Selenium始终出现“错误:超过2000ms超时" [英] Always getting 'Error: timeout of 2000ms exceeded' with Selenium

问题描述

早上好

我目前正在学习如何使用javascript(使用摩卡)来驱动Selenium.我创建了一个非常基本的测试，这给我在运行时带来了很多麻烦.每当我运行测试时，都会创建一个新的chrome实例，并显示浏览器.最初启动浏览器时，它将在URL框中放置"data:"，然后转到google.com.然后，我得到以下错误:

I am currently learning how to drive Selenium with javascript (using mocha). I created a really basic test that is giving me a lot of trouble at runtime. Whenever I run the test a new instance of chrome is created and the browser displays. When the browser initially comes up it places "data:," in the URL box then proceeds to google.com. I then get the following error back:

$摩卡咖啡测试

  Array
    #indexOf()
      ✓ should return -1 when the value is not present! 

  Google Search
    1) should work


  1 passing (2s)
  1 failing

  1) Google Search should work:
     Error: timeout of 2000ms exceeded
      at null.<anonymous> (/usr/local/lib/node_modules/mocha/lib/runnable.js:157:19)
      at Timer.listOnTimeout [as ontimeout] (timers.js:112:15)

这是测试本身:

var assert = require('assert'),
    test = require('selenium-webdriver/testing'),
    webdriver = require('selenium-webdriver'),
    chrome = require('selenium-webdriver/chrome');

test.describe('Google Search', function() {
  test.it('should work', function() {
    var chromeOptions = new chrome.Options();
    chromeOptions.addArguments(['test-type']);

    var driver = new webdriver.Builder().withCapabilities(chromeOptions.toCapabilities()).build();

    driver.get('http://www.google.com');
    driver.findElement(webdriver.By.name('q')).sendKeys('webdriver');
    driver.findElement(webdriver.By.name('btnG')).click();
    driver.wait(function() {
     return driver.getTitle().then(function(title) {  
       return title === 'webdriver - Google Search';
       });
    }, 1000);
    driver.quit();
  });
});

推荐答案

对我来说，您收到的错误消息看起来像是Mocha超时.在Mocha中设置超时的通常方法是:

The error message you get looks like a Mocha timeout to me. The normal way to set a timeout in Mocha is:

it("foo", function () {
    this.timeout(value);
    ...
});

其中，value是您想要的任何值(以毫秒为单位).值为0将关闭Mocha的超时.默认值为2000ms.

where value is whatever value you want (in ms). A value of 0 turns off Mocha's timeouts. The default is 2000ms.
