I came across this library on y news, and thought id give it a bit of a test. 

I managed to get it working but not really sure what tests it can do. 

I set it to take a screen shot of a webpage, I guess its automated testing of websites for what exactly? do you tell it to click on the links and that kind of thing?

Installation

Just update everything if you are using brew on mac. 

brew update / brew upgrade

Then you can install playwrite with 

npm init playwright 

add the test script

import { test, expect } from '@playwright/test';

test('basic test', async ({ page }) => {
  await page.goto('https://playwright.dev/');
  const title = page.locator('.navbar__inner .navbar__title');
  await expect(title).toHaveText('Playwright');
});

then run it with this

npx playwright test 

After Installation

✔ Success! Created a Playwright Test project at /Users/../code/playwrite
Inside that directory, you can run several commands:

  npx playwright test
    Runs the end-to-end tests.

  npx playwright test --project=chromium
    Runs the tests only on Desktop Chrome.

  npx playwright test tests/example.spec.js
    Runs the tests of a specific file.

  npx playwright test --debug
    Runs the tests in debug mode.

We suggest that you begin by typing:

  npx playwright test

And check out the following files:
  - ./tests/example.spec.js - Example end-to-end test
  - ./playwright.config.js - Playwright Test configuration
