Source

pub fn spec_id(&self) -> SpecId

Returns the spec id of the executor

Source

pub async fn get_fork_material( config: &Config, evm_opts: EvmOpts, ) -> Result<(Env, Option<CreateFork>, Option<Chain>, bool)>

Methods from Deref<Target = Executor>§

Source

fn clone_with_backend(&self, backend: Backend) -> Self

Source

pub fn backend(&self) -> &Backend

Returns a reference to the EVM backend.

Source

pub fn backend_mut(&mut self) -> &mut Backend

Returns a mutable reference to the EVM backend.

Source

pub fn env(&self) -> &Env

Returns a reference to the EVM environment.

Source

pub fn env_mut(&mut self) -> &mut Env

Source

pub fn set_spec_id(&mut self, spec_id: SpecId)

Sets the EVM spec ID.

Source

pub fn gas_limit(&self) -> u64

Returns the gas limit for calls and deployments.

This is different from the gas limit imposed by the passed in environment, as those limits are used by the EVM for certain opcodes like gaslimit.

Source

pub fn set_gas_limit(&mut self, gas_limit: u64)

Sets the gas limit for calls and deployments.

Source

pub fn legacy_assertions(&self) -> bool

Source

pub fn set_trace_printer(&mut self, trace_printer: bool) -> &mut Self

Source

pub fn create2_deployer(&self) -> Address

Source

pub fn deploy( &mut self, from: Address, code: Bytes, value: U256, rd: Option<&RevertDecoder>, ) -> Result<DeployResult, EvmError>

Deploys a contract and commits the new state to the underlying database.

Executes a CREATE transaction with the contract code and persistent database state modifications.

Source

pub fn deploy_with_env( &mut self, env: EnvWithHandlerCfg, rd: Option<&RevertDecoder>, ) -> Result<DeployResult, EvmError>

Deploys a contract using the given env and commits the new state to the underlying database.

§Panics

Source

pub fn setup( &mut self, from: Option<Address>, to: Address, rd: Option<&RevertDecoder>, ) -> Result<RawCallResult, EvmError>

Calls the setUp() function on a contract.

This will commit any state changes to the underlying database.

Ayn changes made during the setup call to env’s block environment are persistent, for example vm.chainId() will change the block.chainId for all subsequent test calls.

Source

pub fn call( &self, from: Address, to: Address, func: &Function, args: &[DynSolValue], value: U256, rd: Option<&RevertDecoder>, ) -> Result<CallResult, EvmError>

Performs a call to an account on the current state of the VM.

Source

pub fn transact( &mut self, from: Address, to: Address, func: &Function, args: &[DynSolValue], value: U256, rd: Option<&RevertDecoder>, ) -> Result<CallResult, EvmError>

Performs a call to an account on the current state of the VM.

Source

pub fn call_raw( &self, from: Address, to: Address, calldata: Bytes, value: U256, ) -> Result<RawCallResult>

Performs a raw call to an account on the current state of the VM.

Source

pub fn call_raw_with_authorization( &mut self, from: Address, to: Address, calldata: Bytes, value: U256, authorization_list: Vec<SignedAuthorization>, ) -> Result<RawCallResult>

Performs a raw call to an account on the current state of the VM with an EIP-7702 authorization list.

Source

pub fn transact_raw( &mut self, from: Address, to: Address, calldata: Bytes, value: U256, ) -> Result<RawCallResult>

Performs a raw call to an account on the current state of the VM.

Source

pub fn call_with_env(&self, env: EnvWithHandlerCfg) -> Result<RawCallResult>

Execute the transaction configured in env.tx.

The state after the call is not persisted.

Source

pub fn transact_with_env( &mut self, env: EnvWithHandlerCfg, ) -> Result<RawCallResult>

Execute the transaction configured in env.tx.

Source

fn commit(&mut self, result: &mut RawCallResult)

Commit the changeset to the database and adjust self.inspector_config values according to the executed call result.

This should not be exposed to the user, as it should be called only by transact*.

Source

pub fn is_raw_call_mut_success( &self, address: Address, call_result: &mut RawCallResult, should_fail: bool, ) -> bool

Returns true if a test can be considered successful.

This is the same as Self::is_success, but will consume the state_changeset map to use internally when calling failed().

Source

pub fn is_raw_call_success( &self, address: Address, state_changeset: Cow<'_, StateChangeset>, call_result: &RawCallResult, should_fail: bool, ) -> bool

Returns true if a test can be considered successful.

This is the same as Self::is_success, but intended for outcomes of Self::call_raw.

Source

pub fn is_success( &self, address: Address, reverted: bool, state_changeset: Cow<'_, StateChangeset>, should_fail: bool, ) -> bool

Returns true if a test can be considered successful.

If the call succeeded, we also have to check the global and local failure flags.

These are set by the test contract itself when an assertion fails, using the internal fail function. The global flag is located in CHEATCODE_ADDRESS at slot GLOBAL_FAIL_SLOT, and the local flag is located in the test contract at an unspecified slot.

This behavior is inherited from Dapptools, where initially only a public failed variable was used to track test failures, and later, a global failure flag was introduced to track failures across multiple contracts in ds-test#30.

The assumption is that the test runner calls failed on the test contract to determine if it failed. However, we want to avoid this as much as possible, as it is relatively expensive to set up an EVM call just for checking a single boolean flag.

See:

Source

fn is_success_raw( &self, address: Address, reverted: bool, state_changeset: Cow<'_, StateChangeset>, ) -> bool

Source

fn build_test_env( &self, caller: Address, transact_to: TxKind, data: Bytes, value: U256, ) -> EnvWithHandlerCfg

Creates the environment to use when executing a transaction in a test context

If using a backend with cheatcodes, tx.gas_price and block.number will be overwritten by the cheatcode state in between calls.
