I feel there's too much nesting going on here. Also t.FailNow() wouldn't show the actual content of err. Finally, the original code was written before I realised I could do require.NoError(...) instead of assert.NoError(...) and it would immediately stop the test.

This would be better:

// Root can always create directories, so this test would fail with a
// confusing message. Instead it's better to refuse running as root at all.
currentUser, err := user.Current()
require.NoError(t, err)
require.NotEqual(t, "0", currentUser.Uid,
	"this test requires running as normal user, not %s (%s)", currentUser.Username, currentUser.Uid)
require.NotEqual(t, "root", currentUser.Username,
	"this test requires running as normal user, not %s (%s)", currentUser.Username, currentUser.Uid)
