为什么我的脚本不能正确迭代？

Question

脚本运行良好，但我希望它运行不止一次。我把我认为完全正常的基本 for 循环放在了整个脚本的顶部。

而不是多次运行脚本，它只是将脚本的每个动作加倍，例如。如果我将迭代变量设置为 2，它只会通过脚本执行每个操作两次，而我希望它从头到尾运行整个脚本两次。

const puppeteer = require('puppeteer');
const C = require('./constants');
var USERNAME_SELECTOR;
var PASSWORD_SELECTOR;
var PHONE_SELECTOR;
var CTA_SELECTOR;
const URLL = process.argv[2];
var iterations = process.argv[3];
var usernameFieldWasFound = false;
var passwordFieldWasFound = false;
var buttonWasFound = false;
var phoneFieldWasFound = false;

for (i = 0; i < iterations; i++) {

Answer 1

您所做的是声明并立即运行所有函数iterations 次，并且它们并行运行。

尝试将所有内容声明一次，然后只运行主函数需要多少次：

(async () => {
  for (i = 0; i < iterations; i++) {
    await playTest(URLL);
  }
  process.exit(1);
})();

另外请注意，process.exit(1) 中的 1 表示“错误”，而这基本上是指“脚本失败”。
