Running shell scripts that have contain sudo commands in them from jenkins might not run as expected. To fix this, follow along
Simple steps:
1. On ubuntu based systems, run " $ sudo visudo "
2. this will open /etc/sudoers file.
3. If your jenkins user is already in that file, then modify to look like this:

5. Exit by doing Ctrl+X
6. Relaunch your jenkins job

生成随机范围的数字，字符串等

export  default (quantity,minChar = 5,maxChar = 10,fn) => {
  let randomArray = [];
  while (randomArray.length < quantity){
    let num = Math.ceil(Math.random()*minChar*(maxChar/minChar));
    if (num >= minChar) randomArray.push(fn(num));
  }
  return randomArray;
