Ask Certyn

Ask about current app behavior in plain English. Certyn answers from its live knowledge of your app — what's passing, what's failing, and what changed since the last run.

What happens when a user applies an invalid discount code?

Based on the last regression run (2h ago): applying an invalid code at /checkout returns a 500 error instead of a validation message. The cart total stays unchanged and no error is shown to the user.

1 failing · Bug #47 open

Is the invite flow working?

Yes — user invite flow is passing in all 3 scenarios (send invite, accept invite, role assignment). Last verified 4 hours ago.
