuf) {
let temp_dir = TempDir::new().unwrap();
let kopi_home = temp_dir.path().join(".kopi");
fs::create_dir_all(&kopi_home).unwrap();
(temp_dir, kopi_home)
}
#[test]
fn test_old_pattern() {
let (_temp_dir, kopi_home) = setup_test_home();
let mut cmd = Command::cargo_bin("kopi").unwrap();
cmd.env("KOPI_HOME", kopi_home.to_str().unwrap());
cmd.arg("list");
cmd.assert().success();
}
*/
// NEW PATTERN (using TestHomeGuard)
#[test]
fn test_new_pattern() {
// Create test home with random 8-character directory under target/home
let test_home = TestHomeGuard::new();
let test_home = test_home.setup_kopi_structure();
let kopi_home = test_home.kopi_home();
let mut cmd = Command::cargo_bin("kopi").unwrap();
cmd.env("KOPI_HOME", &kopi_home);
cmd.arg("list");
cmd.assert().success();
// Cleanup happens automatically when test_home is dropped
}
// Benefits of TestHomeGuard:
// 1. Creates directories under target/home/<random-8-chars>/ instead of system temp
// 2. Automatically sets up .kopi directory structure
// 3. Provides consistent cleanup on drop
// 4. Uses 8-character random names as requested
// 5. Less boilerplate code needed in each test
