End-to-end tests that secure real user flows in the browser.
Playwright drives real browsers and runs complete user journeys automatically, across Chromium, Firefox and WebKit. Auto-waiting waits for elements and stable states on its own, which makes the flaky tests of earlier tools largely disappear. Trace viewer, screenshots and videos show you exactly what happened in the browser when something fails. So before every release we check whether the truly important paths, from sign-in to checkout, actually work, before they ever reach a visitor.
More in the documentationFor a project's business-critical paths we write end-to-end tests in Playwright and hook them into CI, so every merge runs them. If checkout or login breaks, you learn it from a red build with a trace, not from a support email. Right where a bug costs the most, that gives you a hard safety net.
import { test, expect } from "@playwright/test";
test("user can sign in", async ({ page }) => {
await page.goto("/login");
await page.getByLabel("Email").fill("ada@example.com");
await page.getByLabel("Password").fill("hunter2");
await page.getByRole("button", { name: "Sign in" }).click();
await expect(page.getByRole("heading", { name: "Dashboard" })).toBeVisible();
});Good to know
Lean on the built-in auto-waiting and role-based locators like getByRole instead of adding fixed waits and brittle CSS selectors. For logged-in tests save the auth state once via storageState and skip the login in every single spec.
