Imagine thousands of concurrent e-commerce journeys, where a single test failure poisons your CI/CD. Here’s how to guarantee state isolation and cleanup.

Large-scale Playwright E2E load tests for stateful processes (login, cart, checkout) on distributed CI/CD face critical issues.

• This pollutes subsequent tests, causing flaky, inexplicable failures.

• Goal: Achieve absolute isolation and guaranteed cleanup efficiently, without full browser relaunch per test.

Leverage Playwright's BrowserContext for isolation and robust test hooks for setup/teardown.
