经过几个小时浏览互联网后，我无法找到解决方案。由于某些原因，我目前正在尝试在旧版本的 Firefox（此处为 v41.0）上测试我的应用程序。我正在传递集线器（v3.4.0）的 Selenium docker图像和 Firefox节点（v41.0）的 docker 图像。

我知道对于旧版本的 Firefox，Geckodriver 不兼容，但似乎有一个解决方案使用

{ "marionette": true }

Firefox 节点完美连接到网格。我可以使用它连接到它，docker exec -it <container-id> bash但是在运行测试时会出现问题。

我仍在尝试找到它，但我被阻止了。这里是 Dockerfile 的代码：hub.docker.com/r/selenium/node-firefox/~/dockerfile/ 用于 Firefox 节点，这里是测试代码（使用 MochaJS）。

test.it("should redirect to Google with FIREFOX 41.0", () => {

    var firefoxCap = Capabilities.firefox();
    firefoxCap.set('marionette', true);

    driver = new webdriver.Builder()
        .usingServer(CONSTANTS.SELENIUM_HUB)
        .withCapabilities(firefoxCap)
        .build();

    driver.get(CONSTANTS.GOOGLE_URL);
    driver.wait(until.titleIs(CONSTANTS.GOOGLE_TITLE));
    driver.wait(until.elementLocated(By.name(CONSTANTS.GOOGLE_SEARCH_KEY))).sendKeys(CONSTANTS.GOOGLE_SEARCH_VALUE);
    driver.findElement(By.name(CONSTANTS.GOOGLE_SEARCH_BUTTON_NAME)).click();
    driver.wait(until.titleIs(CONSTANTS.GOOGLE_SEARCH_TITLE));
    driver.wait(until.elementLocated(By.tagName(CONSTANTS.GOOGLE_RES_LINK))).click();
    driver.wait(until.titleIs(CONSTANTS.GOOGLE_TITLE));
    driver.quit();
});

这里的日志

Closing the tests

当因为“谷歌是你的朋友”而搜索问题时，唯一的回应是“更新你的 Firefox 版本”或“降级你的 Selenium 版本”，但我不能。有人可以解释我如何使它工作吗？甚至可以接受一种解决方法。

谢谢

当您使用时Selenium 3.4.0，Mozilla Firefox 41.0您需要将您geckodriver的版本降级为v0.17.0或v0.16.1或v0.16.0.

以下是最后宣布的依赖项：

geckodriver v0.18.0现在推荐Firefox 53 and greater

geckodriver v0.16.0只兼容Selenium 3.4 and greater

最后，假设geckodriver.exe绝对路径在您的范围内，您System/User Path必须将marionette属性显式设置为false（强制）

您的代码块将如下所示：

test.it("should redirect to Google with FIREFOX 41.0", () => {

    var firefoxCap = Capabilities.firefox();
    firefoxCap.set('marionette', false);

    driver = new webdriver.Builder()
        .usingServer(CONSTANTS.SELENIUM_HUB)
        .withCapabilities(firefoxCap)
    .build();

用于打开旧版 Mozilla Firefox 47.0.1 (geckodriver v0.16.1) 的 Java 代码：

import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.openqa.selenium.remote.DesiredCapabilities;

public class Opening_FIREFOX_legacy 
{
    public static void main(String[] args) 
    {
        System.setProperty("webdriver.gecko.driver", "C:\\Utility\\BrowserDrivers\\geckodriver-v0.16.1-win64\\geckodriver.exe");
        DesiredCapabilities dc = DesiredCapabilities.firefox();
        dc.setCapability("firefox_binary", "C:\\Program Files\\Mozilla Firefox47\\firefox.exe");
        dc.setCapability("marionette", false);
        WebDriver driver =  new FirefoxDriver(dc);
        driver.manage().window().maximize();
        driver.get("https://google.com");
    }
}

用于打开旧版 Mozilla Firefox 47.0.1 (geckodriver v0.18.0) 的 Python 代码：

from selenium import webdriver
from selenium.webdriver.firefox.firefox_binary import FirefoxBinary
from selenium.webdriver.common.desired_capabilities import DesiredCapabilities

binary = FirefoxBinary(r'C:\Program Files\Mozilla Firefox47\firefox.exe')
caps = DesiredCapabilities().FIREFOX
caps["marionette"] = False
driver = webdriver.Firefox(capabilities=caps, firefox_binary=binary, executable_path="C:\\Utility\\BrowserDrivers\\geckodriver.exe")
driver.get('https://stackoverflow.com')
