Tests for the AtomicAssets smart contract written using the Hydra Testing Framework
The abi / wasm files in the contract source are the compiled atomicassets contract with the added hydraload action that is needed for the Hydra testing framework. Read more here: https://docs.klevoya.com/hydra/guides/initial-contract-tables
If you want to compile the contract source manually, the hydra-include-helper.txt lists all the changes that need to be applied to the atomicassets header file, as well as adding the hydra.hpp to the include folder.
