If you run tests during the build, a run-time dependency often becomes a build-time dependency.

It is often also useful to distinguish between "build-time dependencies" and "build+test-time dependencies". In Debian we are (since a few years ago) able to distinguish the latter from the former, and it is possible to do a build without running the tests. However it then becomes impossible to run these build-time tests separately afterwards. So the official Debian build-farm infrastructure ignores this possibility of using a smaller set of "build dependencies without test dependencies".
