javascript - 在 FireFox 和 IE 中使用 Selenium WebdriverJS 时出现问题

Question

我创建了多个 JavaScript 测试，这些测试使用 chromedriver 在 Chrome 中运行测试，现在我想在 FireFox 和 IE 中运行相同的测试。 这是我的测试之一，它在 Chrome 中正常工作，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。我认为对于 FF，我所要做的就是改变功能，它应该就能正常工作，但那没有发生。 对于 IE，我以为我只需下载 IEDriverServer 并将其放在与 chromedriver 相同的文件夹中，但当我这样做并将驱动程序功能从 chrome 更改为 internetexplorer 时 测试也不起作用。

如果我在功能设置为 internetexplorer 时尝试运行测试，则会收到此错误:

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

    if (opt_other) {
        this.merge(opt_other);
    }
} has no method 'internetexplorer'

如果我更改 Firefox 的功能，我会收到此错误:

我已经解决这个问题很长时间了，但没有取得任何成功，任何帮助真的将不胜感激。这可能只是一些小事，我做得不正确，但我一直无法弄清楚。

谢谢， 安东尼

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

对于 IE，您可以执行类似的操作:

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您可能需要对 IE 设置进行调整。
