无法通过 Jenkins 中的 Selenium Maven 使用 GeckoDriver Firefox 建立与 WindowServer 错误的默认连接

[英]FAILED TO establish the default connection to the WindowServer error using GeckoDriver Firefox through Selenium Maven in Jenkins

问题描述

所以我正在使用 java 和 maven 学习 selenium 和 jenkins 集成。 我在使用 chrome 和 jenkins 时遇到问题，并被告知我应该尝试使用 firefox webdriver。 所以这就是我所做的。 但是，当我在 jenkins 上运行构建时出现以下错误：谁能帮我解决这个问题？ 我的脚本在 IDE 本地运行良好。

我也在使用 mac 10.13.6 (High Sierra)、Firefox 70、Geckodriver v 0.26.0、3.141.59、Java eclipse ID 和 Maven 3.6.2

请帮助和感谢！

...暗示GeckoDriver无法启动/生成新的浏览上下文，即Firefox 浏览器会话。

您的主要问题是使用FirefoxDriver类的已弃用构造函数，如下所示：

在当前版本的Selenium v​​3.141.59 中，不推荐使用构造函数FirefoxDriver(Capabilities desiredCapabilities) 。

所需能力

解决方案

您需要使用MutableCapabilities Class 中的merge()方法将DesiredCapabilities类型对象合并到FirefoxOptions类型对象中，并通过传递FirefoxOptions对象来启动WebDriver和WebClient实例，如下所示：

@BeforeTest
public void startBrowser() {
    System.setProperty("webdriver.gecko.driver", driverPath);
    DesiredCapabilities capabilities = DesiredCapabilities.firefox();
    capabilities.setCapability("marionette", true);
    FirefoxOptions options = new FirefoxOptions();
    options.merge(capabilities);
    driver = new FirefoxDriver(options);
