javascript - 在 Chrome 上运行 Node js Selenium 测试用例出现错误 Error : ECONNREFUSED connect ECONNREFUSED 127. 0.0.1:63528

Question

在 selenium Node js 上运行测试用例遇到错误错误:ECONNREFUSED 连接 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();
    });
});

我不确定您的示例是否有效，如果您想在本地运行测试，您需要安装并加载正确的 selenium 驱动程序。

对于 chrome，我尝试使用 var driver = new webdriver.Builder().forBrowser('chrome')语法运气不佳，chrome 会启动但不会运行测试，我刚刚看到你描述的错误。但是对于 FireFox var driver = new webdriver.Builder().forBrowser('firefox').build();完美运行!

我发现这个有效(在本地运行)

  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');
