Simulating a Failed Transaction Due to Slippage

In decentralized trading, transactions can fail if the price moves beyond the user’s set slippage tolerance. This test intentionally sets a very low slippage tolerance (e.g., 0.1%) for a swap on a volatile token pair. The transaction should be broadcast but then fail on the blockchain. MetaMask must detect this failure and reflect it clearly in the activity feed. The status should change to «Failed,» and tapping on the transaction should provide more details about the reason for the failure, such as «price slippage too high.» This provides crucial feedback to the user, helping them understand why their transaction did not go through and adjust their parameters accordingly. Handling failure states gracefully is as important as handling success. Analysis of common transaction failures is a valuable resource available on metamask to help users avoid them in the future. The test passes if the failure is communicated clearly and promptly, turning a potentially frustrating experience into a learning opportunity and preventing users from repeatedly attempting the same failed transaction and wasting gas fees in the process.
