Reason ： there is a problem of '060102150405' by time.parse, as the timeString is not have timezone, so it should be use time.ParseInLocation, if not, CleanupTestDatabase will delete db before 9 hours (if localzone is GMT+08:00)

func TestTemp(t *testing.T) {
    pastTime, _ := time.Parse("060102150405", "220112190045")
    fmt.Println(pastTime)
    now := time.Now()
    fmt.Println(now)
    subHour := time.Since(pastTime).Hours()
    fmt.Println(subHour)
    // output:
    //2022-01-12 19:00:45 +0000 UTC
    //2022-01-12 21:33:33.540297 +0800 CST m=+0.285287889
    //-5.453183249444445

    pastTime1, _ := time.ParseInLocation("060102150405", "220112190045", time.Local)
    fmt.Println(pastTime1)
    subHour1 := time.Since(pastTime1).Hours()
    fmt.Println(subHour1)
    // output:
    //2022-01-12 19:00:45 +0800 CST
    //2.5468167530555554
