java - SessionNotCreatedException：试图通过 Java 使用 Selenium GeckoDriver 和 Firefox 运行命令而不建立连接错误
问题描述
我的浏览器在我的 selenium java 脚本中的随机位置崩溃。有时它似乎也没有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。无法获取浏览器的转储，就像我尝试为其提供配置文件目录时一样
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（等待一分钟然后引发错误）
环境：
Java-1.8、Win-7、tomcat-8.0.30
试过firefox驱动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
试过无头和头..
以下是来自应用程序的堆栈跟踪：此时它在查找元素时中断（即浏览器在之前的操作中崩溃），其他时候在其他地方崩溃..

...暗示GeckoDriver无法启动/产生新的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非常古老。
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。
- 将GeckoDriver升级到GeckoDriver v0.24.0级别。
- 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。
