COMPUTER USE / WORKFLOW

Test signup, login, and checkout flows

Exercise synthetic journeys with deterministic acceptance checks and isolated test state.

Before the first run

  • An approved test environment and synthetic accounts
  • Test payment fixtures or a non-charging checkout mode
  • Expected assertions and cleanup rules
ACTION BOUNDARY

Define what the agent can do.

Synthetic accounts and test transactions only. Production messages, real payments, and live customer data are excluded.

The implementation sequence

  1. 01

    Prepare isolated fixtures

    Create distinct accounts or reset state so parallel runs cannot change one another’s data. Confirm the target URL is the approved test environment.

  2. 02

    Run the primary journey

    Exercise signup, login, cart changes, and checkout with explicit assertions about visible state and persisted test records.

  3. 03

    Run failure scenarios

    Test invalid inputs, expired sessions, rejected test payments, and repeated clicks. Assert that errors are understandable and a rejected operation does not create an accepted order.

  4. 04

    Explore within a charter

    Optionally give an agent a bounded exploratory task. Record its path and treat findings as hypotheses until reproduced with a clear expected result.

  5. 05

    Verify cleanup and report

    Confirm synthetic records and accounts are reset according to policy. Attach traces for failures and separate application defects from fixture or transport failures.

Stop for human approval

Approve the environment and fixture scope. Any expansion to production or real external effects requires separate authorization.
