我该如何防止Go的Time.Format()函数去掉时间戳中小数部分末尾的零?以下是我编写的单元测试失败的代码。
有什么办法可以解决这个问题吗?
package main
import (
"testing"
"time"
)
func TestTimeFormatting(t *testing.T) {
timestamp := time.Date(2017, 1,2, 3, 4, 5, 600000*1000, time.UTC)
timestamp_string := timestamp.Format("2006-01-02T15:04:05.999-07:00")
expected := "2017-01-02T03:04:05.600+00:00"
if expected != timestamp_string {
t.Errorf("Invalid timestamp formating, expected %v, got %v", expected, timestamp_string)
}
}
输出:
$ go test
--- FAIL: TestTimeFormatting (0.00s)
main_test.go:14: Invalid timestamp formating, expected 2017-01-02T03:04:05.600+00:00, got 2017-01-02T03:04:05.6+00:00
