在Chrome上运行节点js selenium测试用例获取错误错误：ECONNREFUSED连接ECONNREFUSED 127.0.0.1:63528

问题描述

在selenium node js上运行测试用例得到错误错误：ECONNREFUSED连接ECONNREFUSED。

Running a test case on selenium node js got error Error: ECONNREFUSED connect ECONNREFUSED.

测试用例

var assert = require('assert'),
    test = require('selenium-webdriver/testing'),
    webdriver = require('selenium-webdriver');
test.describe('Google Search', function () {
    test.it('should work', function (done) {
        this.timeout(100000);
        var driver = new webdriver.Builder().withCapabilities(webdriver.Capabilities.chrome()).build();
        driver.get('http://www.google.com');
        var searchBox = driver.findElement(webdriver.By.name('q'));
        searchBox.sendKeys('simple programmer');
        searchBox.getAttribute('value').then(function (value) {
            assert.equal(value, 'simple programmer');
        });
        driver.quit();
        done();
    });
});

错误堆栈跟踪如下

推荐答案

我我不确定你的例子是否可行，如果你想在本地运行测试，你需要安装和加载正确的selenium驱动程序。

I'm not sure your example would work, if you want to run the tests locally you would need to install and load the correct selenium drivers.

对于chrome我尝试使用 var驱动程序=新的webdriver.Builder（）。forBrowser（'chrome'）语法没有运气，chrome会启动但不会运行测试，我刚看到错误你描述。
但是对于FireFox var driver = new webdriver.Builder（）。forBrowser（'firefox'）。build（）; 完美运行！

For chrome I tried to use the var driver = new webdriver.Builder().forBrowser('chrome') syntax with no luck, chrome would fire up but not run tests, I just saw the error you describe.However for FireFox var driver = new webdriver.Builder().forBrowser('firefox').build(); workes perfectly !

我发现这有效（在本地运行）

I found this works (running locally)

  var assert = require('assert'),
    webdriver = require('selenium-webdriver'),
    By = webdriver.By,
    until = webdriver.until,
    chrome = require('selenium-webdriver/chrome'),
    firefox = require('selenium-webdriver/firefox');

  var path = require('chromedriver').path;
  var driver = chrome.Driver.createSession(new chrome.Options(), new
  chrome.ServiceBuilder(path).build());

  driver.get('http://mysite/myapp/tests/functional/start.html');

  //tests here
