timers.runAll()

立即触发所有挂起的模拟计时器。如果 Date 对象也被模拟，它也会将 Date 对象推进到最远计时器的时间。

【Triggers all pending mocked timers immediately. If the Date object is also mocked, it will also advance the Date object to the furthest timer's time.】

下面的示例会立即触发所有待处理的计时器，使它们无需任何延迟就执行。

【The example below triggers all pending timers immediately, causing them to execute without any delay.】

import assert from 'node:assert';
import { test } from 'node:test';

test('runAll functions following the given order', (context) => {
  context.mock.timers.enable({ apis: ['setTimeout', 'Date'] });
  const results = [];
  setTimeout(() => results.push(1), 9999);

  // Notice that if both timers have the same timeout,
  // the order of execution is guaranteed
  setTimeout(() => results.push(3), 8888);
  setTimeout(() => results.push(2), 8888);

  assert.deepStrictEqual(results, []);

  context.mock.timers.runAll();
  assert.deepStrictEqual(results, [3, 2, 1]);
  // The Date object is also advanced to the furthest timer's time
  assert.strictEqual(Date.now(), 9999);
});const assert = require('node:assert');
const { test } = require('node:test');

test('runAll functions following the given order', (context) => {
  context.mock.timers.enable({ apis: ['setTimeout', 'Date'] });
  const results = [];
  setTimeout(() => results.push(1), 9999);

  // Notice that if both timers have the same timeout,
  // the order of execution is guaranteed
  setTimeout(() => results.push(3), 8888);
  setTimeout(() => results.push(2), 8888);

  assert.deepStrictEqual(results, []);

  context.mock.timers.runAll();
  assert.deepStrictEqual(results, [3, 2, 1]);
  // The Date object is also advanced to the furthest timer's time
  assert.strictEqual(Date.now(), 9999);
});拷贝

注意： runAll() 函数专门用于在定时器模拟的环境中触发定时器。它不会对真实系统时钟或模拟环境之外的实际定时器产生任何影响。
