Struct near_sdk::MockedBlockchain

pub struct MockedBlockchain { /* fields omitted */ }

Mocked blockchain that can be used in the tests for the smart contracts. It implements BlockchainInterface by redirecting calls to VMLogic. It unwraps errors of VMLogic to cause panic during the unit test similarly to how errors of VMLogic would cause the termination of guest program execution. Unit tests can even assert the expected error message.
