MultiTest

MultiTest is a testing tool designed to facilitate multi-contract interactions within the CosmWasm ecosystem. Its primary focus is on providing developers with a robust framework for off-chain testing of complex smart contract interactions and operations involving various Cosmos modules.

The most valuable advantages of using MultiTest is that it allows for testing and debugging smart contracts with access to the Rust source code and eliminates the need to run a complete blockchain node to begin designing the functionality of the contract. Additionally, MultiTest enables the execution of tests significantly faster than on a real blockchain, as it bypasses the overhead associated with network consensus and block production. This results in a more efficient development cycle, allowing for quicker iterations and faster identification of issues, even before the smart contract is deployed on the blockchain.

While MultiTest is a blockchain SIMULATOR, it may happen, that the behavior of the real blockchain might slightly differ in some edge cases.
