fault

Signature

faultcore.fault(policy_name: str = "auto")

Purpose

Applies a registered policy by name. With "auto", resolves the current thread policy.

Defaults and validation

• If no resolved policy exists, wrapped function executes without injected profile.

Example (named test profile)

import faultcore


faultcore.register_policy(name="slow_api", latency="100ms", packet_loss="1%")


@faultcore.fault("slow_api")
def request_api() -> int:
    return 200


def test_named_policy_application() -> None:
    status = request_api()
    assert status == 200
