Question

我创建了多个使用chromedriver在Chrome中运行测试的JavaScript测试，现在我想在FireFox和IE中运行相同的测试。这是我的一项测试，它在Chrome中正常运行，没有任何问题：

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


test.describe('Click current location button.', function () {
    test.it('Seems to have worked.', function () {
        var driver = new webdriver.Builder().
        withCapabilities(webdriver.Capabilities.chrome()).
        build();
        // Open Chrome (as specified by the Capabilities above) and go to the specified web page
        driver.get('website url').

        then(function () {

            driver.wait(function () {
                console.log("Looking for username");
                return driver.findElement(webdriver.By.id('user_username')).isDisplayed();
            }, 5000, 'Page did not load within 5 seconds');

            driver.findElement(webdriver.By.id("user_username")).sendKeys('user');
            driver.findElement(webdriver.By.id("user_password")).sendKeys('pword');

            return driver.findElement(webdriver.By.id("signIn")).click();
        }).
        then(function () {

            driver.sleep(4000);

            // make sure page has loaded        
            driver.wait(function () {
                console.log("Looking for current button");
                return driver.findElement(webdriver.By.id('gaz_input')).isDisplayed();
            }, 5000, 'Page did not load within 5 seconds');

            // Click Accept cookies to prevent issues 
            if (driver.findElement(webdriver.By.xpath("//a[@class='cc-cookie-accept']")).isDisplayed()) {
                driver.findElement(webdriver.By.xpath("//a[@class='cc-cookie-accept']")).click();
            }
            driver.sleep(1000);

            // Click the current location button
            driver.findElement(webdriver.By.xpath("//button[@class='btn']")).click();

            console.log("Looking for search results");
            driver.manage().timeouts().implicitlyWait(60000);

            if (!driver.findElement(webdriver.By.xpath("//div[@class='panel panel-default']")).isDisplayed()) {
                driver.wait(function () {                   
                    return driver.findElement(webdriver.By.xpath("//div[@class='panel panel-default']")).isDisplayed();
                }, 2000, 'Query did not complete within 60 seconds.');
            }

            driver.sleep(1000);
        }).
        then(function () {
            // Close the browser
            return driver.quit();
        });
    });
});

所以现在我想在FF和IE中运行这个测试。我认为使用FF，我所要做的就是改变功能，它应该可以工作，但这并没有发生。对于IE我认为我只需要下载IEDriverServer并将其放在与chromedriver相同的文件夹中，但是当我这样做并将驱动程序功能从chrome更改为internetexplorer时测试对它也不起作用。

如果我在功能设置为internetexplorer时尝试运行测试，则会出现此错误：

C:\Projects\build>mocha ietest.js

1) Click current location button. Seems to have worked.:

    }

如果我将功能更改为firefox，我会收到此错误：

我一直在争论这个问题很长一段时间没有任何成功，任何帮助真的很值得赞赏。它可能只是一些小的东西，我没有正确地做，但我还没有能够弄明白。

感谢，安东尼

对于Firefox，请参阅https://code.google.com/p/selenium/wiki/WebDriverJs#Using_the_Stand-alone_Selenium_Server中WebDriverJs文档中的代码示例。您需要安装独立的Selenium Server，并在代码示例中使用适当的值填写pathToSeleniumJar。

对于IE，你可以做类似的事情：

var webdriver = require('selenium-webdriver'),
    SeleniumServer = require('selenium-webdriver/remote').SeleniumServer;

var pathToSeleniumJar = 'C:\\selenium-2.41.0\\selenium-server-standalone-2.41.0.jar';

var server = new SeleniumServer(pathToSeleniumJar, {
  port: 4444
});

server.start();

var driver = new webdriver.Builder().
    usingServer(server.address()).
    withCapabilities(webdriver.Capabilities.ie()).
    build();

这应该可以正常工作，因为IE驱动程序应该已经在您的路径中。另请参阅https://code.google.com/p/selenium/wiki/InternetExplorerDriver以了解您可能需要对IE设置进行的调整。

Answer 2

我知道自问这个问题已经有一段时间了，但对于遇到这个问题的任何人来说，这可能有所帮助。

看起来Selenium Server还没有为您启动。我等待Server执行代码之前启动服务器。

function startSeleniumServer(callback) {

   seleniumServer = new SeleniumServer(path/to/selenium/server/jar, { port: 4444 });
   var promise = seleniumServer.start();
   promise.then(function() {
      console.log("Selenium Server: Started");
      return callback();
   });
};

使用Selenium WebdriverJS与FireFox和IE的问题
