Managing Highly Concurrent, State-Dependent Playwright Sessions

说明与用途

使用 Playwright 的 BrowserContext 进行隔离和清理：在 beforeEach 中创建上下文，在 afterEach 中关闭，并通过 API 调用删除后端数据。

问题

Large-scale Playwright E2E load tests for stateful processes (login, cart, checkout) on distributed CI/CD leave dirty backend and browser state, causing flaky failures.

结果

State isolation and cleanup achieved with BrowserContext and test hooks, eliminating flaky failures and improving test speed.

工作流

• Create a new BrowserContext in test.beforeEach
• Set up test data (e.g., register user) and login within the context
• Run the test steps in the isolated context
• In test.afterEach, close the BrowserContext
• Make API calls (DELETE /api/user/{id}) to clean backend data

证据

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

来源

Creating new BrowserContext instances is far more efficient than launching a full browser per test.
