Tetrazolium testing is a method seed labs use to check viability without planting anything. A cut seed is soaked in a solution that stains living tissue red, so dead embryos stay pale and are easy to spot. It is mostly used by breeders and larger producers, and the quality notes at https://budweedseeds.com describe germination standards in general terms rather than listing such results. For a home grower, destroying seeds to test them rarely makes sense, but it explains how some batches get checked.
