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: query_executor_internal_test.go
    path of file: ./repos/goqu/exec
    
    the code of the file until where you have to start completion: package exec

import (
	"context"
	"database/sql"
	"encoding/json"
	"fmt"
	"strings"
	"testing"
	"time"

	"github.com/DATA-DOG/go-sqlmock"
	"github.com/stretchr/testify/suite"
)

var 
    
func (qes *queryExecutorSuite) TestScanStructsContext_badValue() {
	type StructWithTags struct {
		Address string `db:"address"`
		Name    string `db:"name"`
	}

	tests := []struct {
		name  string
		items interface{}
	}{
		{
			name:  "non-pointer items",
			items: []StructWithTags{},
		},
		{
			name:  "non-slice items",
			items: &StructWithTags{},
		},
	}
	for i := range tests {
		test := tests[i]
		qes.Run(test.name, func() {
			db, mock, err := sqlmock.New()
			qes.NoError(err)
			mock.ExpectQuery(`SELECT \* FROM "items"`).
				WithArgs().
				WillReturnRows(sqlmock.NewRows([]string{"address", "name"}).
					AddRow(testAddr1, testName1).AddRow(testAddr2, testName2),
				)
			e := newQueryExecutor(db, nil, `SELECT * FROM "items"`)
			qes.Equal(errUnsupportedScanStructsType, e.ScanStructsContext(context.Background(), test.items))
		})
	}
