Function withHarness

withHarness<T>(
spec: HarnessTestSpec,
fn: (r: HarnessTestResult) => T | Promise<T>,
): Promise<T>
Run a harness test, hand the result to fn, and always clean up the sandbox. Returns whatever fn returns. Use this instead of calling cleanup() by hand — it survives assertion failures.
