selenium standalone终止，出现未知错误

Question

当我开始我的测试时，浏览器打开并显示一个ip，几秒后，ip被更改为“data”；在终端中，测试被循环并发送err ms

empresss-Mac-mini:myApp admin$ protractor test/e2e.js在http://localhost:4444/wd/hub启动器上使用selenium服务器运行1个WebDriver实例启动Jasmine规范超时。重置WebDriver控制流。F

我的配置文件是

exports.config = {
  framework: 'jasmine2',
  seleniumAddress: 'http://localhost:4444/wd/hub',
  specs: ['../www/head.spec.js'],
  multiCapabilities: [
  {
    browserName: 'chrome'
  }],
  onPrepare: function(){
        browser.driver.get('http://192.168.1.2:8100');
    }
}

我把它命名为e2e.js，我的测试文件是

describe('header Module', function(){

   beforeEach(function() {
        var header = element(by.css('title'));
    });

   it('should check title text',function(){
        expect(header.getText()).toContain('Ionic Blank Starter');    
    });
});

我下载了一个空白ionic应用程序，我想测试标题包含元素"Ionic blank Starter“

您没有很好地处理项目中的异步代码。header.getText()返回一个promise，您需要在断言文本之前解析该promise。你可以这样做：

describe('header Module', function(){
it('should check title text',function(callback){
    var header = element(by.css('.title'));
    header.getText()
       .then(function (text) {
           expect(text).toContain('Ionic Blank Starter');
           callback();
       }); 
});
});
