If you use debhelper compat level 14, then the package will be built in a way that the actual build (compilation) happens during the dh_auto_build target, tests during dh_auto_test, and installation during dh_auto_install. Note however that debhelper-compat 14 is not really available from the debhelper side (i.e. it does not yet provide debhelper-compat (= 14)). To test this you have to build with DH_COMPAT=14 set.
