Unit tests for Move contracts use test functions with the #[test] attribute to validate individual functions and resource handling. Aptos Move testing supports signing, account simulation, and resource assertions—run tests with aptos move test to verify contract logic before deployment.

Multi-signer testing in Move requires setting up multiple accounts and simulating signed transactions within integration tests. Use mock-data scenarios and account fixtures to authorize operations across signers and verify permissions and state changes across accounts.

Move Prover integrates with Aptos to formally verify contract invariants and specifications. Define specs and run aptos move prove to check contract correctness mathematically, complementing unit and integration tests for comprehensive coverage.

Comprehensive test coverage combines unit tests for individual functions, integration tests for workflows, and Move Prover for formal specs. Use debugging techniques to trace execution paths and ensure all contract behaviors—normal flows, edge cases, and resource constraints—are tested.

Resource testing in Move requires patterns for account creation, balance assertions, and overdraft prevention. Integration tests should simulate realistic workflows with proper account setup, signed transactions, and state validation to ensure resource operations behave correctly.
