无法为变量

Question

var readline = require('readline');
var test
rl = readline.createInterface(process.stdin, process.stdout);
rl.question('What is your favorite food?', function(answer) {
 console.log('Oh, so your favorite food is ' + answer);
 test = answer
});
rl.close()

webdriverio
 .remote(options)
 .init()
 .url('http://www.google.com')
 console.log(test) //undefined, why?

所以我不明白为什么它向我显示“未定义”而不是我通过终端输入的字符串。那是为什么？

我的猜测是不同步，但如何让它同步？

Answer 1

1. 已安装：https://www.npmjs.com/package/readline-sync

2. 修改了代码：

   var readlineSync = require('readline-sync');
   var test
   
   webdriverio
    .remote(options)
    .init()
    .url('http://www.google.com').then(function() {
      test = readlineSync.question('What is your favorite food?'); //Honeyberry
      console.log(test) //Honeyberry
    })
