Question

我正在使用NightWatch框架运行我的e2e测试

在测试中，我需要检查浏览器显示的值以重置为定义的初始值，设置为从config.js文件导出的常量

但是我收到SYNTAX错误，是不是被接受了？

Starting selenium server... started - PID:  49634
There was an error while starting the test runner:
../test/e2e/specs/test.js:4
import { WORKING_TIME } from '@/config';
^^^^^^

config.js

let coeff = process.env.NODE_ENV === 'testing' ? 0.5 : 1
export const WORKING_TIME = coeff * 60

E2E / test.js

import { WORKING_TIME } from '@/config'

module.exports = { 
    'check STOP event': (browser) => {
    const devServer = browser.globals.devServerURL
    browser.url(devServer).waitForElementVisible('#app', 5000)
    browser.click('[title=start]').waitForElementVisible('i.toggle-volume', 5000)

    // CLICK on STOP button
    browser.click('[title=stop]').pause(1000)
    ...
    // Check timer is reset
    const leftPad = (str, length = 10) => {
      return `${' '.repeat(length)}${str}`
    }
    const min = Math.floor(WORKING_TIME / 60)
    const sec = WORKING_TIME % 60
    const initialTimer = leftPad(min, 2) + ':' + leftPad(sec, 2)
    browser.expect.element('.my-timer').text.to.equal(initialTimer)
    browser.end()
  }
}

Answer 1

正如@Omran所说，我遇到了ES6问题......

1 - 需要在导入之前插入（并且还要写一个正确的路径......）

<强> E2E / test.js

require('babel-core/register')
import { WORKING_TIME } from '../../../config'

2 - e2e test runner.js正在设置：

process.env.NODE_ENV = 'testing'

我应该把它添加到.babelrc

.babelrc

{
  "presets": [
    ["env", {
      "modules": false,
      "targets": {
        "browsers": ["> 1%", "last 2 versions", "not ie <= 8"]
      }
    }],
    "stage-2"
  ],
  "plugins": ["transform-runtime"],
  "env": {
    "test": {
      "presets": ["env", "stage-2"],
      "plugins": ["istanbul"]
    },
    "testing": {
      "presets": ["env", "stage-2"],
      "plugins": ["istanbul"]
    }
  }
}

Vue.js可以在e2e测试中导入模块吗？导入时出现语法错误
