This makes easier to read and debug these tests. This also reduces test lines count by 15% from 3K to 2.5K See https://itnext.io/f-tests-as-a-replacement-for-table-driven-tests-in-go-8814a8b19e9e While at it, consistently use t.Fatal* instead of t.Error*, since t.Error* usually leads to more complicated and fragile tests, while it doesn't bring any practical benefits over t.Fatal*.
