set variables before executing the "test-op"

Hi all,

I am using cl-project to generate project skeleton for the library
including separate asd file for unit tests.
The test framework I use is the default for cl-project: prove.
Using this framework I would like to set some special variables to control
test execution _before_ running the asdf:test-system
(setf prove.color:*enable-colors* nil)
(setf prove:*default-reporter* :tap)

But the problem is when I set them directly in .asd file, the CL reader
complains what the prove.color and prove packages do not exist (which is
true, since the prove dependency is not yet loaded).
I could set them in every test file, but I would like to set them globally.
How could I set them after the dependency to unit test library (prove) is
loaded and therefore package exists?

This is what I have in .asd file for tests:

:defsystem-depends-on (:prove-asdf)
:perform (test-op :after (op c)
(funcall (intern #.(string :run-test-system) :prove-asdf) c)
(asdf:clear-system c)))
