Playwright-Session

Playwright-Session UI visualizes a recorded Playwright session in a UI containing:

• Video from the session,
• DOM HTML Viewer,
• Network Requests Viewer,
• Console Viewer,
• Playwright actions listed in console view to easily understand what your script was doing,

Recording Session

To record your own Playwright session, start by adding this package to your project:

npm install playwright-session --save-dev

Once you have the package installed, you need to initialize your playwright script with the recorder:

import { chromium } from "playwright";
import initializeRecorder from "playwright-session";
 
(async () => {
  const browser = await chromium.launch();
 
  // Recorder is initalizing required events collection,
  // to later be able to replay a Playwright session in the UI.
  // Session file, that can be loaded in the UI,
  // will be saved to ./vuetify-session-events.ldjson
  const { page, context } = await initializeRecorder(
    browser,
    "vuetify-session-events"
  );
 
  await page.goto("https://vuetifyjs.com/en/");
 
  await page.evaluate(() => console.log("Adding sample console log 1"));
  await page.evaluate(() => console.warn("Adding sample console log 2"));
  await page.evaluate(() => console.info("Adding sample console log 3"));
  await page.evaluate(() => console.error("Adding sample console log 4"));
  await page.evaluate(() => console.debug("Adding sample console log 5"));
 
  await page.click('a[href="/en/getting-started/quick-start/"]');
 
  await page.click('text="UI Components"');
 
  await page.click('text="Form inputs & controls"');
 
  await page.click('text="Forms"');
 
  await page.waitForSelector('#usage .v-example input[type="text"]');
 
  const inputs = await page.$$('#usage .v-example input[type="text"]');
 
  await page.click("#usage h2");
 
  // Adding timeouts here, to show down Playwright,
  // and make recorded session a bit smoother.
  await new Promise((r) => setTimeout(r, 1000));
 
  await inputs[0].fill("Welcome");
  await new Promise((r) => setTimeout(r, 500));
  await inputs[1].fill("To");
  await new Promise((r) => setTimeout(r, 500));
  await inputs[2].fill("Playwright-Session");
 
  await new Promise((r) => setTimeout(r, 3000));
 
  await browser.close();
})();

Replaying Session

Once you have your session file recorded, head over to the Playwright-Session UI, upload your session file by clicking on the Upload button in the top-left corner of the UI, and play your session. You can also provide a link to your custom session file via a query string parameter like this: https://playwright-session.hotdata.co/?session_url=https://playwright-session.hotdata.co/vuetify-session-events.ldjson.
