Module testing 

Available on crate feature testing only.

Provides test utilities for working with accounts and account IDs within the Miden network. This module is only available when the testing feature is enabled.

Modules

account_id

asserts

Assertion macro for note-lifecycle checks in tests.

commonstd

executor

feestd

Funding support for running the test helpers against a fee-charging chain.

mock

note_transport

standards

Raw access to miden-standards testing modules for items not curated by miden-client.

utils

Macros

assert_execution_error

Asserts that a Result<_, ExecError> failed as expected.

assert_note_created

Asserts the tx emitted a note matching the spec. Fields are optional; unset ones are skipped.

assert_transaction_executor_error

Same as assert_execution_error!, but for TransactionExecutorError. The matches and $expected arms unwrap TransactionProgramExecutionFailed(_) and match against the inner ExecutionError.

Structs

ClientDataStore

Wrapper structure that implements DataStore over any Store.

ExecError

A newtype wrapper around ExecutionError that provides better error messages by using PrintDiagnostic for display formatting.

MockChain

The MockChain simulates a simplified blockchain environment for testing purposes.

MockChainBuilder

A builder for a MockChain’s genesis block.

MockTransaction

Represents all needed data for executing a transaction, or arbitrary code.

MockTransactionBuilder

A builder for a MockTransaction that is coupled to a concrete MockChain.

NoteBuilder

Enums

AccountState

Helper type for increased readability at call-sites. Indicates whether to build a new (nonce = ZERO) or existing account (nonce = ONE).

Auth

Specifies which authentication mechanism is desired for accounts

MockChainNote

Represents a note that is stored in the mock chain.

MockTransactionInput

Helper type to abstract over the account input to MockChain::build_transaction. See that method’s docs for details.

Traits

DataStore

The data store the executor reads from, along with the trait whose methods it serves. Exposed here so that tests can exercise it on its own, without going through a transaction or a note screening pass. The DataStore trait defines the interface that transaction objects use to fetch data required for transaction execution.
