import { execSync } from 'child_process';
import fs from 'fs';
import path from 'path';
export function runCliSnapshot(cmd: string, name: string): void {
const output = execSync(cmd, { encoding: 'utf-8' });
const snapshotPath = path.join('__snapshots__', `${name}.txt`);
if (process.env.UPDATE_SNAPSHOTS) {
fs.mkdirSync(path.dirname(snapshotPath), { recursive: true });
fs.writeFileSync(snapshotPath, output);
return;
}
const expected = fs.readFileSync(snapshotPath, 'utf-8');
expect(output).toBe(expected);
