Taurus(BZT)测试中ChromeDriver版本不匹配致会话创建失败求助

Chrome浏览器已升级至116.x版本，测试配置文件中明确指定使用ChromeDriver 116.0.5845.96并配置了对应下载链接，但测试运行时依然调用114版本的ChromeDriver，触发报错：

"session not created: This version of ChromeDriver only supports Chrome version 114"

日志显示已成功下载116版本的ChromeDriver，但实际执行时仍使用旧版本。

解决方案 #

1. 修复YAML配置格式与链接错误 #

原配置存在两个关键问题：

• download-link与chrome_version写在同一行，违反YAML语法，导致配置未被正确解析
• 下载链接指向Chrome浏览器压缩包（chrome-win64.zip），而非ChromeDriver安装包

修正后的配置：

modules:
  console:
    disable: true
  selenium:
    chromedriver:
      version: 116.0.5845.96
      download-link: https://edgedl.me.gvt1.com/edgedl/chrome/chrome-for-testing/116.0.5845.96/win64/chromedriver-win64.zip
      chrome_version: 116.0.5845.96

2. 清理Taurus缓存的旧驱动 #

Taurus会将驱动缓存到本地目录，默认路径：

• Windows：C:\Users\<你的用户名>\.bzt\selenium\chromedriver\
• Linux/macOS：~/.bzt/selenium/chromedriver/

进入该目录，删除114版本的chromedriver文件，仅保留116.0.5845.96版本文件。

3. 强制指定ChromeDriver本地路径 #

若缓存清理后仍不生效，可直接在配置中指定驱动本地路径，避免自动选择错误版本：

modules:
  console:
    disable: true
  selenium:
    chromedriver:
      path: "C:\\path\\to\\your\\chromedriver_116.exe"
      chrome_version: 116.0.5845.96

4. 检查系统PATH中的旧驱动 #

在命令行执行chromedriver --version，若显示114版本，说明系统PATH中存在旧驱动。移除该路径，或确保Taurus缓存的116版本路径优先级更高。
