Why did you have to write a wat by hand?

- pallet-contracts' unit tests also use wat instead of full Rust contract compiled to wasm
- no need for compiling contract to wasm / no need to keep obscure bytes
- kinda readable
- you don't have to encode any selectors or arguments:
data: vec![]works well for calling the only method
drink/test-resources/transfer.wat
Outdated

Doesn't matter in this context of course xD

and tests were passing? How's that po(a)ssible? ie how was the event emitted if the txn failed? Or at this level the event emition is not yet affecting what ends up in the final block?

okay, taking that back - I have no idea why it was passing

Adding tests for ContractAPI. Also, bump version to 1.3 - it should be now ready to fill the gaps in ink!
