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: limitedexecutor_test.go
    path of file: ./repos/go-zero/core/logx
    
    the code of the file until where you have to start completion: package logx

import (
	"sync/atomic"
	"testing"
	"time"

	"github.com/stretchr/testify/assert"
	"github.com/zeromicro/go-zero/core/timex"
)

func TestLimitedExecutor_logOrDiscard(t 
    
func TestLimitedExecutor_logOrDiscard(t *testing.T) {
	tests := []struct {
		name      string
		threshold time.Duration
		lastTime  time.Duration
		discarded uint32
		executed  bool
	}{
		{
			name:     "nil executor",
			executed: true,
		},
		{
			name:      "regular",
			threshold: time.Hour,
			lastTime:  timex.Now(),
			discarded: 10,
			executed:  false,

			name:      "slow",
			threshold: time.Duration(1),
			lastTime:  -1000,
			discarded: 10,

		},
	}

	for _, test := range tests {
		test := test
		t.Run(test.name, func(t *testing.T) {
			t.Parallel()

			executor := newLimitedExecutor(0)
			executor.threshold = test.threshold
			executor.discarded = test.discarded
