Question

我已完成本教程http://www.protractortest.org/#/tutorial的所有内容和
https://github.com/angular/protractor-cookbook/tree/master/protractor-docker

（我最近从隔离的硒中心和节点更改为https://hub.docker.com/r/selenium/standalone-chrome/）

我创建了一个protractor.config.js：

exports.config = { 
  framework: 'jasmine', 
  seleniumAddress: 'http://localhost:4455/wd/hub', 
  specs: ['../tests/protractor/spec.js'], 
}

我在test / protractor / spec.js中的测试

// spec.js
describe('Protractor Demo App', function() {
  it('should add one and two', function() {
    browser.get('http://juliemr.github.io/protractor-demo/');
    element(by.model('first')).sendKeys(1);
    element(by.model('second')).sendKeys(2);

    element(by.id('gobutton')).click();

    expect(element(by.binding('latest')).getText()).
        toEqual('5'); // This is wrong!
  });
});

这些是我的硒中心和铬节点：

docker run -d -p 4455:4444 --name selenium-hub selenium/hub:latest
docker run -d --link selenium-hub:hub selenium/node-chrome:latest

给出了这些docker容器：

806106331d22        selenium/node-chrome:latest   "/opt/bin/entry_point"   23 seconds ago      Up 22 seconds                                        insane_newton
d93265006f9d        selenium/hub:latest           "/opt/bin/entry_point"   37 minutes ago      Up 37 minutes              0.0.0.0:4455->4444/tcp    selenium-hub

这是最新发生的事情：

./node_modules/.bin/protractor tests/config/protractor.conf.js
[16:01:28] I/launcher - Running 1 instances of WebDriver 
[16:01:28] I/hosted - Using the selenium server at http://localhost:4455/wd/hub

一分钟后我得到这个错误：

可能是什么原因？

Answer 1

请在conf文件和spec文件中添加以下内容，然后运行

   browser.ignoreSynchronization=true;

并在使用URL

启动浏览器后添加等待时间

   browser.sleep(5000);

并在Conf文件中使用Jasmine默认超时间隔和功能

显式添加

   browserName:"chrome"

请确保Conf和Spec文件位于同一位置。

Answer 2

exports.config = {                                                                   
  capabilities: {                                                       
    'browserName': 'chrome'                                             
  },                                                                           
  framework: 'jasmine',                                                                                              
  seleniumAddress: 'http://localhost:4455/wd/hub', 
  specs: ['../tests/protractor/spec.js'],                                                                       
  jasmineNodeOpts: {                                                    
    defaultTimeoutInterval: 30000                                       
  }                                                                     
};

量角器+ Selenium Chrome Docker = WebDriverError：未知错误：Chrome无法启动：正常退出
