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: gocase_test.go
    path of file: ./repos/prisma-client-go/helpers/gocase
    
    the code of the file until where you have to start completion: package gocase_test

import (
	"fmt"
	"strings"
	"testing"
	"unicode/utf8"

	"github.com/steebchen/prisma-client-go/helpers/gocase"
)

func TestConverter_ToLower(t *testing.T) {
	t.Parallel()

	dc, _ := gocase.New()
	cc, _ := gocase.New(gocase.WithInitialisms("JSON", "CSV"))

	cases := []struct {
		conv       *gocase.Converter
		have, wan
    
func FuzzReverseLower(f *testing.F) {
	testcases := []string{"jsonFile", "ipAddress", "defaultDnsServer"}
	for _, tc := range testcases {
		f.Add(tc)
	}
	f.Fuzz(func(t *testing.T, orig string) {
		to := gocase.ToLower(orig)
		rev := gocase.Revert(to)
		if !ignoreInput(orig) && orig != rev {
			t.Errorf("before: %q, after: %q", orig, rev)
		}
		if utf8.ValidString(orig) && !utf8.ValidString(rev) {
			t.Errorf("To or Revert produced invalid UTF-8 string %q", rev)
		}
	})
}
