fix minor unreachable code caused by t.Fatal

[Abirdcfly]

Type of change

• Test update

Description

t.Fatal or os.Exit will make the subsequent code unreachable.

https://pkg.go.dev/testing#T.Fatalf

Fatalf is equivalent to Logf followed by FailNow.

Additional details

see https://go.dev/play/p/I6MX-QOTC9n for t.Fatal example:

package main

import (
	"testing"
)

func TestLastIndex(t *testing.T) {
	t.Errorf("first line")
	t.Errorf("second line")
	t.Fatalf("t.Fatalf will cause exit")
	t.Fatalf("so this line cant reach")
}

/* output:
=== RUN   TestLastIndex
    prog.go:8: first line
    prog.go:9: second line
    prog.go:10: t.Fatalf will cause exit
--- FAIL: TestLastIndex (0.00s)
