How to get Spring to work with single file/line tests in Minitest

You can run single test using Rails 5 test runner by specifying the file and the line number like the following:

rails test path/to/test:55

Executing tests by using Rails 5 test runner has an advantage because it uses Spring preloader.

However, in RubyMine, you can run single test from context menu on a test you want to run. However, since it is not via the above test runner, it does not use Spring preloader and takes long to launch a test.

RubyMine documents say that Spring is used as a preloader by default, but as far as I see it is used only when you run whole tests instead of a single file and a single method. 

I have tried to create new Run/Debug configuration to run test via spring, but I am still not sure how to get it work.

Please let me know how to run single file/line test via Rail5 test runner or the way to get spring work along with single file/line test.
