Question

这个错误是什么意思？我似乎无法在此处找到任何其他内容...我在根chromedriver文件夹中有selenium-server-standalone和bin。提前致谢

Starting selenium server... started - PID:  33239

Error retrieving a new session from the selenium server

Connection refused! Is selenium server started?
{ value:
   { message: 'Cannot define class using reflection',
     error: 'unknown error' },
  status: 13 }

sample_tests.js （配置时占位符测试）

module.exports = {
  'Google Header'(client) {
    client
      .url('http://www.google.com')
      .waitForElementVisible('.header h1')
      .expect.element('.main').to.not.be.present;
    client.end();
  }
}

Answer 1

当我刷新我的机器并最终安装Java 10时，我遇到了这个问题。我们团队的其余成员仍然使用Java 9，它对他们来说很好。我没有降级到Java 9，而是从selenium-server-standalone-3.8.1更新到selenium-server-standalone-3.12.0和chromedriver2.38 - ＆gt; chromedriver2.40。

希望同样的事情对你有用。
