First test in Python

A complete Playwright test in Python 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

Python 3.8 or newer, and Playwright itself:

pip install playwright

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

The whole test

# first_test.py
import json
import uuid
from urllib.parse import quote

from playwright.sync_api import sync_playwright

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

capabilities = {
    "browserName": "chrome",
    "browserVersion": "latest",
    "testkase:options": {
        "accessKey": ACCESS_KEY,
        "platformName": "windows 11",
        "name": TEST_NAME,
        "build": "first-test",
        "runId": str(uuid.uuid4()),
        "recording": True,
    },
}

with sync_playwright() as p:
    ws = f"wss://hub.testkase.com/playwright?capabilities={quote(json.dumps(capabilities))}"
    browser = p.chromium.connect(ws)

    page = browser.new_page()
    page.goto("https://example.com")

    title = page.title()
    assert "Example Domain" in title, f"wrong title: {title}"
    print("  title:", title)

    browser.close()
    print("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	`p.chromium.connect(ws)`	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

python first_test.py

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.
