I found it, the answer is in the same testing Jamfile:

rule run ( sources + : args * : input-files * : requirements * :
target-name ? :  default-build * )
{
    target-name ?= $(sources[1]:D=:S=) ;
    v3_tests += [ testing.run $(sources) : $(args) : $(input-files) :
$(requirements) : $(target-name)-p3 : $(default-build) ] ;
}

Spirit overrides the rules defined by the normal testing framework. One of
the changes is that -p3 is added to any of the test names. Now that I know
this, it will be easier to finish the testing I was working on, thanks.
