算法之神Donald Knuth说过：过早优化是万恶之源。Go语言的哲学是：Less is more。根据Go语言哲学我们可以推导出以下推论：
- Slow is fast：代码写的慢一点，代码执行可以变得快一点
- Slow is fast：如果程序跑的慢一点，代码可以写的快一点
- Fast is slow：代码写的很快，那么运行就很容易变慢，同时会拖累项目开发进度变慢
- Fast is slow：如果程序跑的快，写代码就很容易变慢
- 百米赛跑的冠军注定赢不了马拉松的冠军
因此，在满足要求的前提下，我更喜欢符合Go语言哲学的方案。

## 辅助函数
为了便于测试，构造了`Assert`和`Assertf`函数：
```go
func Assert(tb testing.TB, condition bool, a ...interface{}) {
tb.Helper()
if !condition {
if msg := fmt.Sprint(a...); msg != "" {
tb.Fatal("Assert failed: " + msg)
} else {
tb.Fatal("Assert failed")
}
}
}
func Assertf(tb testing.TB, condition bool, format string, a ...interface{}) {
tb.Helper()
if !condition {
if msg := fmt.Sprintf(format, a...); msg != "" {
tb.Fatal("Assert failed: " + msg)
} else {
tb.Fatal("Assert failed")
}
}
}
```
在单元测试中可以这样使用：
```go
func TestFoo(*testing.T) {
Assert(t, 1+1 == 2, "some", "message")
}
func TestBar(*testing.T) {
Assertf(t, 1+1 == 2, "%s, %s", "some", "message")
}
```
也可以在基准测试中使用：
```go
func BenchmarkHello(b *testing.B) {
for i := 0; i < b.N; i++ {
v := fmt.Sprintf("hello")
Assert(b, v == "hello")
}
}
```
