Example
If you want to measure benchmarks add a testing method like this:
sum.go:
package sum
// Sum calculates the sum of two integers
func Sum(a, b int) int {
return a + b
}
sum_test.go:
package sum
import "testing"
func BenchmarkSum(b *testing.B) {
for i := 0; i < b.N; i++ {
_ = Sum(2, 3)
}
}
Then in order to run a simple benchmark:
$ go test -bench=.
BenchmarkSum-8 2000000000 0.49 ns/op
ok so/sum 1.027s
