Module runner 

The runner module

Structs

Env

Container for EVM environment (cfg + block) and transaction.

TestRunner

Runs test macros on Foundry’s executor, with its cheatcodes, tracer and log collector.

Constants

DEFAULT_INITIAL_BALANCE 🔒

Foundry’s default --initial-balance: 2^96 - 1 wei

Functions

apply_env_overrides 🔒

Sets the transaction and block fields a test overrides, on top of the runner’s environment

call_base_gas 🔒

Intrinsic gas of a call transaction to another account, excluding calldata and access lists

cheats_config

Settings for Foundry cheatcodes in hnc test. A failed vm.assert* reverts, as in forge test, so the test stops there and the failure survives a vm.revertToState.

db_error 🔒

Wraps a database failure as a runner error

decode_hex 🔒

Decodes hex the runner was given, such as compiled code or calldata, naming it in the error

huff_functions 🔒

Where each outlined function of the compiled test starts, so traces can show its calls

outcome_of 🔒

How a call ended, with Foundry’s exit reason turned back into the EVM’s halt reason, so OutOfGas covers every kind of out-of-gas halt

skipped_result 🔒

The result of a test a skip flag skips, which does not run

use_sender_nonce 🔒

Sends the next transaction of the sender with its current nonce
