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: generator_test.go
    path of file: ./repos/flyte/flytestdlib/cli/pflags/api
    
    the code of the file until where you have to start completion: package api

import (
	"context"
	"flag"
	"go/token"
	"go/types"
	"io/ioutil"
	"os"
	"path/filepath"
	"reflect"
	"strings"
	"testing"

	"github.com/stretchr/testify/assert"
)

// Make sure existing config file(s) parse correctly before overriding them with this flag!
var update = flag.Bool("update", false, "Updates testdata")

// If v is a pointer, it will get its element value or the zero value of the element type.
// If v is not a pointer, it will return it as is.
func elemValueOrNil(v inter
    
func TestDiscoverFieldsRecursive(t *testing.T) {
	t.Run("empty struct", func(t *testing.T) {
		ctx := context.Background()
		defaultValueAccessor := "defaultAccessor"
		fieldPath := "field.Path"
		pkg := types.NewPackage("p", "p")
		n1 := types.NewTypeName(token.NoPos, pkg, "T1", nil)
		namedTypes := types.NewNamed(n1, new(types.Struct), nil)
		//namedTypes := types.NewNamed(n1, nil, nil)
		fields, _, err := discoverFieldsRecursive(ctx, "p", namedTypes, defaultValueAccessor, fieldPath, false)
		assert.Nil(t, err)
		assert.Equal(t, len(fields), 0)
	})
}
