First test in JavaScript

A complete Playwright test in Node.js you can copy, run, and watch on a real browser.

One file. Copy it, put your access key in, run it, and watch it happen in your dashboard.

What you need

Node 18 or newer, and Playwright itself:

npm install playwright

Nothing of ours to install. This is the ordinary Playwright library.

The whole test

// first-test.js
const { chromium } = require("playwright");
const { randomUUID } = require("crypto");

const ACCESS_KEY = "xyz_your_access_key_here";
const TEST_NAME = "example.com opens";

const capabilities = {
  browserName: "chrome",
  browserVersion: "latest",
  "testkase:options": {
    accessKey: ACCESS_KEY,
    platformName: "windows 11",
    name: TEST_NAME,
    build: "first-test",
    runId: randomUUID(),
    recording: true,
  },
};

(async () => {
  const browser = await chromium.connect(
    `wss://hub.testkase.com/playwright?capabilities=${encodeURIComponent(JSON.stringify(capabilities))}`,
  );

  const page = await browser.newPage();
  await page.goto("https://example.com");

  const title = await page.title();
  if (!title.includes("Example Domain")) {
    throw new Error(`wrong title: ${title}`);
  }
  console.log("  title:", title);

  await browser.close();
  console.log("PASS ", TEST_NAME);
})();

What each part does

Six things carry the whole file. Read down the middle column and you have its shape.

	The part	What it does
1	`wss://hub.testkase.com/playwright?capabilities=…`	Where everything goes. Playwright has no capability argument, so the whole object is URL-encoded onto the connect address.
2	`accessKey`	Signs you in. Copy it from the Access key page. There is no username here — the key is the only credential.
3	`platformName`	Which operating system. Set it. Leave it out and Chrome, Edge and Firefox fall back to `linux`, which no machine of ours runs, so the session is refused.
4	`recording: true`	Says what to keep. `name` is how you will recognise the session in a list; `recording` is the video, and you get none unless you ask. Every option.
5	`chromium.connect(...)`	Ordinary Playwright from here on. Every command behaves exactly as it does locally — we only carry it to the browser and back. You call `chromium.connect` whichever brand you asked for; the address decides what you get.
6	`browser.close()`	Ends the session and frees the machine. Forget it and the session runs until a timeout stops it — which you are paying for.

Run it

node first-test.js

The browser opens on our machines, not yours. Open your dashboard while it runs and the session is there live; when it ends, the video is on it.
