Acceptance test
Also called Gherkin
A test written from what the customer asked for and not from how the code works. Often written in Given, When, Then sentences that a person can read and a tool can run.
It is written before the code exists and from the request, so it is harder for the agent to fit it to whatever it happened to build. A person can also read it and say "that isn't what I meant" before any code gets written.
Say it to your agent
“Before writing any code, write features/refund.feature in Gherkin: Given an order paid yesterday, When the customer asks for a refund, Then the status is refunded and the money is returned once. Stop and let me approve it.”
