package ce import ( "crypto/md5" "math/rand" ) func getmd5(s []byte) []byte { md := md5.New() md.Write(s) x := md.Sum([]byte("")) return x } func T() string { name := rangdom_string() x := getmd5(name) if x[0] > 127 { return "A" } else { return "B" } } func rangdom_string() []byte { var x []byte for i := 0; i < 10; i++ { a := rand.Intn(100) x = append(x, byte(a+33)) } return x }
测试文件必须是*_test.go结尾
package ce import "testing" func Test_getmd5(t *testing.T) { for i := 0; i < 1000000; i++ { T() } } func Benchmark_getmd5(b *testing.B) { for i := 0; i < b.N; i++ { T() } } func Test_Range(t *testing.T) { for i := 0; i < 1000000; i++ { rangdom_string() } }
