I am used to slightly abusing compile command to run unittests, because i
get the nice go to file:line behavior on failures.  But I am now unittesting
3 different files at different levels of abstraction and constantly
going back and forth between the tests.  When I am unittesting a single file
at a time, compile-command works beautifully.  But now I need to constantly
re-type the compile command when I want to change the test I am running.

Is there a way to add history to the compile command function?
 Alternatively, can I augment use some shell mode (which obviously has
command history) with the go to file:line behavior when I get a test
failure?
