[racket] DrRacket submodules to run

If I look at the language setting details I can choose what submodules to run (main / test / others). But what I can't control is the _order_ of the submodules. I simply don't want to run main if my tests are going to fail but for some reason tests run afterwards, not before. My questions:

1) Is there a reason for running main and then test, not the other way around? Cause I simply don't get it.

2) Is there any way for me to override this order?

3) If #2 is possible, is there a way to ensure that main won't run if test fails?
