@microsoft/tui-testyarn add -D @microsoft/tui-test
import { test, expect } from '@microsoft/tui-test';
test.use({ program: { file: 'node', args: ['./my-cli.js'] } });
test('selects option and proceeds', async ({ terminal }) => {

await terminal.write('\x1B[B'); // Arrow Down
await terminal.submit(); // Enter
await expect(terminal.getByText('Option 2 selected')).toBeVisible();
});
test('matches snapshot', async ({ terminal }) => {
await expect(terminal).toMatchSnapshot();
});
// Navigation
await terminal.write('\x1B[A'); // Arrow Up
await terminal.write('\x1B[B'); // Arrow Down
await terminal.write('\x1B[C'); // Arrow Right

await terminal.submit(); // Enter
await terminal.write('\t'); // Tab
await terminal.write('\x03'); // Ctrl+C
await terminal.write('\x1B'); // Escape
await terminal.write('\x7F'); // Backspace
await terminal.write('hello'); // Type text
// Assertions
await expect(terminal.getByText('pattern')).toBeVisible();
await expect(terminal.getByText('pattern', { full: true })).toBeVisible();
await expect(terminal).toMatchSnapshot();
// Reading
const content = terminal.content; // Full terminal content as string
npx tui-test # Run all tests
npx tui-test --update-snapshots # Update snapshots
