Is it impossible to use Guard with RubyMine?

For some inexplicable reason, RubyMine autosaves every change you make and so every key stroke will trigger Guard to run your tests! And the most ridiculous thing is that there's apparently no way to disable this autosaving "feature". I'm just wondering, RubyMine seems to be a very popular editor among Rails developers and Guard seems to be an indispensable tool used to automate testing. Since Guard is impossible to use reasonably with RubyMine, how do people deal with automating their tests with RubyMine?
