Question

我使用vue-cli项目（安装了electronic + seleniumWebDriver）与ChromeDriver一起运行测试。

我继续运行chromedriver（安装在vue-cli项目中），然后运行测试文件“ node ff.js”。

Electron应用程序在屏幕上运行，但未发生任何反应。然后等到该进程退出，结果变为错误“ UnhandledPromiseRejectionWarning：WebDriverError：未知错误：DevToolsActivePort文件不存在”。

我在网上搜索了一下，发现其他人认为它可以正常工作的解决方案。它只是在chrome选项中添加了“ --disable-dev-shm-usage”。但这仍然是错误的。

ff.js

const webdriver = require('selenium-webdriver')
const chrome = require('selenium-webdriver/chrome');

const driver = new webdriver.Builder()
  // The "9515" is the port opened by chrome driver.
  .usingServer('http://localhost:9515')
  .withCapabilities({
    chromeOptions: {
      args: ['--headless', '--disable-gpu', '--no-sandbox', '--disable-extensions', '--disable-dev-shm-usage', 'start-minimized'],
      // Here is the path to your Electron binary.
      binary: './dist_electron/mac/myapp.app/Contents/MacOS/myapp'
    }
  })
  .setChromeOptions(new chrome.Options().addArguments('--remote-debugging-port=7070'))
  .forBrowser('electron')
  .build()

driver.quit()

ps。我曾尝试使用ChromeDriver@74.x.x，但仍会导致相同的错误。

实际上，我尝试使用Selenium RobotFramework仍然发现相同的错误。我认为我的测试写作或某些设置有问题。（我的测试工具不好。）

仅供参考

mytest.robot

*** Settings ***
Library           Selenium2Library
Variables         vars.py

*** Test Cases ***
Foohaha
    Create Webdriver    Remote    desired_capabilities=${binary_location}    command_executor=http://localhost:9515
    Log To Console  ${item.get_attribute('innerHTML')}
    [Teardown]    Close All Browsers

P.s。之所以没有Spectron是我只使用硒的测试仪。

在尝试了几乎推荐的测试库之后。我结束了testcafe。将首选应用程序路径设置为我的分布式应用程序的二进制文件，然后将页面设置为以html文件形式在测试文件中打开。主路径是默认值。

这就是我的设置方式。

.testcafe-electron-rc

{
  "mainWindowUrl": "app://./index.html",
  "electronPath": "/Users/xxx/Documents/ProjectFolder/dist_electron/mac/my-lovely-app.app/Contents/MacOS/my-lovely-app",
  "openDevTools": "true"
}

package.json

"scripts": {
    ...
    "cafe": "testcafe \"electron:/Users/xxx/Documents/ProjectFolder/.testcafe-electron-rc\" \"/Users/xxx/Documents/ProjectFolder/tests/e2e/specs/testcafe.js\""
  },
"devDependencies": {
    ...
    "selenium-webdriver": "^4.0.0-alpha.1",
    "testcafe": "^1.1.4",
    "testcafe-browser-provider-electron": "0.0.8"
  }

testcafe.js

import { Selector } from 'testcafe';

fixture(`Index page`)
  .page('/Users/xxx/Documents/ProjectFolder/dist_electron/bundled/index.html');


test('Body > Paragraph contains "Hello World!"', async testController => {

  const paragraphSelector = await new Selector('#nav > a.router-link-exact-active.router-link-active');
  const txt = await new Selector('#app > div.auth-page > div > div > div > form > fieldset:nth-child(1) > input');

  await testController.click(paragraphSelector)
            .typeText(txt, 'Peter Parker');
            // .expect(paragraphSelector.innerText).eql("Login");//.eql('Login');
});

希望这会对某人有所帮助。
