This program is an Anchor implementation of the Dutch Auction, where the auction is instantiated with a start date, end date and starting price. The current price decreases linearly over the duration of the auction from the starting price to zero. This implementation auctions a token (or tokens).
Run tests using anchor test from inside the root directory.
| Test | Purpose | Notes |
|---|---|---|
| Initialization | Establishes two wallets, funds them, and mints tokens to wallet1. These tokens are the 'assets' that will be auctioned. |
Isn't a test, rather establishes the testing environment. |
| Can initialize auction | wallet1 instantiates an auction using the initialize_auction method. |
|
| Auction instantiator can close the auction. | Closes the auction account using the close_auction method. Returns the token back to the instantiator of the auction and refunds rent exemption. |
|
| Can bid on an auction | wallet2 bids on a 1 minute auction after 15 seconds. |
Margin of error set to 5% to account for transaction fees, refunding rent, etc. |
| Cannot bid on auction before it begins | Checks constraint for bidding on an auction before it starts | |
| Cannot bid on an auction after it ends | Checks constraint for bidding on an auction after it ends | |
| Cannot instantiate an auction with a start date in the past | Checks constraint that auction must start after initialization | |
| Must provide valid date range for the auction | Checks constraint that start date must precede end date | |
| Auction can only be closed by the instantiator | Checks constraint that only the instantiator of the auction can close it | |
| Must pass auction owner into bid | Checks constraint that bids must be sent to the instantiator of the auction, rather than another wallet |
