“无法在 60 秒内检索无人机实例”答案

【问题标题】："Unable to retrieve Drone Instance within 60 seconds"“无法在 60 秒内检索无人机实例”
【发布时间】：2018-01-01 21:44:36
【问题描述】：

我正在使用一本名为Workshop Java EE 7 的德国书学习Java EE 7，它基本上需要一个人手动构建一个正在运行的示例应用程序。在本书的第二个“迭代”中，定义了集成测试 (GitHub branch)。但是，我无法让它们运行。当我启动 WildFly 然后执行mvn verify 时，Firefox 打开时显示“没有可用的窗口”，60 秒后，它崩溃了，我得到一长串错误（见下文）。我一直在谷歌上搜索所有错误消息，尽管在各种平台（包括 StackOverflow）上讨论了许多类似的问题，但我找到的答案都没有解决我的问题。由于作者在网上提供了整个项目，我可以指出代码的相关部分：

我希望你能帮助我解决这个问题，特别是因为我确信它与本书的许多其他读者也相关，这本书是 amazon.de 上的顶级 Java EE 书籍之一。提前非常感谢您！

我正在使用 macOS 10.12、Java 8、WildFly 8.1.0 和 Firefox 57。

【问题讨论】：

问题表明浏览器没有响应。我在arquillian.xml 中看到webdriver 设置为firefox。试试htmlunit 或phantomjs，它们都是集成的无头浏览器。如果可行，那么问题不在 Arquillian 方面。
谢谢你，@BakusC。我之前确实尝试过phantomjs，也尝试过safari。这些尝试失败并出现类似的错误消息。当我今晚回家时，我也会发布它们。您是否尝试过运行该项目？它可以在你的机器上运行吗？
我还没有尝试过你的项目。我只是 Arquillian+Graphene 的长期用户（在 a.o. github.com/omnifaces/omnifaces 和 github.com/omnifaces/optimusfaces 中使用）
你能在 pom.xml 中尝试以下配置 maven-failsafe-plugin${version.failsafe.plugin}1true

标签： jakarta-ee selenium-webdriver jboss-arquillian arquillian-drone graphene2

【解决方案1】：

启动当前（或不受支持？）版本的 Firefox 可能需要很长时间。这至少是在 Linux 下按原样尝试项目时发生的情况（我手头没有 Mac）。通过添加增加超时时间

<extension qualifier="drone">
    <property name="instantiationTimeoutInSeconds">120</property>
</extension>

to arquillian.xml 使 TimeoutException 消失在我的设备上使用 Firefox 57。

不幸的是，测试现在以org.openqa.selenium.firefox.NotConnectedException: Unable to connect to host 127.0.0.1 on port 7057 after 45000 ms. 失败。 Firefox 中没有加载任何网页。 changelog 显示 Selenium 2.39 支持的最新 Firefox 版本似乎是 26.0。

显式使用此版本（通过arquillian.xml 的webdriver 配置中的<property name="firefox_binary">/path/to/firefox-26.0/firefox</property>）然后导致org.openqa.selenium.NoSuchElementException: Unable to locate element: {"method":"xpath","selector":"//button/span[text()='Aktion hinzufügen']"}，但这次显示了一个应用程序（英文，因为这是我的操作系统环境）。更改 AbstractPage#getString 以使用 English 资源包最终使测试变为绿色。因此，也许不要将您的选择器基于本地化的按钮标签...

有趣的是，使用 phantomjs 只适用于此处（但这次仅适用于德语 ResourceBundle）。

环境：

x86_64 上的 Ubuntu 17.10
Firefox 57（最初）和 26
Maven 3.5.0
OpenJDK 1.8.0_151（Ubuntu 存储库）
WildFly 8.1.0

【讨论】：

【解决方案2】：

我尝试在我的机器上运行 mvn verify，但它失败了，很可能是因为我机器上的 Firefox 版本对于那里的 Selenium 驱动程序来说太新了。

@Rene 在他的answer 中修复了这个问题，通过替换正确的 Firefox 版本，我决定升级 Arquillian 组件。所以这里是固定的代码：

Changes 让事情在 Firefox 57 上运行。
包含更改的test branch in my fork。
