Efficiently Manage Authenticated User Sessions Across Multiple Playwright Tests

Описание и применение

Оптимизируйте выполнение E2E‑тестов в Playwright, выполняя вход в систему один раз и сохраняя состояние браузера с помощью storageState. Затем применяйте сохранённое состояние к каждому тесту, экономя время и повышая надёжность.

Задача

Repetitive logins in Playwright E2E tests cause performance bottlenecks, increase flakiness, and complicate maintenance.

Результат

Significant reduction in test execution time, improved test isolation, and easier maintenance by decoupling login logic from individual tests.

Рабочий процесс

• Create a global-setup script that logs in once and saves the browser context state to a file using page.context().storageState({path: AUTH_FILE}).
• Configure playwright.config.ts to use the saved storageState for all tests by setting use.storageState to the same file path.
• Run the test suite; Playwright will load the pre-authenticated state for each test, providing a clean context without re‑logging in.
• Maintain the global-setup script if login credentials or flow change, then re‑run the setup to update the state file.

Доказательства

Playwright's storageState feature is your answer. It captures browser context (cookies, local storage, session storage) and lets you reuse it.
