You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: hystrix_test.go
    path of file: ./repos/kit/circuitbreaker
    
    the code of the file until where you have to start completion: package circuitbreaker_test

import (
	"io/ioutil"
	stdlog "log"
	"testing"
	"time"

	"github.com/afex/hystrix-go/hystrix"

	"github.com/go-kit/kit/circuitbreaker"
)

func TestHystrix(t *testing.T) {
	stdlog.SetOutput(ioutil.Discard)

	const (
		commandName   = "my-endpoint"
		errorPercent  = 5
		ma
    
func TestHystrix(t *testing.T) {
	stdlog.SetOutput(ioutil.Discard)

	const (
		commandName   = "my-endpoint"
		errorPercent  = 5
		maxConcurrent = 1000
	)
	hystrix.ConfigureCommand(commandName, hystrix.CommandConfig{
		ErrorPercentThreshold: errorPercent,
		MaxConcurrentRequests: maxConcurrent,
	})

	var (
		breaker          = circuitbreaker.Hystrix(commandName)
		primeWith        = hystrix.DefaultVolumeThreshold * 2
		shouldPass       = func(n int) bool { return (float64(n) / float64(primeWith+n)) <= (float64(errorPercent-1) / 100.0) }
		openCircuitError = hystrix.ErrCircuitOpen.Error()
	)

	// hystrix-go uses buffered channels to receive reports on request success/failure,
	// and so is basically impossible to test deterministically. We have to make sure
	// the report buffer is emptied, by injecting a sleep between each invocation.
	requestDelay := 5 * time.Millisecond

	testFailingEndpoint(t, breaker, primeWith, shouldPass, requestDelay, openCircuitError)
