Simple and complete CLI testing utilities that encourage good testing practices.

import type { ChildProcessWithoutNullStreams } from "node:child_process";

export interface TestInstance {
  clear: () => void;
  process: ChildProcessWithoutNullStreams;
  stdoutArr: Array<{ contents: Buffer | string; timestamp: number }>;
  stderrArr: Array<{ contents: Buffer | string; timestamp: number }>;
  getStdallStr: () => string;
  hasExit: () => null | { exitCode: number };
  debug: (maxLength?: number) => void;
}

declare global {
  const jest: undefined | any;
  const vi: undefined | any;
  const afterEach: undefined | ((fn: () => void) => void);
  const teardown: undefined | ((fn: () => void) => void);
  const expect: undefined | any;
