我是否正确地从默认代码迁移到测试代码?

我想使用Lex的界面创建和开发一个聊天机器人,作为第一步,我找到了一个 ScheduleAppointment 默认bot,所以我决定对其进行调整。此bot中的默认提示为 date , time 和 appointmenttype . 作为第一步,我开始使用blueprint lex-make-appointment-python https://console.aws.amazon.com/lambda/home?region=us-east-1#/create/new?bp=lex-make-appointment-python 并且不得不更改那里的许多默认内容,例如,它有一个确切的约会时间和天数等,而在中进一步开发之前,我想使用的版本 lambda 是一个需要 ANY TIME 和 ANY DAY 例如,如果我要求安排约会,我不会出错 tomorrow 但是如果机器人问我日期,我会 hfujdhfu 或 banana 应该问我 what is the date? 再一次

所有这些都是我在调整代码后所说的和所做的:
