Go Support

You can now use CodSpeed to benchmark Go codebases with the standard testing package and your existing go test workflow! No code changes required!

The integration is available in our codspeed-go repository.

Quick Start

CodSpeed works with your regular go test -bench runs. Write benchmarks with testing and CodSpeed will discover and run them.

Here is a simple example:

// fib_test.go
package example

import "testing"

func fib(n int) int {
  if n < 2 {
    return n
  }
  return fib(n-1) + fib(n-2)
}

func BenchmarkFibonacci10(b *testing.B) {
  // Preferred loop helper for precision
  for b.Loop() {
    fib(10)
  }
}

func BenchmarkFibonacci20(b *testing.B) {
  // Traditional pattern also supported
  for i := 0; i < b.N; i++ {
    fib(20)
  }
}
