Expand description

Contains for fuzz testing

Fields§

§runs: u32

The number of test cases that must execute for each property test

§max_test_rejects: u32

The maximum number of test case rejections allowed by proptest, to be encountered during usage of vm.assume cheatcode. This will be used to set the max_global_rejects value in proptest test runner config. max_local_rejects option isn’t exposed here since we’re not using prop_filter.

§seed: Option<U256>

Optional seed for the fuzzing RNG algorithm

§dictionary: FuzzDictionaryConfig

The fuzz dictionary configuration

§gas_report_samples: u32

Number of runs to execute and include in the gas report.

§failure_persist_dir: Option<PathBuf>

Path where fuzz failures are recorded and replayed.

§failure_persist_file: Option<String>

Name of the file to record fuzz failures, defaults to failures.

§show_logs: bool

show console.log in fuzz test, defaults to false

§timeout: Option<u32>

Optional timeout (in seconds) for each property test
