Methods and devices for performing off-chain testing on smart contract

A device for performing an off-chain testing on a smart contract, comprising:

• one or more processors;
• and
• one or more computer-readable memories coupled to the one or more processors and having instructions stored thereon that are executable by the one or more processors, wherein the one or more processors are configured to:
• generate execution environment information for the smart contract, the execution environment information including at least one of transaction context information, blockchain information, or state information;
• provide an interface between the generated execution environment information and the smart contract;
• execute the smart contract based on the generated execution environment information and the provided interface;
• and
• store an execution result of the smart contract, wherein storing the execution result comprises storing data indicating a change in at least one of the blockchain information or the state information,
• wherein generating the execution environment information, providing the interface, executing the smart contract, and storing the execution result of the smart contract are performed before the smart contract is deployed into a blockchain, thereby implementing the off-chain testing on the smart contract.

A non-transitory computer-readable medium having stored therein instructions that, when executed by a processor of a device, cause the device to perform a method for performing an off-chain testing on a smart contract, the method comprising:

• generating execution environment information for the smart contract, the execution environment information including at least one of transaction context information, blockchain information, or state information;
• providing an interface between the generated execution environment information and the smart contract;
• executing the smart contract based on the generated execution environment information and the provided interface;
• and
• storing an execution result of the smart contract, wherein the storing the execution result comprises storing data indicating a change in at least one of the blockchain information or the state information,
• wherein the generating the execution environment information, the providing the interface, the executing the smart contract, and the storing the execution result of the smart contract are performed before the smart contract is deployed into a blockchain, thereby implementing the off-chain testing on the smart contract.
