In-Memory Testing
Zero-port unit testing with Vitest and Node:test using app.fetch(Request).
Froot implements standard Web fetch(Request) natively, enabling test suites to run completely in-memory without opening TCP sockets or colliding ports.
Testing with Vitest or Node:test
ts
import { describe, it } from 'node:test';
import assert from 'node:assert/strict';
import { app } from '../src/app.js';
describe('API Tests', () => {
it('GET /health returns 200', async () => {
const res = await app.fetch(new Request('http://localhost/health'));
assert.equal(res.status, 200);
const data = await res.json();
assert.equal(data.status, 'ok');
});
});
