Browser e2e test authentication can be established by registering and logging in users via API, then injecting the resulting session cookies or state directly into the browser context. This approach avoids ad-hoc bypasses and ensures protected pages are reliably tested.

Session injection in browser testing is the process of loading an authenticated session state, typically via API-generated cookies, directly into the browser context. This allows tests to bypass the login UI and immediately access protected pages.

To test protected pages requiring login in e2e tests, you establish an authenticated session beforehand by logging in via API and injecting the session cookies into the browser context. This prevents test failures due to unauthenticated access.

When direct session injection is not supported by the testing tool, the best approach is to document manual login procedures or implement test-only bypasses. You must ensure any mocks or bypasses are reverted when the test concludes.

Yes, you can use API calls, such as curl with cookie jars, to register and log in users. The API-generated session state or cookies are then loaded into the browser context to authenticate your end-to-end tests.

E2e tests fail on protected pages when the authenticated session is not properly established or injected into the browser context. Establishing the session via API and loading the correct cookies before navigating prevents unauthenticated access failures.
