@stefanjudis Playwright can do this?
Does anyone remember this friend?
Or this one?

The idea of end-to-end testing was great!
But it was terrible.
Tests were slow, hard to write and fl aky.
We run the tests on demand. My colleagues & I
We gave up. :/ My colleagues & I
Things got a lot better
Playwright is cross-everything
Playwright is cross-everything
Run your tests in VS Code
Very solid typings
More than a browser control / / @ts - check
import { test, expect } from "@playwright/test"; test.describe("navigation", () = > { test.beforeEach(async ({ page }) = > { / / Go to the starting url before each test. await page.goto("https: / / playwright.dev/"); }); test("main navigation", async ({ page }) = > { / / Assertions use the expect API. await expect(page).toHaveURL("https: / / playwright.dev/"); }); });
Easy to parallelize npx playwright test - - workers 4
/ / playwright.conf i g.js import { def i neConf i g } from '@playwright/test'; export default def i neConf i g({ workers: process.env.CI ? 2 : undef i ned, })
Built for quick execution const button = page.locator('button') await button.click()
await expect(button).toBeHidden() Auto-wait and web- fi rst assertions make waitFor statements redundant.
A very fast release cycle
Let's have a look!
