Every Playwright test gets a fresh browser context, so login has to be replayed or stored

Playwright creates a new BrowserContext for each test, so cookies, localStorage, sessionStorage and permissions never leak between tests. That isolation is what makes fullyParallel safe, and it also means a login performed in one test is invisible to the next, and a beforeAll hook cannot log in for a whole file.

The supported pattern is to authenticate once in a setup project, call page.context().storageState({ path: 'playwright/.auth/user.json' }), and point use: { storageState: ... } at that file for the dependent projects. Keep the file out of version control, since it holds live session cookies. When roles differ, write one state file per role and select it per project or per test with test.use({ storageState }). Tests that must run signed out override it with an empty state object rather than clearing cookies by hand.
