@harnessed-ts/dom

Testing Library driver for @harnessed-ts/core. Framework-agnostic — it queries the DOM, so it has no React dependency and works with any Testing Library setup.

import { dom } from "@harnessed-ts/dom"
import "@harnessed-ts/dom/matchers"

render(<LoginForm />)
const form = new LoginFormHarness(dom({ user: userEvent.setup() }))

Pass container to scope a harness to one tree — which is what makes two instances in a single test, and portals, work without a cleanup race.

Full guide, the cross-driver guarantees, and the API: the harnessed README.
