推荐答案

错误说明了一切:

Build info: version: '2.48.2', revision: '41bccdd', time: '2015-10-09 19:59:12'
System info: host: 'xxx', ip: '192.168.43.34', os.name: 'Windows 8.1', os.arch: 'amd64', os.version: '6.3', java.version: '1.8.0_40'
Driver info: driver.version: FirefoxDriver

错误跟踪日志明确提到 Browser Client 无法识别回 FirefoxDriver 二进制文件.

The error trace logs clearly mention that Browser Client is unable to recognize back the FirefoxDriver binary.

您的主要问题是所使用的二进制文件之间的版本兼容性:

Your main issue is the version compatibility between the binaries you are using as follows :

  • 您的 Selenium Client 版本是 2015-10-09 19:59:12 的 2.48.2 ，几乎是 2.5岁.
  • 您的 JDK版本是 1.8.0_40 ，这很古老.
  • 您不知道您的 GeckoDriver 版本.
  • 您不知道您的 Firefox 版本.
  • Your Selenium Client version is 2.48.2 of 2015-10-09 19:59:12 which is almost 2.5 years older.
  • Your JDK version is 1.8.0_40 which is pretty ancient.
  • Your GeckoDriver version is unknown to us.
  • Your Firefox version is unknown to us.

因此 JDK v8u40 和 Selenium Client v2.48.2 之间存在明显的不匹配.

So there is a clear mismatch between the JDK v8u40 , Selenium Client v2.48.2.

  • 将 JDK 升级到最新级别 JDK 8u162 .
  • 将硒升级到当前级别> 版本3.11.0 > .
  • 将 GeckoDriver 升级到 GeckoDriver v0.20.0 级.
  • 将 Firefox 版本升级到 Firefox v59.0.1 级别.
    • 通过 IDE
  • 清理您的项目工作区和重建您的项目，并且仅具有必需的依赖项.
  • 使用 CCleaner 工具清除之前和之后的所有操作系统杂项在执行 test Suite 之后.
  • 如果您的基本 Firefox 基本版本太旧，请通过卸载它 Revo Uninstaller 并安装最新的GA和 Firefox 发行版本.
  • 执行您的@Test.
  • Upgrade JDK to recent levels JDK 8u162.
  • Upgrade Selenium to current levels Version 3.11.0.
  • Upgrade GeckoDriver to GeckoDriver v0.20.0 level.
  • Upgrade Firefox version to Firefox v59.0.1 levels.
  • Clean your Project Workspace through your IDE and Rebuild your project with required dependencies only.
  • Use CCleaner tool to wipe off all the OS chores before and after the execution of your test Suite.
  • If your base Firefox base version is too old, then uninstall it through Revo Uninstaller and install a recent GA and released version of Firefox.
  • Execute your @Test.
