我正在尝试使用Capybara录制并以视频格式保存我的执行测试。我的测试通过了，但是我的Mac终端出现了几个错误。另外，视频也不会被记录/保存。

尝试替换这些行
page.save_screenshot('log/' + name + '-' + d.to_s + '.png')
headless.video.stop_and_save('log/' + name + '-' + d.to_s + '.mov')
使用
#please note for this ../ from this file to root just reach to root of the project. in my case root
root_path = File.join(File.dirname(__FILE__), "../")
page.save_screenshot(File.join(root_path,'log/' + name + '-' + d.to_s + '.png'))
headless.video.stop_and_save(File.join(root_path,'log/' + name + '-' + d.to_s + '.mov'))

我的搜索显示Mac与Xvfb不兼容，这是Headless所使用的。即使您通过了rails错误，也可能不会通过此错误。
