environment.
import { mock } from 'node:test';
const fn = mock.fn();fn(1,2,3); // does nothing... but
console.log(fn.mock.callCount()); // Records how many times it was calledconsole.log(fn.mock.calls[0].arguments)); // Recoreds the arguments that were passed each callThe full MockTracker API is documented in the Node.js documentation for MockTracker ↗.
