Checking with Benchmarks, it seems there are no benchmarks tags. It is benchmark tests supported? Should I add something to the code to enable benchmarks?

import (
	. "gopkg.in/check.v1"
	"testing"

	_ "go.undefinedlabs.com/scopeagent/autoinstrument"
)

func Test(t *testing.T) { TestingT(t) } // Step 2

type TestSuite struct{} // Step 3

var _ = Suite(&TestSuite{}) // Step 4

func (s *TestSuite) BenchmarkLogic(c *C) {
	for i := 0; i < c.N; i++ {
		c.Assert("asd", Equals,"asd")
	}
}

Command:

$ go test -gocheck.b

You're right, Benchmark instrumentation is missing.... I don't know if it's better in a next PR, because this one is quite big already. What do you think? @drodriguezhdez

[drodriguezhdez]

Sure. Let's go for other PR for Benchmarks.
