Atomico is a small library for the creation of interfaces based on web-components, only using functions and hooks.

import { h, useEffect } from "../../core/core";
import { customElementScope } from "../utils";

describe("useEffect", () => {
    it("initialize state", async done => {
        function Wc() {
            useEffect(() => {
                expect(true).toBeTruthy();
                return () => {
                    expect(true).toBeTruthy();
                    done();
                };
            });
            return <host />;
        }

        let node = customElementScope(Wc);

        document.body.appendChild(node);

        await node.rendered;

        node.remove();
    });
