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: create_test.go
    path of file: ./repos/docker-ce/components/cli/cli/command/checkpoint
    
    the code of the file until where you have to start completion: package checkpoint

import (
	"io/ioutil"
	"strings"
	"testing"

	"github.com/docker/cli/internal/test"
	"github.com/docker/docker/api/types"
	"github.com/pkg/errors"
	"gotest.tools/v3/assert"
	is "gotest.tools/v3/assert/cmp"
)

func TestCheckpointCreateErrors(t *testing.T) {
	testCases := []struct {
		args                 []string
    
func TestCheckpointCreateErrors(t *testing.T) {
	testCases := []struct {
		args                 []string
		checkpointCreateFunc func(container string, options types.CheckpointCreateOptions) error
		expectedError        string
	}{
		{
			args:          []string{"too-few-arguments"},
			expectedError: "requires exactly 2 arguments",
		},
		{
			args:          []string{"too", "many", "arguments"},
			expectedError: "requires exactly 2 arguments",
		},
		{
			args: []string{"foo", "bar"},
			checkpointCreateFunc: func(container string, options types.CheckpointCreateOptions) error {
				return errors.Errorf("error creating checkpoint for container foo")
			},
			expectedError: "error creating checkpoint for container foo",
		},
	}

	for _, tc := range testCases {
		cli := test.NewFakeCli(&fakeClient{
			checkpointCreateFunc: tc.checkpointCreateFunc,
		})
		cmd := newCreateCommand(cli)
		cmd.SetArgs(tc.args)
		cmd.SetOut(ioutil.Discard)
		assert.ErrorContains(t, cmd.Execute(), tc.expectedError)
	}
