That sounds fine to me, but the issue was your comment that 'it is not straightforward' to compensate for time people spend on tests (good or bad tests; yours sound the good kind, kudos to you); if it is not straightforward then maybe find another way of doing it without them. But for sure, it's not simple and definitely things that are close to what the job is would be kind of perfect; I would imagine, also kind of hard to come with.
