@opentf/web-test

A testing utility for OTF Web, inspired by Testing Library. It renders components into a real DOM (happy-dom), compiles JSX through the framework's own compiler, and bundles @testing-library/dom queries plus user-event.

bun add -d @opentf/web-test

Why it fits OTF Web

• Real DOM, real compiler. Components run exactly as they ship — no mock renderer.

• Signals, not snapshots. Updates are surgical, so you assert on the DOM after an interaction with no act() wrapper or manual flush.

• Familiar API. The Testing Library queries and user-event you already know.

At a glance

import { test, expect } from "bun:test";
import { render, userEvent } from "@opentf/web-test";
import Counter from "./Counter.jsx";

test("increments on click", async () => {
  const { getByRole } = render(Counter);
  const user = userEvent.setup();
  await user.click(getByRole("button"));
  expect(getByRole("button").textContent).toBe("Count: 1");
});

The API Reference lists every export.
