AI Coding Assistants Need Browser Acceptance, Not Just a Green Build
Connect code review, browser checks and safe payment validation in a practical development workflow.
A generated change can compile while leaving a button disabled, a layout overflowing or a payment callback unable to grant the right benefit. Treat an AI coding assistant as part of the development process, with a clear acceptance step for the user-facing behavior.
Describe behavior before code
Write a short before-and-after requirement. For example, an optional verification step must not prevent a valid form from submitting. Specify what must happen on success, failure and cancellation. This gives the assistant an observable target and gives reviewers a useful checklist.
Review the proposed change
Inspect the affected files and server-side rules. A UI change that removes a disabled state is incomplete if the API still rejects the same request. Use the Cursor profile to explore an assistant workflow, then confirm current product behavior in its documentation.
Choose meaningful tests
Test the behavior that could break: a skipped optional field, a wrong owner, a duplicate callback or a failed network call. Avoid tests that merely repeat implementation details. Keep fixtures separate from production data so failures do not create real purchases or listings.
Open the actual page
Check a desktop layout and a narrow mobile layout. Click the primary action, verify the visible result and inspect errors. Playwright documentation describes browser testing tools; an automated pass should still correspond to the requirement you wrote.
Separate payment checks
A mocked successful callback checks application logic. A payment test environment checks provider integration. A real paid order checks the complete live flow. State which level passed; an HTTP 200 on a page does not prove that money arrived or an entitlement was delivered.
Record the practical result
Document what changed, the checks performed and any remaining gap. Use links to the affected product pages or workflow instructions. In ToolNav, good acceptance connects the submission form, checkout and resulting listing rather than treating them as unrelated pages.
Example: optional verification
Write acceptance cases for an optional backlink step: the user skips it, verification fails, the service times out and verification succeeds. Every otherwise valid free submission should enter the review queue. Verify the button state and the server response separately. On an invalid form, keep the entered data and identify the field to fix. This is a small example of a larger principle: the displayed requirement and the actual backend rule must agree.
Example: a three-tier checkout
For a multi-tier listing, record the server price, checkout product, paid order and delivered placement. Check that a lower plan cannot obtain a higher entitlement by changing a browser field. Replay a successful callback and confirm it does not create another listing. A mock event validates these application rules, but it does not prove live receipt of money. Keep the payment test environment and the real transaction audit clearly identified in the result.
Review the uncomfortable states
Test cancellation, expired sessions, permission failures and incomplete network calls. Look for a saved draft, an understandable message and a safe retry route. Inspect narrow screens with long labels, not only a clean desktop sample. If the build passes but one of these states cannot be completed, keep the task open. The user needs a usable workflow across ordinary interruptions, not just a successful demonstration under ideal conditions.
A practical delivery note
Summarize the observable change, the checks that passed and any step that still needs a real account or transaction. Link to the affected screen and explain the remaining condition in plain language. Save the test cases alongside the change so a future edit can replay them. Avoid reporting a page status or a test count as evidence for a different claim; each result should support the behavior it actually exercises.
