SessionNotCreatedException：尝试通过 Java 使用 Selenium GeckoDriver 和 Firefox 运行命令而不建立连接错误

Question

我的浏览器在我的 selenium java 脚本中的随机位置崩溃。 有时它似乎也不会将文本放入输入框中。 发生这种情况时，有时我会看到一个壁虎驱动程序潜伏在任务管理器中，但并非每次都如此。

我已经捕获了壁虎跟踪日志。 无法转储浏览器，就像我尝试给它一个配置文件目录一样

壁虎驱动程序的参数：["-profile", "C:/Temp/FFProfiles/tmp"]

，它确实在其中创建了新的配置文件，但随后无法连接到浏览器（等待一分钟，然后抛出错误）

环境：

Java-1.8、Win-7、tomcat-8.0.30

尝试 Firefox 驱动程序 v-3.11.0.jar 到 3.141.59.jar

chrome 驱动程序 v-3.11.0.jar 到 3.141.59.jar，

selenium-server-standalone-3.11.0.jar 到 3.141.59.jar

尝试了无头和头..

以下是应用程序的堆栈跟踪：此时它在查找元素时崩溃了（即浏览器在之前的操作中崩溃了），其他时候在其他地方崩溃了..

这个错误信息...

org.openqa.selenium.SessionNotCreatedException: Tried to run command without establishing a connection
Build info: version: '3.11.0', revision: 'e59cfb3', time: '2018-03-11T20:33:15.31Z'
System info: host: 'PC-17', ip: '199.248.254.10', os.name: 'Windows 7', os.arch: 'amd64', os.version: '6.1', java.version: '1.8.0_65'

...暗示GeckoDriver无法启动/生成新的WebBrowsing 会话，即Firefox 浏览器会话。

您的主要问题是您使用的二进制文件版本之间的不兼容，如下所示：

• 您的JDK 版本是1.8.0_65 ，这是非常古老的。

因此JDK v8u65和Selenium Client v3.141.59之间存在明显的不匹配。

---

解决方案

• 将JDK升级到最新级别JDK 8u212 。
• 将Selenium升级到当前级别版本 3.141.59 。
• 升级GeckoDriver到GeckoDriver v0.24.0水平。
• GeckoDriver 存在于指定位置。
• GeckoDriver 对非 root 用户具有可执行权限。
• 将Firefox版本升级到Firefox v67.0级别。
