我想我以前也遇到过这个问题。

当你用Ruby编写selenium脚本时，你可以控制浏览器的所有窗口。但是文件选择器对话框和文件下载对话框实际上是系统窗口，因此您无法通过 selenium 控制它们。

但是，您可以通过 Win32OLE gem 控制它们，以便在 Windows 上运行测试。但当然，您无法在 Mac 或 Linux 上运行这些测试。

就像一般的硒一样，它有点hacky。但它的工作原理如下：

 require 'selenium'
 require 'test/unit'
 require 'win32ole'

 class DownloadFileTest < Test::Unit::TestCase
   def setup()
     @wsh = WIN32OLE.new('Wscript.Shell')
   end
   def teardown
     WIN32OLE.ole_free(@wsh) # yes, this is required *rolls eyes*
   end
   def test_download_file
     # ...stuff that causes a download window to pop up...
     @wsh.AppActivate("Opening")
     sleep(2)
     @wsh.SendKeys("{RIGHT}{ENTER}") # Hits ok button - file downloads
     sleep(3)
     # Use regular Ruby File methods to assert stuff on the file content
   end

I think I've run into this problem before.

When you write selenium scripts in Ruby, you can control all the windows of the browser. But the file chooser dialog, and the file download dialog, are actually system windows, so you can't control them via selenium.

You can, however, control them via the Win32OLE gem, for tests running on Windows. But of course then you can't run those tests on Macs or Linux.

Like selenium in general, it's kind of hacky. But here's how it works:

 require 'selenium'
 require 'test/unit'
 require 'win32ole'

 class DownloadFileTest < Test::Unit::TestCase
   def setup()
     @wsh = WIN32OLE.new('Wscript.Shell')
   end
   def teardown
     WIN32OLE.ole_free(@wsh) # yes, this is required *rolls eyes*
   end
   def test_download_file
     # ...stuff that causes a download window to pop up...
     @wsh.AppActivate("Opening")
     sleep(2)
     @wsh.SendKeys("{RIGHT}{ENTER}") # Hits ok button - file downloads
     sleep(3)
     # Use regular Ruby File methods to assert stuff on the file content
   end
