Expand description

Builds Madsim Runtime with custom configuration values.

Fields

seed: u64

The random seed for test.

count: u64

The number of tests.

jobs: u16

The number of jobs to run simultaneously.

config: Config

The configuration.

time_limit: Option<Duration>

The time limit for the test.

check: bool

Enable determinism check.

Implementations

Create a new builder from the following environment variables:

  • MADSIM_TEST_SEED: Set the random seed for test.

    By default, the seed is set to the seconds since the Unix epoch.

  • MADSIM_TEST_NUM: Set the number of tests.

    The seed will increase by 1 for each test.

    By default, the number is 1.

  • MADSIM_TEST_JOBS: Set the number of jobs to run simultaneously.

    By default, the number of jobs is 1.

  • MADSIM_TEST_CONFIG: Set the config file path.

    By default, tests will use the default configuration.

  • MADSIM_TEST_TIME_LIMIT: Set the time limit for the test.

    The test will panic if time limit exceeded in the simulation.

    By default, there is no time limit.

  • MADSIM_TEST_CHECK_DETERMINISM: Enable determinism check.

    The test will be run at least twice with the same seed. If any non-determinism detected, it will panic as soon as possible.

    By default, it is disabled.

Run the future with configurations.
