Expand description

Single test unit struct

Fields§

§info: Option<Value>

Test info is optional.

§env: Env

Test environment configuration.

Contains the environmental information for executing the test, including block information, coinbase address, difficulty, gas limit, and other blockchain state parameters required for proper test execution.

§pre: HashMap<Address, AccountInfo>

Pre-execution state.

A mapping of addresses to their account information before the transaction is executed. This represents the initial state of all accounts involved in the test, including their balances, nonces, code, and storage.

§post: BTreeMap<SpecName, Vec<Test>>

Post-execution expectations per specification.

Maps each Ethereum specification name (hardfork) to a vector of expected test results. This allows a single test to define different expected outcomes for different protocol versions, enabling comprehensive testing across multiple Ethereum upgrades.

§transaction: TransactionParts

Transaction details to be executed.

Contains the transaction parameters that will be executed against the pre-state. This includes sender, recipient, value, data, gas limits, and other transaction fields that may vary based on indices.

§out: Option<Bytes>

Expected output data from the transaction execution.

Optional field containing the expected return data from the transaction. This is typically used for testing contract calls that return specific values or for CREATE operations that return deployed contract addresses.

Implementations§

Source§

impl TestUnit

Source

pub fn state(&self) -> CacheState

Prepare the state from the test unit.

This function uses TestUnit::pre to prepare the pre-state from the test unit. It creates a new cache state and inserts the accounts from the test unit.

§Returns

A [CacheState] object containing the pre-state accounts and storages.

Source

pub fn block_env(&self, cfg: &CfgEnv) -> BlockEnv

Create a block environment from the test unit.

This function sets up the block environment using the current test unit’s environment settings and the provided configuration.

§Arguments
  • cfg - The configuration environment containing spec and blob settings
§Returns

A configured [BlockEnv] ready for execution
