// Evaluating scoring functions isn't a great fit for assert-based tests.
// For interesting cases, both exact scores and "X beats Y" are too brittle to
// make good hard assertions.
//
// Here we test the signal extraction and sanity-check that signals point in
// the right direction. This should be supplemented by quality metrics which
// we can compute from a corpus of queries and preferred rankings.
