How can an AI agent perform browser-based manual QA?

An AI agent can perform exploratory browser QA when its environment provides authorized browser-control tools. It interacts with the rendered application, follows user journeys, observes results, and records failures. This exercises the experience from the user's perspective instead of evaluating source code alone.

Prepare a reproducible test environment

Use a known application revision, a stable test URL, and synthetic accounts. Define the roles to exercise and the expected starting state. For wedding onboarding, prepare one new organizer, one returning organizer, and an account without access to another test wedding.

Keep tests away from real invitation recipients or production records unless those actions are explicitly authorized. If the environment cannot complete a required external step, record that limitation rather than reporting the entire journey as passed.

Follow journeys and inspect transitions

A useful onboarding run starts at the homepage, opens signup, submits valid data, completes wedding details, reaches the dashboard, logs out, and signs in again. Check that entered information persists and that a returning user avoids duplicate onboarding.

Then explore failures: missing fields, rejected credentials, a slow request, a refreshed protected page, and direct navigation after logout. Inspect both visible feedback and relevant browser errors when the tools provide them.

Observe the interface after each action. Repeatedly clicking without checking the current state can hide a broken transition or create duplicate test data.

Report evidence rather than broad assurance

For each finding, record the starting conditions, actions, expected result, and actual result. A screenshot can show misplaced validation text, while reproduction steps explain how it appeared.

Distinguish browser exploration from automated regression tests and from a dedicated security assessment. Human testing remains valuable for confusing language, visual judgment, and workflows the agent missed.

After a fix, repeat the affected journey against the updated revision. Report which paths were verified and which remained unavailable or untested.
