I don't know of anything specific to 'application and system testing'. 
If I were you, I'd start with Test::Unit or its bigger brothers Shoulda 
or Rspec, and see if it does what you actually need.

You can call external programs using backticks, system() or IO.popen: 
e.g.

  def test_foo
    result = `foo`
    assert_equal 0, $?               # exit code
    assert_match /success/, result   # output on stdout
  end

You can call actual C using RubyInline or FFI.

You can do those actions using FileUtils. Or do you mean you want to be 
*notified* of those sorts of events happening in the filesystem? I'm not 
sure about that.

Not sure, I believe there is Win32 API (but I'm a Linux person).

I think Test::Unit has some graphical runners (but I'm a CLI person :-)
