@tysel/test

Test helpers for applications running under tysel test. This package does not provide a Node.js test runner.

tysel init adds the matching version automatically. For a manual installation:

version="$(tysel --version | awk '{print $2}')"
npm install --save-dev "@tysel/test@$version"

import app from "../src/index.ts";
import { assert, invokeFetch, test } from "@tysel/test";

test("returns a greeting", async () => {
  const response = await invokeFetch(app.fetch, "http://localhost/hello");
  assert.equal(response.status, 200);
  assert.deepEqual(await response.json(), { message: "hello" });
});

Run tests with tysel test. Each test file executes in a fresh QuickJS isolate. invokeFetch calls a Fetch handler without opening a listener; invokeFetchWithRuntime additionally injects a focused capability mock. The package version must match the native toolchain.

See the testing API.
