Question

我正在使用一本名为Workshop Java EE 7的德语书籍学习Java EE 7，这本书基本上可以用来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，正在定义集成测试（GitHub branch）。但是，我不能让它们运行。当我启动WildFly然后执行mvn verify时，Firefox会打开“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）。我一直在谷歌搜索所有错误消息，即使在各种平台（包括StackOverflow）上讨论了许多类似的问题，我找到的答案都没有解决我的问题。由于作者在线提供了整个项目，我可以向您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也与本书的许多其他读者有关，这本书是关于amazon.de的顶级Java EE书籍之一。非常感谢你！

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

在下面找到错误消息的缩短控制台输出：

<some other test cases left out for brevity>

Answer 1

启动当前（或不受支持的？）版本的Firefox可能只需要太长时间。这至少是在Linux下按原样尝试项目时发生的事情（我手头没有Mac）。通过添加

来增加超时

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

arquillian.xml使用Firefox 57使我的设备上的TimeoutException消失。

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

在<property name="firefox_binary">/path/to/firefox-26.0/firefox</property>中的网络驱动程序配置中明确使用此版本（通过arquillian.xml），然后转到org.openqa.selenium.NoSuchElementException: Unable to locate element: {"method":"xpath","selector":"//button/span[text()='Aktion hinzufügen']"}，但这次会显示一个应用程序（ English 因为这是我的操作系统设置）。更改AbstractPage#getString以使用英语资源包最终会使测试变为绿色。因此，也许不要将选择器基于本地化按钮标签......

有趣的是，使用phantomjs只能在这里工作（但这次只能使用德语 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 repo）
WildFly 8.1.0

Answer 2

我试图运行mvn verify并且在我的机器上失败了，很可能是因为我的机器上的firefox版本对于那里的Selenium驱动程序来说太新了。

@Rene在他的answer修复中，通过替换正确的Firefox版本，我决定升级Arquillian组件。所以这是固定代码：

Changes使用Firefox 57运行。
