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: pr211_2_test.go
    path of file: ./repos/mergo
    
    the code of the file until where you have to start completion: package mergo

import (
	"reflect"
	"testing"
	"time"
)

type tra
    
func Test_deepMergeTransformerInvalidDestination(t *testing.T) {
	foo := time.Time{}
	src := reflect.ValueOf(foo)
	deepMerge(reflect.Value{}, src, make(map[uintptr]*visit), 0, &Config{
		Transformers: &transformer{},
	})
	// this test is intentionally not asserting on anything, it's sole
	// purpose to verify deepMerge doesn't panic when a transformer is
	// passed and the destination is invalid.
}
