option

t.Setenv can use since Go1.17. This linter diagnostics, if Go version is since 1.17. But, if you wanna exec this linter in prior Go1.17, you can use it that you set -tenv.f flag.

e.g.

fish

go vet -vettool=(which tenv) -tenv.f sandbox_test.go

bash

go vet -vettool=`which tenv` -tenv.f main.go
