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: initialism_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

import (
	"testing"
)

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

	cases := []struct {
		in      []string
		want    []initialism
		wantErr string
	}{
		{in: []string{"ACL"}, want: []initialism{newInitialism("ACL", "Acl")}},
		{in: []string{"api", "aSCII"}, want: []initialism{newInitialism("API", "Api"), newInitialism("ASCII", "Ascii")}},
		{in: []string{"UTF!"}, wantErr: "input \"UTF!\" is not alpha-numeric character"},
	}

	for _, c := range cases {
		r, err := createInitialisms(c.in...)
		if c.wantErr == "" {
			switch {
			case err != nil:
				t.Errorf("error must not be occurred: %v", err)
			case len(r) != len(c.want):
				t.Errorf("value length doesn't match: %d (want %d)", len(r), len(c.want))
			default:
				for i, w := range c.want {
					if r[i] != w {
						t.Errorf("value doesn't match: %v (want %v)", r[i], w)
					}
				}
			}
		} else {
			if err == nil {
    
func TestCreateInitialisms(t *testing.T) {
	t.Parallel()

	cases := []struct {
