如何使用条带添加资金不足的支付源?

我正在尝试测试用户卡资金不足的情况。

在以下位置跟踪文档 https://stripe.com/docs/testing -卡号 4000 0000 0000 0002 会产生这样的错误。考虑来源 valid 在stripe sdk中,它生成一个源 token 但是当他们 create_source API,它返回时带有 Request req_nGnzPdJHjw4lrk: Your card was declined. -消息,即使我还没有创建任何收费。

文件位于 https://stripe.com/docs/saving-cards 状态:

Stripe validates card information when it is saved. This does not guarantee that any future charges succeed (e.g., the card no longer has sufficient funds, is reported lost or stolen, or if the account is closed). This process also includes the results of any checks, including traditional bank checks by Radar (e.g., CVC or postal code), that may have been performed.

所以我的问题是,当一张卡被Stripe接受,但在收取费用时资金不足时,如何测试一个场景?
