Fixes #14525 We didn't have the Orderbook thoroughly tested as when I implemented it TXE was not yet reasonable. Now it's reasonable so I decided to tackle this. Since AI is known to be good at tests I decided to gave it a try. ## AI experiment This was the prompt + well curated the context window by opening the relevant tabs in Cursor: > write the orderbook tests in noir-projects/noir-contracts/contracts/app/orderbook_contract/src/test.nr > > note that the Orderbook contract accepts 2 token contracts on the input so you will need to deploy those first. Use the setup and setup and mint functionality from noir-projects/noir-contracts/contracts/app/token_contract/src/test/utils.nr. > > From the orderbook you want to test the setup order and create order functions. There is also already a yarn-project/end-to-end/src/e2e_orderbook.test.ts test but that is written in TypeScript and noit Noir and it tests only the happy path. In the Noir tests I would also like to test unhappy paths. See tests in noir-projects/noir-contracts/contracts/app/token_contract/src/test/transfer_in_private.nr for inspiration on how to structure the Noir tests. Overall it managed to implement it all. The only thing I need to help it with is that it didn't understand that it needs to refer the `token_contract` crate when deploying: ```diff env.deploy("Token") env.deploy("@token_contract/Token") ``` Would say this was caused by us not having enough examples and me not putting that into a context window. Other than this it managed to resolve on its own one other issue (tried to mint with an account with token minter permissions). The only other thing I did is that I nuked quite a few tests it did because it was for example testing that a function call fails when it doesn't have token transfer authwit provided. Felt like this is sufficient to have only in the token tests. ### Update on AI Code quality was not great and had to redo quite a lot of stuff. That could be improved though if we had a proper reference (plenty of the style issues were present in the rest of our codebase).
