Question

我正在尝试在CI中的docker中使用水豚和幻影运行rspec测试。我已经安装了google-chrome-stable，但收到疯狂的错误。

如果我只是运行我的rspec，它将启动puma来执行测试，然后再进行10分钟以上的操作。

疯狂的是，如果我添加rspec过滤器或排除模式，我的所有测试规范都会失败，并出现以下错误。

我正在使用最新版本的Rails 6.0.0rc2（rspec-rails，capybara，幽灵）

如果我在CI上运行测试而没有完整的测试，则一切正常。

我搜索了Could not load native IDN implementation.，并试图清除我的CI工作者的缓存，但这没有帮助。

我使用此docker文件构建映像

我只有5个测试示例，所以看起来失败的测试是来自内部的

有什么想法找出为什么我会遇到所有这些疯狂的错误吗？

Answer 1

为幻影驱动程序添加browser_options后修复的问题。如果没有--no-sandbox选项，Chrome将无法以root用户身份运行。要添加它，只需像这样初始化驱动程序

Capybara.register_driver :apparition do |app|
  opts = {
    headless: true,
    browser_options: [
      :no_sandbox,
      { disable_features: 'VizDisplayCompositor' },
      :disable_gpu
    ]
  }
  Capybara::Apparition::Driver.new(app, opts)
end

要求在带有CI的Docker中运行幻影？
