Golang Performance Test

Format:

Func benchmarkxxx (b *testing. B

Simple code:

package examplesimport (    "io/ioutil"    "net/http"    "testing")// 测试并发效率func BenchmarkLoopsParallel(b *testing.B) {    b.RunParallel(func(pb *testing.PB) { //并发        for pb.Next() {            resp, err := http.Get("http://10.10.200.128:8080/image?t=MDA")            if err != nil {                // handle error            }            cookies := resp.Cookies()            verify_key := ""            for _, v := range cookies {                if v.Name == "VERIFY_KEY" {                    verify_key = v.Value                }            }            if err != nil {                // handle error            }            defer resp.Body.Close()            if verify_key == "" {                b.Fail()            }        }    })}

Run

Go test-bench= "."

• -parallel 50 Setting concurrency
• -count n Set Number of times

Testing. T

Failed to determine interface

• Fail to continue
• Failnow failed to terminate

Print Information interface

• Log data stream (cout similar)
• LOGF format (printf similar)
• Skipnow Skip Current Test
• Skiped detect if skipping

Integrated Interface Generation:

• Error/errorf report Error continue [Log/logf + Fail]
• Fatel/fatelf report Error terminated [Log/logf + Failnow]
• SKIP/SKIPF report and Skip [Log/logf + Skipnow]

Testing. B

First, testing. B owns testing. All interfaces of T.

• SetBytes (I UInt64) statistics memory consumption, if you need to.
• Setparallelism (p int) to develop a parallel number.
• Starttimer/stoptimer/reserttimer Operation Timer

Testing. PB

• Next () interface. Determine if the loop continues

Watch out.
