Python

Native PyO3 bindings over the Rust core, shipped as an abi3 wheel for CPython 3.9 and newer. No system dependencies.

pip install wickra-strategy-ci

import json
from wickra_strategy_ci import Session

session = Session()

response = json.loads(session.command(json.dumps({
    "cmd": "run_suite",
    "tests": tests,                 # a list of StrategyTest objects
    "data": {"BTCUSDT": candles},   # dataset_ref -> list of candles
})))

print(response["passed"], "passed,", response["failed"], "failed")
for result in response["results"]:
    for diff in result["diff"]:
        print(result["id"], diff["field"], diff["expected"], "->", diff["actual"])

Session.version() returns the core version. The session owns no state between commands — tests and data travel with each call — so one session can serve a whole run.

The boundary

Every binding exposes the same two things: a Session, and one call that takes a command envelope as JSON and returns the response as JSON. The commands are run_test, run_suite, bless, list and version, and the response bytes are identical in every language — that is what the golden corpus pins.

Errors in the request — an unknown command, a malformed test — come back in-band as {"ok":false,"error":…}, because they are data about the request rather than a failure of the call.
